Air Conditioning Issue

[matt1987]

On my 00' GP I'm having trouble with my a/c. What's happening is a variance of temperature from vent to vent. On the passenger side vents, the air is ice cold. by the time it gets to my side of the vents, it is luke warm. It blows just as hard as the pass. vents. Just not as cold. I already charged the system so there's plenty of r-134. I figured the pass. side air out of the vents is colder since it's closer to the compressor and components. Any ideas?? Thanks

Don't take this the wrong way, but do you have dual climate controls? It's a stupid question, but I've seen people overlook it.

If it's electronic dual climate, check my FAQ thread.

Sounds like the typical blend door issue. Check the FAQ..

Thanks. Does this FAQ apply to non dual climate cars too?? I don't have dual climate controls...

This is not enough freon. The pass side gets the air first.

There is a remote chance that it's another problem, but

doubtful.

BTW, I have 2 GP's a 97 and a 99 and both have the same problem.

Charged properly, they work fine but as soon as they lose some freon

the pass side is colder than the drivers. Both have small leaks.

I had a similar sort of issue, the issue was a mixture door that had, for some reason, jumped its hinge. Had to pull the heater core to get at the root cause of the issue.

 

One characteristic of a door that's jumped off the hinges is that, in the winter, the car just can't really get warm. This is because air from the cold side is always being dumped into the car through the door which should be locked completely shut.
