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.

Common on this vehicle:Gauge or instrument faultWarning lightNoiseLeakMisfire or rough idleAir conditioning or heaterCorrosion or rustVibration or shudder

Record by record

41 records state a cause or a remedy. Each record is shown as short labels in the order fault → finding the cause → correction. Press a label to narrow to the records that state it.

How it is said to have ended

  • says it was fixed1
  • result not stated5

A ribbon is as wide as the records that state both of its ends (only the commonest are drawn). A record that names several symptoms or components runs through each. Orange is records that say the fault came back or was not fixed. Results come from owners’ reports only; one that does not say is “result not stated”. None of this is a likelihood of a cause or a rate at which work succeeds.

Known issuesHVAC blower motor resistor module / connector overheating2

    HVAC Blower Motor Resistor Module Overheating

    1. 1Fault

    2. 2Finding the cause

    3. 3Correction

      Not stated

      What the documents say to do

      HVAC blower motor resistor module / connector overheating

      Repair

      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.
    Read the sentences of the record
    Cause
    On certain vehicles, the interface between the electrical terminals of the Heating, Ventilation, and Air Conditioning (HVAC) blower relay resistor module and the wiring connector (which powers the module) may be incapable of conducting higher current levels for sustained periods of operation. In addition, moisture and other contaminants (such as road de-icing materials) may enter the fresh air intake plenum and contact the internal circuit of the module or corrode the terminals. These conditions may cause the relay resistor module or wiring connector to overheat, causing various symptoms such as: the HVAC blower may not function on certain or all blower speed settings; a burning-plastic smell or smoke may be present in the vehicle, or; the HVAC blower may run continually with the ignition in the OFF position. These warning signs could, in certain instances, be leading indicators of an impending vehicle fire, which could result in property damage and/or personal injury. Correction: Owners will be provided with additional warranty coverage for the blower motor resistor module/wiring connector overheating condition. Under this "special warranty coverage", should this condition occur within 10 years or 240,000 km from first vehicle registration, dealers will install a replacement blower motor resistor and resistor module connector.

      2. Position the mounting/dismounting head so that the tire iron or pry bar can be inserted slightly clockwise of the sensor body when prying the bead up and over the head.
      3. Rotate the tire/wheel assembly clockwise on the machine when moving the bead to the outside of the rim.
      4. For mounting, position the mounting/dismounting head 180° from the valve stem and the bead transition area 45° counterclockwise of the valve stem.

      Caution

      • If the bead breaking fixture of the tire machine is too close to the TPM sensor or directly on top of it, it may hit the sensor as the bead breaks away from the rim, damaging the sensor so that it must be replaced.
      • Take care also when moving the bead to the other side of the rim: as the machine rotates and the bead is stretched around the rim, the bead can contact the sensor.
      • The sensor cap is aluminum and the valve is nickel-plated to prevent corrosion; do not substitute a cap of any other material.

    Tire Pressure Monitoring Issues This information applies to the 2000--05 Cadillac Deville, Seville, STS, 2004--05 Cadillac CTS, Escalade, SRX, XLR, 1999--2005 Chevrolet Corvette, 2004--05 Chevrolet Tahoe, Suburban, 2004--05 GMC Yukon, Yukon XL. If the tire machine's bead breaking fixture is positioned too close to the TPM sensor, or pressed down directly on top of it, it may contact the sensor as the tire bead breaks away from the wheel rim. This can damage the TPM sensor and require the sensor to be replaced. Also be careful when transferring the tire bead to the other side of the wheel rim. As the tire machine rotates and the tire bead is stretched around the wheel rim, the bead can come in contact with the sensor. - When separating the tire bead from the wheel, position the bead breaking fixture 90° from the valve stem. - Position the mounting/dismounting head so the tire iron or pry bar can be inserted slightly clockwise of the sensor body when prying the tire bead up and over the mounting/dismounting head. - Using the tire machine, rotate the tire/wheel assembly clockwise when transferring the tire bead to the outside of the wheel rim. - Position the mounting/dismounting head 180° from the valve stem. - Position the bead transition area 45° counterclockwise of the valve stem. The cap is aluminum and the valve is nickel-plated to prevent corrosion. Do not substitute a cap made of any other material.

      Refinishing Aluminum Wheels This bulletin updates General Motor's position on refinishing aluminum wheels. GM does not endorse any repairs that involve welding, bending, straightening o re-machining. Only cosmetic refinishing of the wheel's coatings, using recommended procedures, is allowed. Evaluating Damage In evaluating damage, it is the GM Dealer's responsibility to inspect the wheel for corrosion, scrapes, gouges, etc. The Dealer must insure that such damage is not deeper than what can be sanded or polished off. The wheel must be inspected for cracks. If cracks are found, discard the wheel. Any wheels with bent rim flanges must not be repaired or refinished. Wheels that have been refinished by an outside company must be returned to the same vehicle. The Dealer must record the wheel ID stamp or the cast date on the wheel in order to assure this requirement. Refer to Refinisher's Responsibility — Outside Company later in this bulletin.

    Chromed Aluminum Wheels Chemical Staining and Corrosion

    1. 1Fault

    2. 2Finding the cause

      Possible causes

      • Chemical staining mostly results from acid based cleaners; the stains are frequently milky, black or greenish.
      • A second type of staining comes from road chemicals such as calcium chloride used for dust control on unpaved roads, and looks like small pitting.
      • A third type results from prolonged exposure to brake dust that penetrates the chrome.
      • If the brake material sits on the wheel while exposed to moisture or salt, it corrodes the wheel beneath the chrome and leaves a pit or small blister.

    3. 3Correction

      Repair

      1. Remove heavy brake dust build-up with GM Chrome Cleaner and Polish, P/N 1050173 (in Canada 10953013).
      2. For milky stains from acidic cleaners, after washing and drying apply 3M Chrome and Metal Polish #39527 with a clean terry cloth towel; the staining diminishes as it is applied.

      Caution

      • Do not use cleaning solutions containing hydrofluoric, oxalic and most other acids on chrome wheels or any wheels.
      • Any wheel cleaner must be thoroughly rinsed off the wheel with clean, clear water.
      • Stained wheels are not warrantable; most acid based cleaners permanently stain chrome wheels.
      • This polish reduces the thickness of the chrome plating and, if used incorrectly or excessively, may remove it altogether, exposing a less bright, brassy coloured sub-layer.
      • For spotting from road chemicals the procedure may marginally improve the condition but will not restore the finish or remove the pitting.
