A/C system failed one month ago. Took my car to the local repair shop and was told the compressor needed to be replaced. Had the compressor replaced, cabin filter all parts that were recommended. The cost of the job was $1,400.00

When I drove the car I noticed it took awhile for the A/C to cool the cabin as it was a hot day. But, after driving for over a half hour and even using max A/C I noticed that the air was cool but felt as if it was slightly mixed with warm air. I really didn't notice a difference between regular A/C and Max both on full cool mode. At some points the air actually began to feel more warm than cool.

Took the car back to the shop. They said refrigerant was at spec, and A/C was cooling appropriately. They said they added a dye to the system and upon inspection found no leaks. Several days later and I still don't concur with the assessment. I do have some mechanical skills and am a good observer of things (systems engineer). I know I am not imagining a problem. With the A/C on max mode and driving it for a period of time I would think it would actually make things very cold and it does not.

I checked the blend activator as described on your site and as I moved the control know from warm to cold and back again I cold hear the door moving. The only other noise I hear while driving is the fan sometimes makes a chirping sound. Not all the time.

So my question is where do I go from here? Is there a device with which to measure temperature at the vent? Is it possible the Blend Activator is not closing completely? I'm looking for information to share with the repair shop. I know if I go back again without a concrete issue I will be dismissed.

Your thoughts would be appreciated.

Do you
have the same problem?

This can be a couple of things, it may be the recirculation motor by not closing all the way when it is switched to max which it should. Try pulling the fuse -fuse 14 inside car for 60 seconds with key on it may reset the motor. It can also be a multiplex problem or control problem. Which for that will need to be scanned. It can also be what is called "freezing up" either due to moisture in system or junk in orfice due to compressor failure. For that all you need to do is see if your line going to evaporator (small to big) is all frosty and large line coming from evaporator is warm or sweaty. You can check that by opening the hood and it will show it when it happens. Also when a/c is on and engine warm make sure both fans are working, the one in front of condenser and one behind radiator. I f the condenser fan is not working then it's a cooling system problem with relays and fuses under hood. That will cause higher head pressure and not allow it to cool sufficiently. Also if you have one of those dandy "bug screens" in front of radiator or condenser, rip it off and throw it away because they stop 15% of the air flow and on hot days is when it is most evident.

Was this
