Hey my aunts TL overheats when she runs the AC.. Any ideas on what it could be??.. Input would be great .. Thanx in advance..

 

a/c fan not kicking on

 

have you done a radiator flush lately? i know mine was acting up a bit because didn't properly burp the system..

 

much faster to see if the a/c fans are coming on i bet they arn't if thats the only time the vehicle overheats, turn the car on turn the a/c on then go under the hood make sure BOTH are coming on if one is not check power @ fan (not the black wire) if you do not have power swap relay's/check fuses.
