Pontiac - G5 :: 2008 - AC Will Only Blow Out Heat
Mar 17, 2014
I have had my 2008 Pontiac G5 since 2009. I got it used with about 32000 miles and it currently has 110,000 miles. It is the basic model G5. I love my car and want to keep it for a long time. It is in great condition except for one problem: the A/C. So it basically only will blow out heat, even if I have everything off. Sometime if I turn the knob quickly from Cold to hot to cold I will get some cold air but only for a few minutes. The thing is I just can't turn it off as it is always blowing out some hot air which makes my car miserably hot in the summer.
Also when it does blow out cold air, the fan is weaker then with hot air. All these issues have gotten progressively worse over the last few years. It used to be that at times I would have A/C for long periods of time when I did the rapid spin of the knob but now the spinning of the knob does not even work. I have had many repair shops to get it fixed but nothing has worked (people have tried new Freon, fixing the door part that flips from hot to cold,etc.) What could be my issue? I want to keep my car but making any long trips is very difficult in any weather above 75 degrees as the car becomes a sauna. I have had this problem for the last 4 summers and just want it fixed already! I want a car with A/C.

Another question on this, my 2008 F250 with auto climate has decided to only blow heat on the passenger side...do you agree that it is an actuator? If so how hard or easy is this to fix and what is the best fix.
While here, on another note, I noticed a rubber line hanging right over my front diff it looks like it could go onto a nipple coming off the diff? Is this a vacuum line for the diff that I need to put back?

I just got a 96 Grand Am for second vehicle, but it won't blow any air (hot or cold), I checked fuses they all look good. I'm thinking possibly blower motor, but wanted to get some feedback before I start plugging away.

2001 Ford Escape.
Blend door seems to be moving properly...(or at least the control arm is...) Truck gets up to operating temperature quickly enough.
It does blow warm air, but never gets hot...can't keep up with single digit temps. Every thing looks to be operating properly...

Problem: Not heat will come out unless
1) I don't turn on the Fan Motor at all. Very Nice heat will "bleed" out of the vents as long as there is no Fan on - on any setting.
2) Lukewarm heat will come out if I am giving the car gas or revving it. As soon as it goes back to idle or I am no longer giving gas it goes back to no heat at all.
Things I have tried:
Topped up the radiator and tank (radiator has been replaced)
Water pump replaced
No leaks
Thermostat is opening ( Upper hose gets hot, Lower hose stays cold for a while and then gets hot)
Flushed heater core with a garden hose.
Inlet hose to heater core is hotter than outlet hose but outlet hose is not cold to the touch.
Radiator cap has been replaced
Car does not run hot at all

I have a 2002 Ford Taurus. When we bought the car the heat worked fine. One day we went to turn the heat on and it would only blow out cool air. We replaced the thermostat and that did not work. The blower works fine it just doesn't blow any hot air out. Also, the driver side seat adjusting control went out. The seat will slide backwards and will raise the seat up and down, but when you try to slide the seat forward it just makes a funny sound. It was working fine and the other day I went to move my seat forward and it wouldn't go forward.

Yesterday driving home the heat/AC turned on full bore by itself and would only blow warm air. It will turn off. The rear control works correctly but the front will not blow cool air.

I have a 09 santa fe and it just started doing this. when we start it and let it warm up it will get the normal temp and will blow hot air but when we start to drive the thermostat goes back down to cold and it will blow cold air. I have had a problem similar to this before and taken it back to the dealership and they replace the same thing over and over. but this time its not fixing itself and it is staying like this. usually it will fix itself.

The rear vents in my '09 Toyota Sienna minivan do not blow heat, only cold. The vents up front work just fine, but when I turn on the rear heater (whether from the front controls or from the rear controls), my kids get iced. They never blow heat, even after long periods of time. (Also, the upper vents in the back do not blow strong, even on High, although the lower one does). I heard something about an interior heat sensor, and about blend doors.

2002 Echo, automatic, 190k miles, no troubles with it. My AC and Heat have always blown out the vents, regardless of the direction that I want them to come from. The dial that should send them through the vents, the dash, and at your feet doesn't really do that much to send the air anywhere except through the vents.

