lately my car has been running kind of hot. It hasn't actually over heated yet but close. I don't remember hearing the fan come on lately either. How can I find out if that is what it is?

Hi:
The fan circuit is a simple design. The temp sensor sends a signal to the fan relay, and when the temp is above a certain point, the relay sends power to the fan motor. When the temp gauge shows hot, check to see if there is power to the fan motors. If there is, the motors most likely are bad. If no power, check to see if there is power in and out of the relay. If power in but not out, replace the relay. If no power to the relay, try the temp sensor and check wiring from sensor to relay.
