Hello. I'm new to this forum and am hoping for some helpfull advice. I have a 2001 Galant sedan, with a 2.4 engine.

My a/c works only now and then, when it does it's plenty cold. I've checked the fuse, ok, i checked the a/c relay and even swapped it with the horn relay (same numbers), seems ok. I checked the connection that tells the a/c compressor clutch to engage, seems ok. After checking all these things and cleaning the connections sometimes the a/c will work, sometimes not. My wife took the car to the mall today (in the 90's) and the a/c worked fine. When she was ready to come home, no a/c. This has happened several times. Any help will be appreciated. Thanks, Jim

 

hello again. i'd like to add one more piece of information to my post/thread. we've had a major (for us) heat wave for the last several days, in the 90's. it seems that when the car is used a lot during the day the a/c just shuts down, which it did again today. BUT, late this evening, and a lot cooler, i started the car up and the a/c worked fine again. this is without doing anything to the car today. Any ideas?

 

when you say it doesnt work do you mean that its pushing just hot air, or that it doesnt do anything at all?

 

if its just shooting hot air, it just needs a lil bit of a "boost" go to an autoparts store and get u some refrigerant and a hose(make sure u have a guage) and add some to your system. be sure not to go over 55-60psi on the low pressure side. the hose u buy from the autoparts store should only fit on the low pressure side. it is the smaller of the 2 fittings that come off ur a/c lines. start the car. run the a/c full blast on recirc and hook up ur hose with the can of stuff attached. then fill to said psi and u should be good. when it gets hotter out the refrigerant expands and it takes more to make the same amount of pressure as when it was cooler out. i used to work at autozone and this would happen all the time to the old peoples cars.

 

jason and TheEngineer: Right, when the a/c is not working it just blows hot air. I'll take the advice and get a can of refrigerant, etc.. I've done a fair amount of work on cars in my lifetime but never on a/c's. I'll let you know how it all worked out, perhaps in a week or two.
thanks, jim
