Re: Heater Blower problem
I have the same issue in my '04. Mine is a manual and I have noticed that when I put it in neutral to slow or stop, my engine speed drops below idle and lopes. My headlights dim as well. I am assuming that and the blower slowing or stopping is due to a lack of power provided by the alternator when the engine speed is too low. The only explanations I have found for this is a slow opening idle air control valve or small vacuum leak that won’t trip a code, but have not been able to check either of those yet. If anyone has more input, I would appreciate their input.
I have checked the blower resistor and noted the melted housing and arc damage at pin C, but that only kept me from opperating the HVAC in setting 1-3 since position 4 bypasses the resistor straight to ground through the switch. After reinstalling, the HVAC worked in all positions until pin C lost contact again.
