A while back my radiator pop. I replaced it with a new one but now my AC panel does not turn on at all and the fans as well. It drives perferct but when it sits on a red light it heats up till the car moves again. What can be wrong? Does anyone have suggestions?

 

If under dash heater blower does not turn on you may have a failed blower motor or blower switch. Check fuse 17 (under hood fuse box) for blower and blower motor relay (under dash fuse box).

Overheating may be due to open or disconnected thermoswitch A, failed radiator and condenser fan motors, or electrical fault.

Try removing thermoswitch A connector and shorting connector pins to simulate closed switch. If fans come on, thermoswitch A is bad.

Check for 12V to fan motors at motor connectors w/ thermoswitch A jumper in place. If you have 12V, bad radiator and condenser fan motors.

good luck
