The fan that blows either AC Cool or Heated air only works intermittently in the front area. The 2nd row or rear blower is not affected. Occasionally the AIR or Heat doesn’t blow when you start the car. Or, it sometimes will begin to work 15, 20 or 30 minutes after the car has been running and blow then will work. Other times, the blower works when turned on. The mechanic can’ duplicate the error. Any suggestions as to what the problem is?
Turn the ignition on so the dash lights come on.
Set the blower speed to high.
Reach under the passenger side of the dash, and with the handle of a screwdriver rap on the blower motor.
If the blower motor starts working, replace the blower motor.
