Ford A/C :: 2003 F150 FX4 - Air Conditioning Will Only Blow Through The Defrost
May 31, 2012
I have a 2003 Model F150 4x4 that has always ran good for me, and has only had minor issues ever since I've had it. Not too bad considering it has 266,xxx miles on it and running 100 miles a day on the original motor & transmission.
Here's my problem - my air conditioning will only blow thru the defrost. I can hit vent on the control panel and it will blow thru the vents, but if i hit max ac it switches to defrost. I live close to Memphis, and it has gotten super hot around here and i really need this to work correctly. I have looked under the hood looking for messed up vacuum lines but haven't seen any that looked bad.

I'm not very knowledgeable about this stuff (have worked more on older vehicles) so i guess I'll need a fairly detailed reply if possible.

I have a 2003 Santa fe 2.0 diesel which I got 2 weeks ago, but the air con does not blow cold, I suspect that the air conditioning needs re-gassing, my question is how often does the air con need re-gassing on the santa fe, I've had cars before and for a number of years and the sir con always have been fine, I just hope it needs a re-service , are there any common faults with the air cons on a santa fe?

2007 Ford F150 half-ton. No cooling of air at the outlet of the ductwork. Freon charge is good, I watched the tech pull the system down and hold it for the prescribed time period. Compressor will not start. I am being told that this means a failed compressor, but I am of the idea that the pressure switch for low pressure must have failed, or the orifice is stopped up. I am also being told that the compressor, evaporator, and orifice tube needs replaced in order to remedy this issue. The counter man at my local parts house cannot find in his computer any pressure switches, kinda making me think that everything is in the unit. In short, if I can avoid buying the compressor, I would like to.

I have an 01 Jetta 1.8t wolfsburg eddition and the AC won't blow cold air. The AC Clutch does engage when I press the AC button on the control unit The refrigerant pressure is good The fan blows, but its hot air. the condenser is working because the pipe is cold when the ac is running I am curious if any of you know what other possible problems could be causing this. It is currently 100 degrees with 100% humidity

Ok here is the issue, my girlfriend owns a MK4 '99 Jetta. Through the search I was able to figure out why she is having so many issues with her door locks and how they can be fixed on the cheap..thats awesome. But here is the problem. She was driving down the road the other day, A/C working...then suddenly it stopped blowing cold. Fan is still working, just blows hot air. She said it started blowing warm suddenly and hasnt been getting warmer through out the past days or anything.
With the hood popped and the a/c on, you can see that the compressor isnt engaging. The car makes a noise like its engaging the compressor, but nothing is happening that I can see visually. Seems as if the compressor is not getting the signal to engage. It sounds like its trying to make the compressor kick on about every 5 seconds or so. Basically that initial clicking sound that your hear RIGHT before the compressor comes on when its working normally.
We have checked the fuses and no luck with those, all look good. Seems like its an electrical issue to me. What this may be? Bad pressure switch? Low pressure in the system? I know the car has had the compressor replaced before...and the clutch seems to spin freely when the car is off.

My windows do not defrost. Blows hot air and seems to blow out defrost vents ok. When I bought the truck last winter no problem untiL A /C would not cool cab in summer. Now it's winter and no defrost.. I have takin into dealer and they said compressor is kicking on ok but still no moisture leaves the cab. It is dry here in Kansas so when we get rain I will have to sponge the windows.

I have a '90 F150 without A/C. For some reason the healing system is stuck on defrost. No matter where I turn the selector switch ( floor, vent, etc) air only comes out the defrost. If I turn it to "off" it will turn off. What is wrong?

My A/C is blowing cold but only thru the defrost vents. First it was blowing normally from the dash but during acceleration or under load, the a/c would randomly blow from any vent, from the floor, dash, defrost. Now that stopped and it only blows from the defrost vents above the dash-board.

I just picked up a 78 F150 Ranger XLT with a 351M in it this past friday. I am absolutely in LOVE with her. She is a great solid truck. One issue I am having though is that she blows hot air out the vents over the hump but nothing is coming out the top of the dash. I am guessing that i will have to take the dash off and clean out the box check the door etc. What did you do to rectify?

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.

I seem to be having an issue with my air conditioning. I don't think it's an ID-10T error, but it is very peculiar.
My driver side vents blow hot or lukewarm air, however my passenger vents are ice cold. I have the 15 limited, so it does have the "dual" control, and as such I think the issue may be related to that.
Both controls are set to low, max fan, head only, and AC. The "Sync" and "Auto" buttons have no effect.
Any things I can check? I really do not want to bring it into the dealer as they treated me very poorly the last time I came in and my car was out for a month.

My uncles 99 f150 is acting a little strange. When he steps on the gas, the air conditioning comes out of the defroster vents. What's going on?

I'm at the end of my rope! My 2005 Ford Five Hundred Limited has a constant problem with the A/C system and overheating. In the last year I've replaced the compress, expansion valve, dryer FOUR times. They have replaced the condenser, blower motor, and added Freon, and checked for leaks. It will blow cold when running fast and then blow hot. They have replaced belts pulleys, They have replaced the thermostat, fans, coolant reservoir, hoses. and it still overheats. I've taken it to 4 difference mechanics including two dealerships. No one can seem to fix this problem.

Mile marker hubs on my rig. V10. Plugged 2 ports on what I thought was the vacuum pump pass side middle of the fender. The lines coming out of what I thought was the vacuum pump were molded together going into two separate ports. I plugged both ports. What did I do wrong and what should I plug?

I have a 2003 Saturn Ion, 5-speed, manual transmission, with about 95,000 miles. This week, whenever I turn on the air conditioning (high, low, or in-between) a whirring or revving or rumbling sound comes from under the hood, close to the car, center or passenger side. It sounds I'm driving a huge truck. The sound doesn't change with RPMs or MPHs, idling/neutral or in any gear.
The sound will begin shortly after I turn on the a/c and sometimes stop by itself. When it stops, especially if I'm not moving, the car gets so quiet (and there's just maybe a hint of hesitation) that it almost seems like the car has stalled. When I turn off the the air conditioning, the noise stops just after. But the whole time the a/c is on, it's working just fine, nice and cool.
