Here's the situation....It blows cold for about 5 mins, then the air starts to warm and stays warm. I just bought the truck 06 350 crew cab and they supposedly charged the system. I'm wondering if it has a leak but it should start out blowing warm air? I just wanted some thoughts before I start throwing money at it.
View 1 RepliesI am the proud owner of a 2002 F250 Super Duty 4x4, which has 158K miles on it. I live in South Florida and use the truck as my daily driver and also from trips up into the Blue Ridge Mountains.
Recently, I noticed that when I have the A/C on it blows nice and cold for about 15 minutes, but then the air gets really warm. I had the system checked and the Freon levels are right where they should be. A bit of experimenting reveals that if I turn off the A/C for about 10 or 15 minutes after it starts to blow warm air, the systems blows cool air as it is supposed to.
Therefore, I suspect that something is freezing under the hood and preventing the system from operating properly. Since A/C is pretty well essential for us in south Florida, this is a problem, when I have the family or customers in the truck.
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.

AC will blow cold, then shift to blowing warm, muggy air, then back to cold. Seems to be some relationship with throttle movement. Cruising steady ac seems normal. Multiple throttle shifts in changing traffic seems to trigger the warm air. Once accelerate back to normal cruise, can feel clutch/compressor shift and blows cold again.
Any ideas? I have read a possible cause can be the ac clutch can wear and need to remove spacers? Is this a DIY job? What about the ac clutch relay switch? On reading an online repair manual, seems that the clutch is magnetic, and if no battery power to clutch, it removes itself from compressor?
Just had an EGR delete kit installed. Any relationship to this and ac problem?
So the other morning I drive the 140 miles out of town to work for the week. when I pull up to the job site the cooling fans were revving really really high! never heard this before. then it went back to normal after I opened the gate and parked my truck and shut it off. I'm driving maybe 5 miles tops to the job and back to the motel every day. however that is far enough that my heater should be warming up and it's not even coming close to warm. it blows cold air. and to compound that I'm not sure the cooling fans are even working. they don't appear to be. Is there a connection here?

Heat blows warm at best and A/C isn't all that cold. I want to believe its a blend door issue and dive into it this weekend and fix it but there isn't a single piece of foam coming out of any of the vents. Of all the systems on the car, HVAC isn't my cup of tea I don't know anything about it. What else could be the problem? I can live without A/C but the heat things must be fixed.
View 4 RepliesSo i just had my R32 at the stealership to get my AC recharged. Ever since ive noticed that my AC doesn't always blow cold. It will vary from cold to warm and back to cold then warm. Im not even sure what to start looking for as the issue
View 2 RepliesMy AC blows cold for a little while, then it blows warm. If I wait and turn it back on the cycle repeats it self. I had the freon filled. Not sure what to do? 1997 nissan pickup....

View 8 RepliesThe air coming out the right front vents is cold; but, the air coming out the left front vents (driver's side) is warm. Sliding left ac slider switch up and down did no good. Considered fuse, but both left and right AC controls run through same fuse. Suspect bad motor for left side plenum duct, or bad connection, or faulty vacuum at motor (if motor is vacuum actuated). Considering removing dash cover to see if I can find the motor, but not sure how to remove dash cover, or even if that's the way to find the motor.
View 7 RepliesI have a 2009 Camry LE (4 cylinder) that has an intermittent operating A/C unit. The blower will always work, however the cold A/C only operates intermittently, but the unit will continue to blow warm air half the time and cold air the other half of the time while in the cold mode.
I read that there is a relay fuse in the 5th Generation Camry, which sounds like my problem, however, I am not able to locate such a fuse in the 6th Gen Camry.
Could it be a relay fuse? Any other culprits? I would like to see if this is a problem that I can fix.
I have a '12 Focus and for no apparent reason the A/C will turn off and warm air enters the car for 1-3 minutes and then returns to normal cold A/C air. It doesn't matter if it's on "max A/C" which will circulate the air inside the car or just the coldest setting on the A/C, high fan, low fan, it just happens. What usually happens is that I'm driving 40 or 45, then have to slow down (stoplight, etc.) and speed up again, during the slow down is when the A/C turns off and warm air enters the car. As soon as I'm driving 45 again for a minute it usually kicks back to cold air. OR, while driving on the freeway at 60 - 70mph after about 15-20 minutes it all of a sudden stops cooling and I get warm air in the car. It's been checked by 2 different dealers already 4 times and they never found anything wrong with the A/C System. It did have an actual leak a few weeks ago and that got repaired but it still has this mysterious behavior.
View 5 RepliesMy 2009 silverado ltz is haveing heating issues. when you first start truck all work fine. After a couple min the drivers side vents loose heat and blows cold air. the heat on the pass side works fine. then the vent will change to defrost even though the display still shows its on vent. the only way to get it back is to mess with the vent control. then it will last about a min then back to defrost. at this point i just turn it off. I have already replaced the control panel to no avail ...
View 1 RepliesMy Prius has 198K, runs great and has been trouble free. This week it started acting up. The AC will run for a few minutes, blowing very cold, then will blow warm air for a period of time, perhaps 10 minutes, then will blow cold again for a few minutes. It will repeat this several times, then will blow cold until the end of the trip, about another 30 minutes.

View 3 RepliesWhen first starting a 2012 Sante Fe GLS with standard AC each morning, the vents blow warm for up to 3-5 minutes and therafter are fine. Additional starts for the remainder of the day seem fine. We live in a hot climate, but our 2011 Sonata, which is parked in the same garage, does not have this problem. No unusual soundsor lack of air circulation, and after 5 minutes it spontaneously starts to blow cool air. Problem began 2 months after purchase.
View 4 RepliesI have a problem here which isn't funny around 30F. The engine temperature act quite normal after a cold start, but the heating inside is disabled somehow. So I can select any temperature in the front and back, but it stays cold.
View 14 RepliesIt seems the local dealership has finally figured out why the rear ac blows warm while the front blows cold. It only took 5 trips.
The part # comes out to F75Z19A522AA or F75Z-19A522-AA. Its listed on Tousley and other online parts outlet but so far all that I have called said it is no obsolete and they are no longer available from Ford.
Rear inlet door actuator - obsolete part? Where I can find this part (I'll even consider used)?
Tested/checked the blend door, actuator, Low pressure cycling switch, compressor clutch and they all work. The accumulator does not condense, or at least that I've noticed. The gauge on a can of R134a reads 55 at 85 degrees outside. Anything else I can check to diagnose a problem?
