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:NoiseWarning lightGauge or instrument faultLeakCorrosion or rustMisfire or rough idleAir conditioning or heaterLights (headlights, turn signals)

Record by record

1101 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.

Symptom

Component named as the cause

Work done

How it is said to have ended

  • says it was fixed1
  • says it held for a while2
  • says it came back11
  • says it did not fix it24
  • result not stated39

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 overheating1

  1. Recall2003–2006 GMC YUKON ・ 2011-02-21

    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.

Known issuesHydro-boost brake assist and power steering share one hydraulic supply (four campaigns)1

  1. Recall2003 GMC YUKON ・ 2004-04-02

    Brake Hydro-Boost Housing Relief Valve Bore Recall

    1. 1Fault

      • The relief valve bore in the brake hydro-boost module may be out of specification, which could fracture the relief valve o-ring seal inside the module.
      • If the seal fractures, the driver may hear during braking an engine compartment noise like the one made when the steering wheel is turned to a full stop, and may feel slightly higher steering effort while braking and parking.
      • Under certain driving conditions a fractured seal may require slightly more brake pedal effort for the same deceleration, which could result in a crash without prior warning.

    2. 2Finding the cause

      Possible causes

      • Inspection found a machining error in the relief bore cavity of modules produced on one of the automated boring machines used for the base housing.

      Steps to confirm (in the document’s order)

      1. Look at the color of the relief valve: if it is metallic yellow or looks like brass, no further action is required.
      2. If a yellow, pink or white paint mark is visible, no further inspection or repair is required, and any stamped number is to be disregarded.
      3. With no paint marks and a stamped number 2, 3 or 4 visible, no further inspection or repair is required.
      4. If a stamped number 1 is visible on the machined surface, the relief valve must be replaced.

    3. 3Correction

      Repair

      1. With the ignition OFF, pump the brake pedal at least ten times.
      2. Unscrew the original relief valve from the hydraulic brake booster with the tool supplied with the new relief valve.
      3. Insert the new relief valve into the bore and tighten it to 17 N·m (13 lb ft).
      4. With the master cylinder mounted flush to the booster, install the nuts and tighten them to 33 N·m (24 lb ft).

      Parts

      • Part number 10398682, VALVE KIT, P/B BOOS CONT, quantity 1 per vehicle if required.

      Part numbers printed in the document

      The numbers are as the document prints them. The name and the replacing number are what the pages of GMPartsGiant, a reseller of genuine parts and not GM, state. Aftermarket equivalents are not checked here (the links only search by number). Confirm the fit for the vehicle (VIN) before ordering.

      Caution

      • Take care when working around the accumulator, which contains high-pressure compressed gas and hydraulic fluid.
      • Do not blow compressed air into the bore or flush the valve bore with commercially available cleaners; this could damage the booster or master cylinder.

