Pontiac Repair: air conditioner fan moter, gm cars, resistor

Question
my air conditioner fan moter under the dash will not come on i replaced relay still nothing i was having trouble getting it to come on before but i could wiggle the wires and it would come on

Answer
Hi Barry:

what model car is this? If if didn't work and you wiggled the wires on the motor and it would come on and you replaced the motor and it still doesn't work I would suspect a bad connecton at the motor or the resistor for the motor. on most of the newer gm cars the issue is with the resistor or the connections to the resistor. the motor draw so much current the burns up the resitor or the connector going to the resisitor. hope that helps you out. :)
