Decreased blower efficiency. - Visitor
I just picked up the vehicle at body shop having the front bumper repaired. Turning on the air...
Does the A/C Blower have a fuse, relay or resistor that would keep it from blowing? Where is it...
has the blower motor gone out?part # 1408300508 or is there something else wrong?
