Ford F-150 (2004-2008) :: AC Blows Hot Air But Defrost Blowing Cold


Jul 16, 2014

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.

Ford F-150 (2004-2008) :: AC No Longer Blows Cold Air And Temp Gauge Dead

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.

Ford A/C :: 1997 F150 V6 - Cold Blowing Only Through Defrost Vents?

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.

1997 F-150 XLT, 4.2 Liter, V6, manual transmission.

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 - 1997-2003 :: 1998 - A/C Blowing Cold Via Floor Or Defrost Vents?

1998 F150 XLT 4.6l automatic,,,

Drove the truck on a trip the other day, about 650 miles with a loaded 5x8 trailer in tow. A/C started acting weird. When the truck was on level ground, or going down hill, the A/C was fine. Cold air coming out the correct dash vents. As soon as I started up hill, or put the truck under strain of acceleration, the A/C would stop blowing out the dash vents and would start coming out the floor or defrost vents, or just not come out anywhere.

When I turned the A/C off and just used the vent setting, it would do the same thing with the fresh air. I guessing this has something to do with my vacuum lines, somewhere. What I should be looking for and where?

Ford Excursion :: Rear A/C Blows Warm And Front Blowing Cold

The front a/c blows cold air but the 2nd row and back blows warm. Yes the temp dial is on cold on both dials. Is there a separate a/c clutch that I dont know about to ck the air gap? Is there a separate port to put freon in besides the front. I need to get this fixed because with my bulldogs in the back the heat will kill them.

Ford F-150 (2004-2008) :: Overheating / AC Quit Blowing Cold

Will the computer in a 2007 shut down the AC compressor in an overheating scenario because it would be considered non essential? Yesterday on my way home from work my AC quit blowing cold. I just had the compressor changed a couple of months ago so my first though was bad compressor. Then I noticed the temp gauge start to climb. The truck was over heating. There was a hole in the radiator. Now that the overheating problem is fixed the AC is again blowing cold. I just would like to know if I may be starting g to have issues with the compressor again or if it's natural for it to shut the compressor off because of overheating of the motor.

Ford F-150 (2004-2008) :: A/C Not Blowing Cold Air / Clutch Not Engaging

Here is my problem: A/C not blowing cold air, blower motor working fine, checked all relevant fuses for A/C and R202 relay under the hood. Everything is fine here. Next, low pressure switch, jumped, clutch does not engage. Next removed relay R202 (clutch relay) measured voltages (at female sockets) where pins 1 and 3 would go, voltage OK. Jumped where pins 3 and 5 would go (bypass to see if clutch engages) and it does. Appears that the pressure switches check out OK (low pressure and A/C cycling switch - although this one not sure). CarMD unit was used as well, and no codes generated so perhaps PCM is working OK? I'm stumped, as a loss of GND by PCM or perhaps a corroded or open wire issue??

Also, possible the A/C switch on the HVAC control could be bad, but the light comes on, (doesn't mean switch is good necessarily). The rest of that unit works fine, control ***** that is, fan speed adjusts properly, air flow looks good. It appears this is an electrical problem where the clutch is not getting juice but I don't know the source of the problem. However, I also noticed that when the clutch/compressor was running (temporarily as described above) cold air still didn't come out. This, I assume, would mean I would need to add refrigerant or re-charge the A/C AFTER I get the clutch to engage electrically. 2004 F-150 5.4L ....

Ford F-150 (2004-2008) :: AC Quits Blowing Cold And The Truck Shakes

I have A '06 f 150 4x4 with codes p303 and 307. I have changed plugs, coils, and injectors on all cylinders. Still nothing. It runs rough for a while and clears out for a mile or so and back to running bad. When it stumbles the a/c quits blowing cold and the truck shakes like crazy. The check engine light is on and blinks when it stumbles. Tired of just having parts changed. What else could it be?

Passat (B5) :: 2003 V6 AC Blows Hard But Quit Blowing Cold

Have 2003 V6 FWD Passat. A/C blows hard but quit blowing cold. Noticed last week, that sitting for a long light, A/C would quit blowing cold, then cycle on again every 20-30 sec. After worked fine. Yesterday no cold air.

Read on forums about the 384 relay. My electric fan is NOT coming on. Started car, turned A/C on high, and checked voltage on connecter to fan. was negligible. Car was fully warmed up, so i figure voltage should be 14.0 VDC

Making assumption that it is either the AC relay 384, or the fan relay but there are two, a 214 and a 213.

Ford Excursion :: A/C Blows From Defrost?

Every time I turn my Ex off and start is again I have to turn my A/C completely off then hit the A/C and Recycle button to get air to blow out of the panel vents or it will automatically blow out of defrost vents no matter what setting it was on when I turned ignition off. Is there a blend door actuator/some sort of air diverter on these like my old Yukon XL had? On the Yukon the driver and passenger vents would blow hot and cold.

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?

Ford Ranger / B-Series :: 2002 - A/C And Heat Blows Through Defrost Only?

I have a 2002 Ford Ranger 3.0L truck that, all of a sudden, has a problem with the HVAC system that blows air only thru the defrost vents even when selecting any other vent levels (defrost, face/middle or floor levels).

I did find a thread on another forum regarding this problem, only it was for the 95-01 Ranger model years, yet they say that the 2002 Ranger is not the same as those earlier models.

Ford F-150 (2009-2014) :: AC Blows Through Floor And Defrost Vents Only

I have a 2010 f-150. Started having issues with the blend door actuator located behind the radio so replaced that a couple months ago and fixed issue. Now the a/c will only blow through the defrost and floor vents. I replaced the lower blend door actuator thinking that might be the culprit, but did not fix the problem. What the solution might be.
