a/c-heat will only blow sometimes, mostly @ initial start up of car but even then only if you’re lucky ? Once it does blow air if you turn off or turn car off/on will not blow again till next day maybe or get lucky ? But when does blow it is ice cold or hot heat, research online says Power Module or probably Fan Speed Resistor, but need a pro’s advice ? Please HELP

  1. First thing I would test would be the blower motor. Direct positive and negative. Then I would use a scan tool to check for any codes with the body control module.

    Most likely the blower motor is going out.

    A quick test would be to check for power and ground at the blower motor when it is turned on but not blowing. If it is getting juice…. replace the motor.
