Ford 7.3L Power Stroke (1999-2003) :: A/C Blows Through Defrost Vent Only
My 99' started o blow air only through the defrost vent today, and won't go through any of the other vents. I think this happens when your vacuum pump goes bad or there is a leak, correct? If so, how can I test these to figure out the problem.
View 2 RepliesFord Ranger / B-Series :: 2003 - Heater Vent Selector Stuck On Defrost
There is always something.... I just drove my girlfriend's new 2003 ranger edge home from the seller. Real nice truck. I noticed the heater selector doesn't change the air flow. It is on full blast for the defrosters, and is also trickling out of the floor and dash vents. No matter where you put the selector, thats the only place the air comes out.
The temp control seem to work OK, when you turn it on cold, you get cold air and visa versa. Even on AC and MAx AC... air out the defrosters. It's cold when you turn the temp control to cold.
I did some searching here and gather some info on checking the vac lines etc. Everything looks in place but one detail. The vac ball under the hood under the air box has 2 ports on the front end, and only one grey line going into it. The other port has what looks like a rubber boot and part of a very short vac line broken off it.
I looked, I cant find any loose vac lines. I'd like to know if this second port is suppose to have a second line on it, and where does it go? What color is it? Is this the reason the vent selector isnt working?
Ford Wiring/Electrical :: 2000 - Clicking Coming From #2 Relay Switch Under The Dash
In an attempt to bleed my drivers side caliper today I noticed clicking coming from the #2 relay switch under the dash. The clicking stopped once I pulled out the relay. I continued to bleed my caliper which I've been having issues doing so. It was kinda odd how I was able to bleed the caliper after pulling the relay. Is it possible that the [email protected] system could be causing issues with the pcm? 2000 f 150 4.2 v6 232,000 miles .....
View 9 RepliesTouareg :: Clicking Noise Coming From Vent System - No Footwell Airflow
I've successfully managed to ignore the clicking noise coming from the vent system long enough that it eventually went away but I now have no air coming out from the footwell area on both the driver and passenger side. I am guessing that the diverter flap mechanism has either simply broken or is mechanically frozen in a certain position.
The air flow to the dash and defrost vents is fine. If I manually set the system to have all air come from the lower vents, there is a loud wind noise as the air is trying to force its way around a closed flap. Is this an easy fix or another expensive and problematic trip to the dealer?
Jeep - Grandcherokee :: 2003 - A/C And Heater Control Panel Switch Is Stuck In The Windshield Defrost Setting
I have a 2003 Jeep Grand Cherokee with about 240000 miles on the clock. Words cannot describe how impressed I am by this car. However, yesterday I noticed that the selector switch where one chooses to direct the air output has failed me. It seems to be stuck in the windshield defrost setting, unable to redirect the airflow to anywhere else. I am however still able to control the temperature as well as A/C settings. The switch felt strangely 'limp' almost as though it is no longer connected to whatever engineering or witchcraft it is attached to behind the control panel. What are your thoughts on this? Could it be as simple as some mechanical linkage that has snapped off? Just to recap: blower motor, heat and A/C are not affected by this.
View 2 RepliesFord A/C :: 2003 - Air Blows From Dash Vents Then From Defrost In Cycle?
My nav. when I put the air cond on auto and lower the temp so the air comes on, it blows out the vents on the front of the dash like it should and is cold. Then after about 30 seconds give or take, I hear a door deep inside the dash shut, or open, then the cold air only comes out the dash vents that are the defrosters for the windshield.
Then I can make it go back to the front vents again by pushing the button on the heater control to make the cold air come out the front vents again, but then it does the same thing again. Whats going to need to be replaced/repaired?
Cadillac - Deville :: 2003 - Humming Noise In The Front
I recently had a lot of repair done to my 2003 cadillac: new bearings in both front wheels, new power steering line, rotors turned, cv axel replaced.I also bought new Michelin "Symmetry" tires as I am taking a long trip.
I had Toyo tires with some wear and had them rotated at another place other than my mechanic's. After that I noticed the humming noise in the front; it sounds like it is coming fron the driver's side and is most noticeable when I drive 35 or 40 mph. My mechanic said he checked everything carefully and couldn't figure out the problem.

At times when going to start our 1998 Caddy you can turn the key and ..... nothing happens, no clicking ... nothing. Everything else works but it is like you are not even turning the key. Is there a weak spot on these cars?
I am familiar with solenoid/starter issues but this seems a bit different for some reason.
Montana :: 2001 - No Heat / Air Movement Via Defrost Vent

View 2 RepliesFord Excursion :: AC And Defrost / Vent Switching Back And Forth
I have to once and for all try to figure out what the heck is up with the AC and the defrost/vent switching back and forth. I have searched and searched and posted a few months back as well. But now that it's summer and 100 degrees out I've had a chance to test some more.
1 - I replaced both hoses going to the hubs up front.
2 - I am not sure how to test vacuum, but I did cap the hoses that lead to the hubs and still had the fluctuating back and forth
Looking for detail how to test for vacuum leak with a gauge directions ? What number is supposed to hold on the gauge and for how long etc...?
3 - It used to be that when I got to a high speed or RPM it would shift to defrost, but now I've noticed that once on the freeway going to work for instance and doing a constant 55-65 ( sub 2k rpm ) for about 20-25 minutes the vents hold fine. When I start to stop and go with higher RPM's it starts to 'break down' again. Could it be that there is a vacuum canister or pump ? I don't know ?? The diesels have a vac pump - do the V10's ? What can I check if there is no vacuum leak - what's next ?
Ford - Explorer :: 2004 - Air Only Blows Out Of The Defrost Vent
I've got a couple different problems. The first one is that no matter what setting I have it on, air only blows out of the defrost vent.. Why this is happening? or is there already a thread about this? i saw a thread for this same problem, but it was for 2nd gen explorers.
The second problem I have is that there always seems to be air blowing from some where on the passenger side, unless i am accelerating. I can't seem to find where it is coming from but it makes a really annoying noise.
It is the 4.6L, AWD. not sure if that matters or not though.
Ford F-150 (2004-2008) :: Remove The Defrost Vent Covers?
is there an way to remove the defrost vent covers? i think my license slid down the front of the defrost covers. its probably somewhere down under the dash. I would like to start removing the covers up top before I yank the dash. I am 1400 miles from home so I cant run and get a replacement.

The floor and defrost vents work. It just stays on defrost when you try to use the dash vents. The actuator seems to be working fine.

May be moving to alaska and kind of need my heater to work properly. . . .