    Read the sentences of the record

    From the manufacturer’s document

    • Applies to：The recall covers certain 2003-2005 Cadillac Escalade, Escalade ESV, Escalade EXT; Chevrolet Avalanche, Silverado Crew Cab, Suburban, Tahoe; GMC Sierra Crew Cab, Yukon, Yukon XL; and 2004-2005 HUMMER H2 vehicles built within the listed VIN breakpoints.
    • Condition：The seat loop at the second row center seating position may make it hard to position the lap portion of the safety belt low around the occupant's hips; in an accident a lap belt that is not low and snug on the hips may not restrain the occupant properly and could raise the risk of abdominal injury.
    • Cause：The 3-point belt for this seating position was designed and validated for the 2003 model year GMT800 utilities and crew cab pick-ups without a loop on the seat around the lap belt webbing.
    • Condition：GM states it is not aware of any incident in which this condition has been alleged to have caused or contributed to an occupant injury.
    • Repair：Dealers eliminate the seat loop by removing the safety belt from the loop and stitching the loop closed.
    • Parts：Obtained locally: upholstery thread of a matching color and an upholstery needle (size 16 recommended), 1 each per vehicle.
    • Repair：Remove the nut retaining the rear center seat's lower seat belt anchor.
    • Repair：Remove the belt from the seat loop on the front of the seat back cushion.
    • Repair：Route the belt outside the seat loop and install it on the lower anchor stud, making sure the belt is not twisted.
    • Repair：Install the retaining nut to the anchor stud and tighten it to 53 N·m (39 lb ft).
    • Repair：Sew the retaining loop closed in the center with upholstery thread and needle (size 16 recommended), using a minimum of four complete loops of thread.
    • Caution：A later dealer message reports that some technicians complete the repair with a sewing awl instead of a needle.
    Cause
    ON CERTAIN CREW CAB PICKUP TRUCKS AND SPORT UTILITY VEHICLES, THE 2ND ROW CENTER OCCUPANT SEAT BELT ROUTING MAY MAKE IT DIFFICULT TO POSITION THE LAP PORTION OF THE SAFETY BELT LOW AROUND THE HIPS OF OCCUPANTS, ESPECIALLY SMALLER OCCUPANTS, SEATED IN THIS POSITION. APPROPRIATE USE OF A CHILD SEAT OR BOOSTER SEAT, AS RECOMMENDED FOR SMALL CHILDREN, DOES IMPROVE THE FIT CONDITION FOR THIS USER GROUP. IN ADDITION TO INSTRUCTIONS ON PROPER INFANT AND YOUNG CHILD RESTRAINT (WITH CHILD SEATS OR BOOSTERS), SPECIAL VERBIAGE FOR RESTRAINING OLDER CHILD IS INCLUDED IN THE OWNER'S MANUAL. ALSO, THE SUGGESTED SEAT BELT FIT/ROUTING FOR ADULTS, IRRESPECTIVE OF SEATING POSITION, IS DESCRIBED IN THE OWNER'S MANUAL TEXT.
    Remedy
    DEALERS WILL CUT OPEN THE GUIDE LOOP, REMOVE A PORTION OF THE LOOP, AND THEN THE REMAINING TWO SIDES SHOULD BE FOLDED OVER AND SECURED WITH A RETAINER FREE OF CHARGE. THE RECALL BEGAN ON JULY 21, 2005. OWNERS MAY CONTACT CADILLAC AT 1-866-982-2339, CHEVROLET AT 1-800-630-2438, GMC AT 1-866-996-9463, OR HUMMER AT 1-800-732-5493.
    Consequence
    A LAP PORTION OF THE SEAT BELT ROUTING THAT IS NOT LOW AND SNUG ON THE HIPS CAN ALLOW THE LAP BELT TO RIDE UP ON AN OCCUPANT'S ABDOMEN INSTEAD OF FITTING LOW AROUND THEIR HIPBONES, AND THEREFORE, CAN EXPOSE THEM TO MORE RISK OF ABDOMINAL AND INTERNAL ORGAN INJURY.

    Brake hydro-boost module relief valve o-ring seal failure

    1. 1Fault

    2. 2Finding the cause

    3. 3Correction

      Not stated

    Read the sentences of the record
    Cause
    On certain vehicles, the relief valve o-ring seal within the brake hydro-boost module could fail. If this happens during braking applications, the driver may be able to hear an engine compartment noise similar to the sound that occurs when the steering wheel is turned to a full stop position. The driver could also experience a slight increase in steering efforts while braking and parking. Under certain driving conditions, a slight increase in the applied brake pedal effort may be required to achieve the same vehicle deceleration rate as prior to the seal failure. Correction: Dealers will inspect the hydro-boost module, and replace it, if necessary.

    3. 3Correction

      Not stated

    Read the sentences of the record
    Cause
    On certain vehicles, the 2nd row centre occupant seat belt routing may make it difficult to position the lap portion of the safety belt low around the hips of occupants. A lap portion of the seat belt routing that is not low and snug on the hips can allow unfavourable occupant kinetics in the event of a crash. Moreover, the higher routing allows the lap belt to ride up on an occupant's abdomen instead of fitting low around their hipbones, and therefore, can expose them to more risk of abdominal and internal organ injury. Correction: Dealers will modify the guide loop.
