OK I just bought a 97 rs camaro it had overheating problems ..
I have ruled out waterpump (flowing well) i dont think theromostat is installed as radiator flows all the time.. replaced the temp sending unit just below the throttle body. replaced the rad cap... ok the fans will not run unless the ac or defroster is on ... where should i look for the control that will allow the fan to run without ac or defrost on.. if i run ac or defrost the car will not overheat and stays right around 180.
