Ford Super Duty (1999-2016) :: 2005 F350 - AC Will Not Cycle / Blower Only Blow On High
2005 F350 Lariat ..... I cant get my AC to work in my truck.
AC will not cycle on, Originally thought the system was low because I jumped the pressure switch and it cycled fine (But did not cool inside the vehicle). Checked the pressure and it was in the 40lb range on the low side. My blower will only blow on high but I assumed it was a defective fan speed control.. Possibly an issue with the climate control?
Ford Super Duty (1999-2016) :: 2000 F250 - A/C Wouldn't Blow Cold Suddenly
My 2000 F250 SD 5.4 AWD's A/C wouldn't blow cold suddenly the other day. I confirmed the A/C relay (engine compartment, 3rd down from firewall)was "clicking" but compressor clutch was obviously not engaging with dash switch on Max A/C and engine running. When I take of the 2 wire connector to compressor to see if it is getting power, the truck won't start..if I disconnect the A/C compressor plug while running, the engine similarly quits. I have never had another vehicle do this on me before..I could unplug the compressor on my Jeep GC, for instance, measure 12+ volts with A/C ON w/car running and no problem with Jeep engine turning off.
I have searched for A/C wiring schematic w/o success. I checked every fuse in cab/engine for continuity since I don't know which ones might deal with A/C..jumped hi/lo pressure switch connectors with engine running/A/C ON w/o compressor clutch engaging. Clutch turns easily, have banged it a few times, and air gap looks good. More bizarrerly, I hooked the compressor to a 12V/ground via its 2 male prongs and didn't get the clutch to engage.
Ford Super Duty (1999-2016) :: Heater And AC / Blower Doesn't Seem To Blow Very Hard
My blower doesn't seem to blow very hard. I've been in other fords and the ac and heat blows great. Someone suggested that that I pull the fan motor and clean the blades.

So two weeks ago I had a battery melt on me and I replaced it. Then last week I had the other battery almost blow up on me (it was a mess and smoking). I didnt use it all weekend. Today it started right up. I drove it like 500 feet and it just died. It is very weird. Both batteries are fully charged. Relay is good. When I put in the key it does nothing. No sound no radio no clicking. However, the gps still works (the online monitoring kind). I can fold in my out revie mirrors. And I can lock and unlock the doors. and the interior overhead lights come on. Nothing else has power at all. And I can't put it in neutral. Right now the truck is blocking my driveway so nothing can get in or our of here. I am wondering if it is some type of antitheft issue...

I have an 01 F250 with a v10. Driving through heavy snow in 2013 a plug blew out. Should I expect this to happen again if I do some heavy hauling and should I do something preemptive?

Only 2 speeds of the 4 speeds are working on my blower. I was thinking it may be the switch, but someone at the shop told me to replace the blower resistor first. I did that and still only have 2 speeds. Im guessing I need to replace the switch now?
Also, I am having problems with my heat adjustment. I have it set to warm (half way between cold and hot) and out of the blue it will start blowing hot. I turn it down all the way to cold until it blows cold air and turn it back to warm, and it will be fine for a few minutes and start blowing hot again. Vacuum problem? blend door problem? How would I go about trouble shooting this problem?
Ford Super Duty (1999-2016) :: 2008 F250 - Telescoping Mirrors Blow Fuse Right Away
I'm having an issue on my 2008 f250 power stroke. My telescoping mirrors are causing the fuse to blow instantly when I hit the button. Where to start looking for a short?

Sunday I bought a 2001 f250/5.4 to replace my 91 f250. I didnt drive it yesterday, but this morning on my drive to work the heater was very weak, it seemed to blow warm for the most part, but was barely pushing air even on high. I flipped it over to A/C to see if it blew any harder and it did. Does the blower motor need replace? if so why does the AC blow harder than the heater?

I had a 2014 F-250 I bought new. Absolutely loved the truck. Things got tight so I decided to sell it yesterday. I'm now looking at a 2005 F-250 with 113k miles. It's got a lift, 37" tires, DPF delete, pretty sure the EGR delete but not sure exactly what to look for under the hood. A ton of LED light bars, SCT tuner, I was told its bulletproofed by a dealer, and it's a king ranch. It runs great. I plan on having a diesel mechanic look it over but here are my concerns. It does have a slight bit of blow by coming from dipstick. Very little. Also a slight oil leak that looks like it's coming from the bell housing so maybe rear seal?

