View Full Version : heater blower speeds gone

10-29-2015, 04:13 PM
I have an 06 and I removed the heater/ac control cluster to have it sent out as it blows heat all summer etc typical problem .... The blower has lost all speeds except high very slowly over the last yr my, I decided to jump the blower motor to make sure it wasn't the switch going bad and make sure the blower worked on each speed. No go only high again and I pulled the insulation off and filter out but cannot see a board or more than two wires going into the blower motor. anyone have any info for me so I am not gutting the heater for no reason lol thanks.

Buy yourself a replacement resistor pack for your heater speed control. if you get high speed, then the odds are good that this part's builtin circuit breaker has failed. The Resistor pack is under the hood (at the top, towards the passenger side of the vehicle - assuming you are not in the UK or Austraila, where the drivers side is not the same as in the USA, and many other countries), where the air intake gets fed into the HEPA Cabin Filter.
