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 faultNoiseWarning lightCorrosion or rustLeakReduced brakingAir conditioning or heaterVibration or shudder

Record by record

45 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 came back3
  • says it did not fix it8
  • result not stated2

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 issuesTrailer brakes applied whenever headlamps or park lamps are on (brake controller jumper harness)2

  1. Manufacturer communication2000–2003 GMC YUKON ・ 2003-02-01

    Trailer brakes applied with lamps on / controller backlighting wrong: jumper harness differs for 2003

    1. 1Fault

      • With the headlamps or park lamps on, the trailer brakes are always applied, or the back lighting of the trailer brake controller illuminates only when the brakes are applied.

    2. 2Finding the cause

      Possible causes

      • The condition may be due to wiring changes in the vehicle electrical system for the 2003 model year.

      Steps to confirm (in the document’s order)

      1. Inspect the brake controller wiring harness jumper plugged into the vehicle relay block body, which is under the left side of the instrument panel near the left kick panel, behind a plastic cover.
      2. The 1999 through early 2003 jumper has a reddish/brown 6-way connector and a tag with the last four digits of the harness part number; a second design 2003 jumper may have a white plastic connector with part number 5418.

    3. 3Correction

      Repair

      1. When a brake controller with its jumper attached is moved from a 2001-02 vehicle to a 2003 vehicle, the jumper harness connector must be changed.
      2. To use a 12171982, 15366255 or 15086884 harness in a 2003 vehicle, switch the wires in cavities A and D.
      3. To use a 15085418 harness in a 1999-2002 vehicle, switch the wires in cavities A and D.

      Parts

      • The 2000 jumper harness is PN 15366255, with a pink/purple tag reading 6255.
      • The 2001-02 jumper is PN 15086884, with an orange tag reading 6884.
      • The 2003 jumper is PN 15085418, with an orange tag reading 5418.

      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.

    Trailer Controller Information 2000-03 - Chevrolet Suburban, Tahoe - GMC Yukon, Yukon XL Some customers may comment that when the headlamps or park lamps are on, the brakes on the trailer are always applied, or that the back lighting for the trailer brake controller illuminates only when the brakes are applied. This condition may be due to wiring changes within the vehicle electrical system for the 2003 model year. Inspect the brake controller wiring harness jumper that is plugged into the vehicle relay block body. The relay block body is located under the left side of the instrument panel near the left kick panel, behind a plastic cover. The 1999 through early 2003 wiring harness jumper that plugs into the relay block will have a reddish/brown 6-way connector and a tag with the last four digits of the wiring harness part number. Second design 2003 may have a white plastic connector with part number 5418 as well. - The 2000 jumper harness is PN 15366255. The pink/purple tag identifier is 6255. - the 2001-02 jumper is PN 15086884. The orange tag identifier is 6884. - The 2003 jumper is PN 15085418. The orange tag identifier is 5418. When transferring the brake controller with the wiring jumper attached from a 2001-02 vehicle to a 2003 vehicle, a change to the jumper harness connector must be performed. To modify a 12171982, 15366255 or 15086884 harness for use in a 2003 vehicle, switch the wires in cavities A and D. To modify a 15085418 harness for use in a 1999-2002 vehicle, switch the wires in cavities A and D

    Vehicle Lean Adjustment Preliminary Information

    1. 1Fault

      • The procedure is for diagnosing and correcting complaints of the vehicle leaning left or right.

    2. 2Finding the cause

      Steps to confirm (in the document’s order)

      1. Measure fender wheel-opening heights, front and rear, to quantify vehicle lean.
      2. The front wheel-opening height is known as P height, and the rear wheel-opening height is known as R height.
      3. P height and R height are the distance from the ground to the highest point on the wheel-opening, going through the center of the wheel.
      4. Before measuring, make sure the vehicle is on a level surface, such as an alignment rack.
      5. Before measuring, check the fuel level and add weight if necessary to simulate a full tank.

    3. 3Correction

      Repair

      1. If Z height is out of spec and the D height delta is greater than 1/2 inch (12 mm), adjust Z height until it is within spec and the P and R height deltas are less than 1/2 inch (12 mm).
      2. If adjustment is not possible, check the front eye of the rear leaf spring for matching color-coded tape or paint; both sides should be the same color. If not, switch springs side to side; if so, replace the leaf spring on the lower side only.
      3. If this is not possible, shim the body and/or pick-up box until the P and R height deltas are less than 1/2 inch (12 mm).
      4. After all adjustments are done, perform a front-end alignment and check headlight aim.

    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.

      • 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.
