Q: heater fan wont work

asked by on

My car has an automatic transmission.

I recommend you request an electrical diagnostic on the blower motor circuit. It has to be determined if 12 volts is being delivered to the blower motor when the blower motor switch is on, in any or all switch positions. If 12 volts is not available to the blower motor, the circuit has to be traced to identify the open and/or faulty component such as the switch or fuse. If you request the electrical diagnostic, a certified Mechanic from YourMechanic will get this resolved for you promptly.
