FaultCrate・GMC Yukon 2000–2006・Air conditioning or heater

Candidate cause (the documents say what to do)

HVAC blower motor resistor module / connector overheating

The terminal interface between the relay resistor module and its power connector may be unable to carry higher current for sustained blower operation.

Moisture and contaminants may enter the fresh air intake plenum and reach the module's circuit or corrode the terminals.

What to do

  1. Dealers install a new blower motor resistor and resistor module connector.
  2. Cut the wires back far enough to remove any melted insulation.

Caution: The connector must be replaced even if it was replaced in an earlier repair.

In the records

No record states work done for this cause.

  • the interface between the electrical terminals of the relay resistor module and the wiring connector that powers the module may be incapable of conducting higher current levels for sustained periods of blower motor operation.

  • In addition, moisture and other contaminants may enter the fresh air intake plenum and contact the internal circuit of the module or corrode the terminals.

    General Motors (filed with NHTSA) 2012-01-01

  • If any of these were to occur, the relay resistor module or wiring connector could overheat and the HVAC blower may not function on certain blower settings or may be inoperative.
