Ford 7.3L Power Stroke (1999-2003) :: A/C At High Speed Makes Sound Like Blower Hitting?
When I turn on my fan for the AC or vent or heat, it works just fine on the first and second settings. When I move the fan speed to the third and last speed, I hear this sound that sounds like the blower fan is hitting something. I turn the speed back to the lower two settings and noise goes away. Sometimes I turn it back to the higher settings and the noise actually will go away but most of the time the noise is there.
I pulled the blower motor out yesterday and set it to where I can turn it on while out of the compartment and I didn't really notice a noise. I wonder if the noise is there but I am just not hearing it since it is not enclosed in the compartment? I also noticed there is a crack in the fan where it mounts to the shaft starting at the shaft and extending out one direction and also 180 degrees the other direction. Thoughts on if the motor is bad or just the fan? Or even something else that I may not be seeing?

My mom has a 1988 350 Econoline van chasis that is a motorhome class C.
The front heater/AC blower motor only works when it wants to. It starts very intermittently and then shuts off then you go down the road a little more and it comes back on, it will do the same thing sitting in the driveway just idling. There is no timing it, it just turns on when it wants to and then back off again.
I checked the fuses and the fuses are fine. The blower motor when hooked up directly to the battery blows fine. When it isnt working of course there is no juice going to the blower motor through the hotwire of the blower motor, I have checked this with my volt meter.
I did replace the switch that turns the blower on in the dahs, and it didnt do the trick.
Passat (B6) :: Blower Motor Malfunction - A/C Only Works On 4
So my AC only works on 4 (no 1, 2, 3). I replaced the resistor as is often the culprit. NOTHING. Still only works on 4. So I unplugged the resistor all together, still only works on 4. So, either my new replacement resistor is also bad (unlikely), or it's the blower motor.

Thought for sure that would fix my fan speed, but nope. Replaced blower control module, Still only blows on the highest setting. Didn't try running it on auto, but that's what it did on manually turning the speed up. What else could it be?
View 9 RepliesCamry :: Subtle Clicking Noise - Blower Motor Works Intermittently
So for a few months now, my car has been making a subtle clicking noise whenever I have the ac or heat on, kind of similar to the noise spokes on a bike would make when children put a card in them. The noise increases/decreases in speed as I adjust the ac/heater speed.
Recently though, it's gotten to a point where sometimes, the blower motor would completely stop working. I can still feel heat and cold coming through the vents when I turn the AC on, but the it doesn't always blow air. I've noticed that sometimes when I hit a bump in the road, it starts working again. It works at all settings and all temperatures perfectly (when it's working that is).
How should I proceed? I don't know much about cars, but from what I've seen on the internet, it doesn't seem too difficult to replace the blower motor. I just want to be sure that the blower motor is indeed the cause, because I don't want to install a new one to be disappointed when I turn it on and still have the same issue. And winter is just around the corner so I would love to get this taken care of.
Sonata NF (2006-10) :: Manual AC Controls - Blower Motor Works Intermittently
My wife has a 06 Sonata with the Manual AC controls. The blower motor works intermittently. Sometimes it works, other times it does not. It does not matter which setting the HVAC is in. Yesterday while driving it, we went over a bump in the road and the motor started running again. Since the motor runs, I want to discount the fuse and relay.

View 1 RepliesFord 7.3L Power Stroke (1999-2003) :: Intermittent Rough Motor / Black Smoke And Low Power
I have an Excursion with 220k miles. I've owned the truck for 6+ years and had very few problems. I change my own oil and fuel filters, but beyond that I know next to nothing about the diesel motor. I do run a DP Tuner with the standard 80 hp program. And a 4" exhaust. Everything else is stock. I do keep it plugged it for the oil heater and the battery tender just about all the time now.
This latest issue started yesterday morning when my wife jumped in a cool truck to take the kids to the dentist (not warmed up but still 55 degrees ambient). A few miles down the road (35 mph max) the motor began stumbling and rocking and black smoke coming from the exhaust with reduced power. She pulled off and kept it running (very rough and rocking) and put it in park for a minute. When she put back in drive, it shifted heavily but the power was normal so she went on her way without any problems. The only report I got sounded like the motor was just cold and rough, so I thought nothing more of it.
Yesterday evening we drove it about 70 miles on the highway (72 mph max) with no issue at all, but when we continued on surface streets toward our destination (50 mph max) it did the same thing, but would not settle back down. I kid you not that it went through gallons of fuel the last 12 miles or so, just dumping black smoke out the exhaust. It felt to me like we were running 1/2 the motor, like the plugs weren't lit. Very rough and rocking and very little power (comparatively, at least). I had to switch to manually shifting the trans to get going and the shifts were much rougher than usual. Idle was low and rough but it never stalled. Behind me there was a huge smoke screen this entire time.
We made it to our destination and parked it. Did our thing and after 5 hours went out with finger crossed. Started right up and ran perfectly the entire 91 miles home. No motor or trans issues at all. Currently running 10/40 synthetic oil that I just changed about 2000 miles ago. Oil level is perfect. 3/4 tank of fuel with standard level of Diesel Kleen added. Fuel filter is less than 10k miles old. Temps yesterday were 65-70 on the drive down and 50-55 on the way back.
I jiggled all sorts of connectors this morning and didn't find anything loose.
Ford 7.3L Power Stroke (1999-2003) :: 2000 - Oil Leaking From Motor?
I have a 2000 f250 super duty extended cab with the 7.3 diesel and auto tranny which the tranny was rebuilt by Samco about 7 years ago and I have 337,000 miles on engine I had a oil leak from I believe my oil cooler which I fixed, but I am still losing oil, about a gallon or more every other day and in that time frame I am only driving maybe 30 miles. I have no drips, and I seriously don't believe it's burning because the truck is not smoking even when you rev the motor up. the bottom of the rear of motor is coated with oil plus as is part of tranny and some front of motor bottom. What to look for?

