When I first start the vehicle, it sometimes takes the fan blower motor up to several minutes to turn on. It seems to work fine once it turns on. The time delay between when you turn the switch on and when the blower starts varies between 10 seconds and 4 to 5 minutes. Should I replace the switch? Thanks for your help.

Hi:
I recommend checking to see if the power is getting to the motor when this happens. It could be the motor, resister, relay, or the switch.
