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:Lights (headlights, turn signals)Gauge or instrument faultSmoke or fireLeakNoiseWarning lightCorrosion or rustAir conditioning or heater

Record by record

26 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 came back3
  • says it did not fix it3
  • result not stated1

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 issuesDRLs or auto headlamps will not disable with the headlamp switch (Canada, RPO Z49; normal)1

  1. Manufacturer communication2003–2006 GMC YUKON ・ 2019-06-10(1 earlier editions of this document folded here)

    Daytime Running Lamps Will Not Shut Off in Canada-Built Vehicles

    1. 1Fault

      • Some customers may state that the Daytime Running Lamps (DRLs) or the auto headlamps will not shut off when using the daytime running lamp disable switch, which is part of the headlamp switch.

    2. 2Finding the cause

      Possible causes

      • Vehicles built for Canada (RPO Z49) have different software that does not allow the DRLs or auto headlamps to be shut off.
      • Canadian law prohibits disabling daytime running lamps (DRLs) or auto headlamps.

    3. 3Correction

      Caution

Known issuesVehicle body tilt or lean left / right (torsion bar front suspension)1

  1. Manufacturer communication2000–2006 GMC YUKON DENALI ・ 2017-08-15

    Vehicle Lean Preliminary Information

    1. 1Fault

      • The procedure is for customer complaints of the vehicle leaning left or right, whether the lean appears in the front, the rear, or both ends.

    2. 2Finding the cause

      Steps to confirm (in the document’s order)

      1. Measure the fender wheel-opening heights, front and rear, to quantify the lean.
      2. P height and R height are each the distance from the ground to the highest point of the wheel opening, measured through the center of the wheel.
      3. If the left-to-right difference in P and/or R height is 1/2 inch (12 mm) or less, no repairs are suggested because the vehicle is within specification; if it exceeds 1/2 inch (12 mm), follow one of the three diagnostics.

    3. 3Correction

      Repair

      1. Generally the stance can be adjusted with the torsion bar adjuster bolts.
      2. If Z height is out of spec and the D height difference is greater than 1/2 (12 mm), adjust Z height until it is within spec and the P and R height differences are less than 1/2 inch (12 mm).
      3. If adjustment is not possible, check the front eye of the rear leaf springs for matching color-coded tape or paint; if the two sides differ, switch the springs side to side, and if they match, replace the leaf spring on the lower side only.
      4. After all adjustments are done, perform a front-end alignment and check headlight aim.

      Caution

      • Before measuring, set the tire pressures to the pressure shown on the certification label.
      • Before measuring, check the fuel level and add weight if necessary to simulate a full tank.
      • The P and R heights are not set at the factory, and no specification is given for them.

    Remedy
    This Preliminary Information communication provides information to the technician about vehicles that have a lean to the left or right. Technician will need to measure fender wheel-opening heights, front and rear, to quantify vehicle lean. Fender wheel-opening heights are related to, but distinct from, trim height. The front wheel-opening height is known as P height, and the rear wheel-opening height is known as R height. Adjust and heights that are out of specification. After all adjustments are done, perform a front-end alignment and check headlight aim.

    Headlamp, Tail Lamp, License Lamp or Fog/Driving Lamp Damage

    1. 1Fault

    2. 2Finding the cause

      Possible causes

      • A variety of chemicals can cause crazing or cracking of the polycarbonate lens.
      • Bulbs with a higher output than original equipment run hotter, and the excess heat can melt the socket, housing or lens.

      Steps to confirm (in the document’s order)

      • Broken mounting tabs, rear housing fractures and loose components inside the lamp assembly are evidence of impact damage.

    3. 3Correction

      Repair

      • When servicing any exterior lighting assembly, transfer any electrical connection seals to the new part.

      Caution

      • Clean exterior lamps and lenses only with lukewarm or cold water, a soft cloth and a car washing soap.
      • Do not let a shop mat or fender cover drape over a headlamp while the DRL or headlamps are on; the lens may craze or deform.

    Exterior Lamp Condensation and Water Leaks Service Bulletin

    1. 1Fault

      • Exterior lamps such as cornering, turn signal, backup, head or tail lamps may show very small water droplets, a fine mist or white fog (condensation) on the inside of the lens.

    2. 2Finding the cause

      Possible causes

      • Condensation occurs when the air inside the lamp assembly reaches the dew point through atmospheric changes.
      • Non-OE lamps are most often presented as holding moisture or with inoperative bulbs from corroded electrical connections; they appear to be installed as part of a collision repair.

      Steps to confirm (in the document’s order)

      1. Normal: the mist is located mainly in the lens corners near the vents and does not cover more than half the lens surface.
      2. Normal: the moisture clears when the vehicle is parked in a dry environment or driven with the lights on.
      3. Leak: water has accumulated in the bottom of the lamp assembly.
      4. Leak: the condition will not clear when the vehicle is parked in a dry environment or driven with the lights on.

    3. 3Correction

      Repair

      • A condition covering more than half the surface of the lamp lens indicates the need to service the lens or lamp assembly.

      Caution

      • Depending on the lamp and the atmospheric conditions, the time needed to clear the lamp may vary from 2 to 6 hours.
      • If the normal conditions are noted, advise the customer that replacing the lamp assembly may not correct the condition.
      • Moisture that "comes and goes" is considered a normal condition.