So I was in the process of doing a turbo swap to the borg warner sxe366 and the freeze plug that plugs the old mechanical fuel pump in the valley had to be removed well needless to say, it as well as the safety bolt I had attached to it fell into the motor, seperatly. I'm already getting the motor ready to be pulled but what are the odds that they made it to the oil pan or if they didn't any way to make them fall out?
View 10 RepliesFord 7.3L Power Stroke (1999-2003) :: Blower Fan Intermittent / Resistor Pack Plug Partially Melted
Coming home from the shore and turned of the air but not blower. No speeds at all. Fiddled with it until I got to a rest stop. KOEO, tapping the blower did nothing and swapping relays did nothing. 40 amp fuse and inside #22 ok. Had some time last week and discovered that power to blower was intermittent. Pulled the resistor pack plug and it was partially melted and upon removal of resistor pack I could see it was toast. Replaced that and pigtail and still got intermittent blower and intermittent voltage at blower connector.
Days go by with only a chance of it working but noticed it turned on more when I started the truck with the blower motor switch turned on. Maybe bad contacts somewhere or maybe loose connector in harness I thought. I had been meaning to replace some burned out cluster bulbs with new LED's, so I bought a motor switch and did both items. Left the front dash part off because nothing changed as far as the blower was concerned.
I downloaded the schematic to end the frustration and see the power going into Mode Selector switch, black/yellow. My test probe gets nothing through insulation with KOEO. Pulling the connector and probing the contact of the blk wire and I get blower all speeds but no light glowing from test probe as if I just grounding it. I have to add that 1/2 the time I got not blower and 1/2 the time I did, so It was intermittent there as well. Doing this again several times while restarting the key to run and still the same until after about 8 times, I finally get a light on the probe, probing the wire while its connected and I get it now with it disconnected and all seems ok. I have blower each time for the last dozen restarts and I cant make any sense of it.
I just have a feeling this good heat isn't going to last. Should I replace the Mode Selector Switch? It seems the relay coil wasn't energizing but now it is. Last week I shot the relay seat with contact cleaner and replaced it with new napa one out of frustration.
Ford 7.3L Power Stroke (1999-2003) :: Motor Turned Over / Loading Up And Won't Start
I have a 2000 F350 with a 7.3 I have just set a brand new motor in this truck with everything in it new including the transmission injectors are 175/146 from Thoroughbred Diesel. The engine is Bored 40 over studded heads return regulator system as well as a pre pump filter and a javelin and Hutch mod on the tank. When we went to start this new motor the motor turned over and sounded like it was going to fire off pretty quick but instead I'm just getting white smoke and lots of it.
I failed to mention that the injectors are single shot vs. Split shot and then I did have the programmer Tuned to these injectors through thoroughbred there is no fuel in the oil no water in the oil no oil in the water everything seems to be good all the pressures seem to be good and at this point I am lost no one that I have found in the area, where to begin. Seems to me that this is a loading up issue and it seems to me that the only thing that could be causing this would be programming but I don't know.
Ford 7.3L Power Stroke (1999-2003) :: 2001 - Won't Start When Motor Cold?
I have. 2001 excursion with a 7.3l deisel. 167100 miles
It runs great but if it sets over night when the motor is cold it will not start.
You have to plug the block heater in for about an hour or more for it to start.
To me it seems like glow plugs are not working? It had new glow plugs out in from the po.
Ford 7.3L Power Stroke (1999-2003) :: Bower Motor Stop Working
For the past few months my bower motor will stop working. It could stop while I'm driving. Or not work when i start the truck, then start working while I'm driving down the road. When it was working it worked fine. It had the different fan speeds like it was supposed to. It would just not work at all, or work fine. Now it doesn't work at all. I checked all fuses, and swapped the relay for the windshield wiper relay that i know works and still nothing.
I unplugged the blower motor and put 12v to it and it didn't work so i thought i found the problem. Took out the blower motor put power to it again and it spun just fine. Plugged it back into the harness and it worked other than no low speed. Flipped the switch back and forth, then low speed worked, up to high, but no difference between speed 2-3. Put it all back together and it seemed like all the speeds were working fine. Day later, won't work at all again.

View 3 RepliesFord Excursion :: Blower Motor Only Blows On High?
Well my blower motor only blows on high which IMO points to the resistor, went and bought one and still only blows on high. Tried to test the plug that goes to the resistor but couldn't get anything, shouldn't there be 12v going to the plug and then step down to the resistor until high is selected then 12v bypasses the resistor all together? Blows strong and cold, too cold actually since we cant turn the blower down so we have to turn it off for a few minutes.

Ford 7.3L Power Stroke (1999-2003) :: 2001 - Cylinder Missing Until Motor Warms Up
My feed truck (2001 ext cab 4x4 7.3 198k) had a cold starting issue I fixed with new gp relay. Now I noticed when it gets down below 30 degrees it has a cylinder miss until motor warms up. I don't doubt injectors are in my future. I was wondering though if that is common for worn injectors or if maybe something else has gone haywire and how long can I run it like that before something else tears up? after about 7-10 min the miss goes away and I don't notice it. I would like to get through the winter before messing with it or having injectors put in it...
