No matter what button i press on the a/c controller, for like defrost, a/c, recycle, and the other buttons the air stays the same and always blows warm. Anybody know what i'm talking about or know the problem?

 

Sounds like you have a leak and lost all the freon. Have an A/C or radiator shop take a look at it.

 

Just wondering do you have the auto control or the manual controls?
for mine--when the days are not too warm or cold, the unit does blow out warm air but otherwise it works very well.

 

Sounds like a compressor. I had a lincoln that blew hot air and they had to change the compressor and the cluch fan.

 

if u have the warenty go get it fixed for free

 

There are a bunch of things this could be...

Turn the car on, turn the A/C off (or atleast put it on econ mode), role down the windows, and then hit the A/C button.

If you hear the compressor engage, and you can see a drop in the RPM (and then a rebound) then you atleast know its not the belt or compressor clutch. If this doesn't happen, then that's most likely the problem...either that or something as simple as a blown fuse (or something else in the electrical system).

If the compressor does engage, yet warm air is still coming out of the vents, its most likely either the compressor, or something has gone wrong in the refrigeration loop (maybe the expansion valve or something is clogged elsewhere in the loop). As long as the engine does not overheat, you can pretty much be sure its nothing wrong with the radiator.

Can you change where the air comes out of the blower? (ie feet, face, defrost, etc)

 

I think our car uses 134A?

 

R-134A is a common refrigerant used in automobile A/C systems...I think you are correct.

 

R134a = Freon There are many types of Freon on the market. R12 -(which is not produced but IS available) R22, R134a -(soon to be discontinued also) R502, and the list goes on. They vary in pressure ratings and chilling capacity.
