today i did not put the a/c at all cause the weather here in Houston was nice and the car did not overheat.
i dont know what is the problem.

 

It sucks driving in a humidity place and a/c not working. Can some one tell me what's wrong? Well the a/c does work but the car overheats. I check the fan and it on when the a/c is on so I really don’t know what it is.

 

iirc the fan has 2 speeds, 1 high and 1 low....so are you seaing both fan speeds
it's my understanding the high speed fan works when the A/C is off to help draw the air thru the A/C condensor and the radiator and then uses low speed fan when A/C is on
or vice-versa, I cant remember which but you get the picture, right

 

ok got ya so if u change the relay for the fan speeds u think it should not overheat if that's the problem and how much u think the relay would cost me?

 

Its the other way around, the fan kicks into high speed when the a/c is on to get more air threw the condenser.

 

well the relay for the fans is in the CCRM, so it could be the problem, we sell alot of them, what year is it

 

If the problem is happening whenever the A/C is on I would check the condensor. It could be icing up blocking air flow to the radiator causing the car to overheat. This is easy to check run the car with a/c till you see temp starting to rise higher then normal then wait and turn of car. check the condensor for ice if you see any that is your problem.
