Ford A/C :: 2004 - Air Blows Behind Dash While Going Over 70 Mph?
Sep 21, 2011
When I took my 2004 Expedition to the Ford dealership they said everything looked fine and they couldn't recreate the problem because they are not allowed to go over the speed limit. Here is the issue:
If I drive on the highway over 70 mph for a good amount of time, eventually I can hear the air blow heavily behind the dash board (passenger side front corner) but barely any air blows out the vents. In order to correct the problem I have to stop or slow down below 60 mph. I've tried every combination possible of turning off the unit, turning on the heater, switching from auto to floor, back to auto without any success.
However, occasionally if I go over 70 for a long period of time and deal with the issue until I get to my destination, on a few occasions when I've stopped i can something drop like the a/c vent got stuck behind the dash. Very weird issue and a long trip over this past weekend was very unpleasant and I'm thinking about getting a new car because I can't take this issue any longer.

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?

2004 Ford Escape air conditioner works GREAT when sitting idle. Air conditioner blows HOT air while driving. Seems like the faster I go or the more load on the engine the hotter it blows. Weird?

Having difficulties with an air conditioner. 2006 KR F150. The air blows, but not cold. I just had everything checked in regards to pressures, freon, etc., but still only blows ambient temperatures.

My blower in my truck only blows at levels 3 and 4. Do the blower motor going out? Switch? Motor relay? I've read a bunch of things try?

I have a f150 2007 with a 4.2 in it. The CEL comes on and when this happens the air comes out the a/c vents and no where else. We have cleared the code out but it comes back on when we do clear it out the air blows out where the dial is set. I think there is a vac leak somewhere....

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.

I have an 06 F-150, there is lots of heat but it only blows on defrost. Is this the blend door motor or is it something else?

My AC blows hot air, like heater hot, but the defrost on cold blows cold air. At first the AC would cut out at low rpm's (stop sign or red light) and cut back on, now its nothing. But the defrost blowing cold, enough to fog up the windshield, tells me its not the compressor or freon.

Either running A/C or heat.. air only blows on the '2' and '4' setting.. so I have middle of the road or WOT when it comes to the amount of air. On the '1' setting nothing comes out and '3' setting is the exact same at the '2' setting. What is going on with this.

The AC in my F-150 Super crew Lariat 5.4 was just charged and works fine until the temp reaches ninety degrees, then it blows hot. What this could be?

I have a 2007 F150 Lariat with a 5.4 L engine. Bought it 6 weeks ago from the original owner. Has 50,000 miles on it. He had a Ford command start installed when it was new, and received a new key FOB at that time. When I drive the vehicle, sometimes the horn will start blowing and the lights start flashing which to me, indicates the trucks security alarm is activated. The only way to make it stop, is to hit the unlock button on the key FOB. It also does it sometimes when it's not running and I open a door. Previous owner had same problem so he disconnected the horn!!?!

2006 F150 King Ranch. My Air Conditioning no longer blows cold air. Additionally, the Temp Guage is pegged dead left. No movement at all even at normal operating temp. I've had the dealer replace 2 sensors and a wiring asy (XL3Z-14A411-AA). I still have the same problem. No cold air and the gauge is still pegged dead left.

My low-pressure hose got a hole in it and now my A/C only blows warm air due to the leaked refrigerant. How to remove the hose at the connections as it is not using standard steel hose clamps.

Like many Prius, mine has suffered from a persistent dash rattle. The dealer fixed it once while it was still under warranty, and it took an experienced technician several hours to disassemble the dash, fix the rattle, and put it all back together again. Eventually it started rattling again, and I have just lived with it rather than spend the time tearing apart the dash. I figured that any fix would be temporary, and I would likely cause another rattle trying to fix this one.
Well, a couple of days ago we were driving into the city. The rattle was particularly obnoxious, and seemed to be growing in intensity. I pressed on the dash in several places to see if made any difference. The rattle got louder and looser sounding, and then went "Tink!", like the sound of a falling screw, and then went silent. I can only assume that somewhere under my dash there is now a wayward screw. Hopefully it won't cause a short, but at least the rattle is gone for now.

My Prius air condition blows hot air sometimes, sometimes it works fine, warm weather seems to increase the problem. Took it to the dealer, they couldn't duplicate problem, said it was fine, but it is obviously not. Where should I start, don't like the replace parts till we figure it out thing. Don't think its the compressor b/c sometimes it works, sometimes it doesn't. Fan is working fine.

My 2006 Prius wouldn't start yesterday. The dash lights blinked on & off and the fob was locked in the dash. About 5 mins. later it came out. I was able to jump start the car with no prob. I drove to the dlr. & they checked the bat. & charging system. They found no problems, but said I might want to R & R the bat. as it's 5 yrs. I want to stick with the stock bat. Aalso stated that the bat. was fully charged & when I went home I plugged in my battery tender. The car was wired for the tender already although I haven't had the need to use it until now.

I have a Buick park avenue 1998, 3.8L V6 engine. the problem is: The ac vent on the driver's side blows cold air but on the passenger side blows EXTREMELY hot air. no matter how cold or hot you set the ac it blows at the same temperature on both sides. Florida heat is setting in and my passengers are melting. I am really hopping that is not something to bad and that I can fix it myself. Tip: this started happening after i had the alternator and the battery replaced.

My 2004 Liberty just started this a couple weeks ago. When sitting still, the AC blows hot air. It cools down nicely when you start moving. This makes traffic lights and people who don't go when the light turns green VERY annoying. While waiting, I can hear the compressor coming on and off. Thinking perhaps the radiator fan wasn't coming on, I looked at the radiator fan fuse, 40 amps, and it looks fine. I even checked it with an ohm meter. With the car sitting still, engine running and AC on, I don't think the radiator fan is going. Maybe one of these two relays?

Over the winter, the A/C in my '04 Mitsubishi Galant quit working. It wouldn't blow any cold air at all, but I didn't mind too much since it wasn't hot out. In preparation for a hot NC summer, I took my car to a dealership about a month and a half ago to have the A/C fixed. They replaced the condenser, and the car started blowing cold air, but it would only do so intermittently. Two weeks later, took the car back into the dealership for them to have a look, but it blew cold air during the entire time that the mechanic was looking at it. I specifically asked about the compressor, but he said that it seemed to be fine. Since then, I've been trying to figure out what causes the A/C to stop working.
I haven't been able to find an exact cause, but the A/C will typically blow cold air when the car is not moving or when I am braking. It is also more likely to work if it isn't hot outside (which isn't exactly useful). If I am on the highway, applying the gas, or if it is hot outside, it is much less likely to work. As I am driving, I can hear the A/C click on and off; for example, if I apply the brake, I will hear the A/C click on, and it will blow cold air briefly (around 30sec - 1min or so). To complicate things, recently the A/C has blown fog in addition to cold air. This has happened three times. I'm at a loss for what the issue is...

I have a 2004 Gen II that blows the A/C(Htr) 10 amp fuse. The dealer changed the inverter and replaced the fuse with a 15 amps which masked the problem. I have looked at the items that this feeds and have eliminated the: inverter (Dealer knows very little, Scary), A/C Control assembly, heater water pump assembly. I thought that since the Heater water pump assembly runs intermittently it might be that. Or could it be the diode in the relay that controls it? I cannot seem to find where it is located..
