Infiniti Repair Questions? Ask a Mechanic for Answers ASAP
Hi There, I'm Clayso a certified master automobile technician with 30 years of
automotive repair and diagnostic experience.-From your description most likely the blower motor is the problem. The brushes in the motor that make contact with the armature are worn and when your mechanic taps on the motor the brushes make better contact and the motor runs. To verify this have your mechanic perform the following to check the Fan Control Amplifier or Resistor Block as you say.-
