My A/C works well when on normal and high for the fan speed. When I put my ac on "MAX AC" High fan, It begins to get very warm! The driver side vent is always warm, the pasenger vent is the coldest. Does anyone have any idea why??? somedays it wont work at all, others it works great but only on normal AC like I said. I have been strugling with this AC for about a month. It would not work at all for about a week, I finnaly found a napkin had wedged itself into the intake vent from the glove box, that helped alot but it is still warm somedays and I am having the problem with MAX A/C if anyone has any sugestions I would really apreciate it. Thanks all

Maybe you need a charge?

Maybe your control switch? Or like Ray said, a charge? or Have you tried searching for a leak?

Ray, thanks for the heads up, I usualy include the car info.

anyways

1995 GL ATX 2.0 with about 100,000 miles.

I havent checked the charge on it yet I am going to come monday. Thanks

The only difference between A/C and MAX A/C settings is that in MAX A/C, the inside cabin air is recirculated instead of being drawn into the cabin from the outside via the air filter.

If the normal A/C setting works properly, then there is a restriction in the air plenum located behind the glovebox. I'd suspect that more than one napkin was injested..

If the normal A/C setting does not work properly, then there may be a problem with either the temperature blend door or (more unlikely) the refrigerant charge. Since you described that the system does, at times, work well on A/C, I'd suspect a temperature blend door fault.