Very strange things happening with 2009 F350 Gas, first the heater blower only is now working on high, progressively has gotten worse, low settings started not working a while ago, now only high works. Just recently the strangest thing, start the truck OK, turn on radio OK, turn lights on then the radio goes off. Will bring it to dealer in a day or two if I can't figure this one out.

My Blower motor is intermittently going on and off. After messing with it for a while it seems to stay on. Motor may be going out. Not real easy to change the blower motor on this 2008. Haynes manual says to take the 2008 and up trucks to the dealer.

Ford Super Duty (1999-2016) :: F250 - Blower Works Sometimes Then For No Reason Stops
1999 F250 .. Blower works some times then for no reason stops. When it works, I have all speeds, it makes no odd noises. I shut the engine off and then it does not work. I have power to the blower motor even when it is not working. I doubt it is the speed resistor module because that is not used in high speed. I've taken the blower motor out of its housing and pulled the resistor module as well. I find nothing wrong, power it up and the blower works. I put it all back together and it does not work.
View 4 RepliesFord Super Duty (1999-2016) :: 2001 - Suddenly High Idle / No Blower And Hard Shift
My '01 recently seized up and a buddy determined it was the AC pump. Replaced the belt with the bypass version. A month later, I moved across the state to Iowa. A couple weeks into living here I turned the truck on and it was idling really high (about 2500-3000) but would settle down to around 1100 when put in gear. However, shifting into gear is causing a progressively worse "jump" into gear. Hadn't really had the money or the time to take it in so I let it mostly sit unless I absolutely needed the truck.
Today, the idle is still high and does seem to cycle a bit in that it will rev up close to 3000 then settle back down around 2200 or so and then rev back up again and so on. I backed it down the drive into the sun for a little warmth and it darn near jumped a foot when I shifted. I turned the heater on defrost so I could clear the windshield and absolutely nothing came out.
I can't get into a garage for a few days to get it hooked up for diagnostics. So I thought I'd try here. My research leads me to think part of my problem may be a vacuum leak and/or maybe a sensor somewhere.
Ford Super Duty (1999-2016) :: 2000 - AC Clutch Locks In But Blower Will Not Run
I have a 2000 F250 and the blower motor stopped working, the a/c clutch locks in but the blower will not run. I back tracked and I have no power at the motor or the resistors, or the speed switch. There has to be a relay that is turned on by the a/c selector to power the blower circuit. I guess my question is need a schematic of the a/c circuits? Or the location of the relay?

I have and 07 F250 and the #2 speed for the blower motor don't work (hasn't since I bought it) I read that the most common cause of this is the resistor under the hood on the firewall so I replaced that and still no 2nd speed??? Where I look next? Motor itself maybe?

My HVAC blower motor stopped today while the wife was driving the F250. I thought I should swap relays (with the heated mirror relay - same Ford Part Number) to rule it out or identify it as the culprit. However, since these are close to the firewall, I have a hard time getting the grip and leverage to pull the relay out of the Battery Junction Box (BJB). How to make this a bit easier?
View 5 RepliesFord Super Duty (1999-2016) :: 2006 F250 - Climate Control / AC Vents To Defrost And Blow Normal Air Through
I have a 2006 F-250 Super Cab with climate control. The last three years when the temp exceeds about 85 degrees outside it acts up. It will switch from the AC vents to defrost and blow normal air through, not ac cold. Then it will switch back, when doing so I can hear the internal deflector shudder. It will do this every few minutes. It is extremely annoying. All other times of the year it works fine. My local dealer had the truck last year, but could not find anything wrong. I have used the search and also Googled and while I find similar problems nothing exactly the same.

Another question on this, my 2008 F250 with auto climate has decided to only blow heat on the passenger side...do you agree that it is an actuator? If so how hard or easy is this to fix and what is the best fix.
While here, on another note, I noticed a rubber line hanging right over my front diff it looks like it could go onto a nipple coming off the diff? Is this a vacuum line for the diff that I need to put back?
