The vehicle (where a record says)

A record is under an engine, a drive or a series only where it says so: the characters of the vehicle identification number filed with a complaint, its text, or what its document says it applies to. A record that does not say is kept as "not stated". The filed numbers and the documents do not tell 4WD from AWD.

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.

What is needed

Parts and materials
  • New blower motor resistor
  • Resistor module connector (replaced even if it was replaced in an earlier repair)

Only what the technical documents state. "Not stated" does not mean not needed.

In the records

  • Blower Resistor: replaced 1（result not stated: 1）
  • Power Connector: replaced 1（result not stated: 1）
See the evidence (1 technical documents, 5 records)

Passages of the technical documents

  • The special coverage applies to 2003-2006 GMC Yukon and Yukon XL (and the other listed trucks) with manual HVAC (CJ3) or heavy duty heater (C42).

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

    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.

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

    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

  • The relay resistor module or wiring connector could overheat and the HVAC blower may not function on certain blower settings or may be inoperative.

    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.

A cause or a result a complaint states is the owner’s view or what a dealer told them, not an established fact.

Put together by FaultCrate from public records and technical documents. The cause and the repair are for the workshop to decide with the vehicle in front of it. Counts are records, not failure rates.