I have a 1990 E250 and the heat does not blow. I have only had the van a year and it somewhat worked when I got it, but at the end of least winter It stopped blowing. It does not matter what setting I have it on low or high. if I turn the defrost on and put my hand on the dash I can feel warm air but it does not blow. It is the same for the vent, I can feel warm air coming out but does not blow. Sometimes if I hit a bump it seems like it will blow a bit harder but not like it should. My question is, should I just replace the blower motor, or is there something else I should check first?

I'm thinking this is probably just the way they are, but I don't understand why........... I have a '12 F250 supercab 6.7 FX4.... truck is an XL, no supplemental heat or anything. If it sits outside over night, and I go out in the morning after say a 35-40 degree night, start it up and let it run 10-15 min then drive 5 miles down the road to town, both temp gauges are still pegged on the cold side, and there's virtually no heat blowing on the defrost. Even if it sits in the heated garage over night, same temp, same drive to town in the morning, same lack of any heat.
My old 2010 V10 that I traded for the 6.7, and my current 09 5.4 are the exact opposite of this. I can start the 5.4 cold, leave within a minute or two, and be making some heat within a few minutes. By the time I get to town, everything is well in the normal range, and I'm turning the heater down cuz it's too hot. Even once the 6.7 is fully warmed up the heater doesn't seem to make near the heat that the gas trucks do. I love the 6.7, I just find this a bit odd. Am I missing something, or is this just the way they all are?

I have a 2000 yukon and the climate control stopped working. The defrost works just fine but the heater/ac stopped working nothing blows out from my vents when ac/heater setting is on. I checked all fuses and wires and everything is ok and connected. I just replaced my cd player and the next day climate control stopped working. I went back and checked the wireing of the cd player as well, everything is fine. Would i need a new climate control, or senser or is there a fuse on the heater itself.

Problem: About 10 minutes after driving, the heat starts to blow out of the upper vents when the a/c is on automatic. The heat comes out even if the outdoor temperature is mild (55 – 70 degrees Fahrenheit) and the cabin temperature is warm, which heats up the SUV quickly making it very uncomfortable. Turning the a/c off tends to somewhat solve the problem some of the time, however, occasionally hot air creeps through the vents even with the a/c off. The a/c often makes a gurgling sound whether it is on or off. I noticed today (2/3/12) that the back vents are not affected by the problem, so the very warm air is only coming from the front upper vents.

I have a 2009 f150 fx4 it will not blow cold air or heat on any setting. I have replaced the resistor and it stopped working again if i smack the black box the resistor is in it will work again. My question is where is the blower motor and how hard of a job is it to change. I just ordered the motor.

I just recently bought a 2003 Pontiac Grand Prix GT V6 four door. After buying the car realized the dash and taillights were not working. I brought it back to the lot and they fixed the tail lights and dash lights. They said the box was just sitting on the frame and was shorting out wires but now was fixed.
Ever since this was fixed when I run the AC or the heat or defrost the car starts to struggle or jerk. Sometimes the Airbag light or the low oil level light will come on (the oil level is fine) and sometimes the gas gauge will drop a little, lastly it will sometimes stall when slowing down when pulling into a parking lot.
When I do NOT run the AC or heat the car seems to run and drive pretty smoothly in general. Yet sometimes I do get an air bag light come on or a little jerk when I slow down at the light or in a parking lot but nothing like when running the AC.
The mechanic at the car lot is stumped at what could be causing this. I think I need to find a new mechanic. What would be causing this? A sensor? The car drove fine until the dash and taillights were fixed.

Just had the truck in the dealership for a bad blend door/ heater core case. Heat would only blow out warm on the passenger side, blows cold on drivers side. Dealership replaced the case, heat works normal on both sides now. It was a little warm out yesterday so i turned on the A/C, frosty cold on passenger side, warm on drivers side, temperature does change when i select different temperatures (dual zone.)

My A/C works, blows nice cold air. As I am driving the fan stops blowing. The LEDs on the A/C panel are lit but no cold air. I stop the car, restart it and the air starts blowing again. Have you see this problem? What should I do to try and fix it? If there is a sensor will you send me a diagram of the location of the sensor?
