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.

How it is said to have ended

  • says it came back2
  • says it did not fix it2
  • result not stated16

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.

    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.

    Oil Consumption Measurement and Loss of Oil Service Bulletin

    1. 1Fault

      Not stated

    2. 2Finding the cause

      Possible causes

      • Towing a trailer or hauling additional weight will increase oil consumption.

      Steps to confirm (in the document’s order)

      1. The accepted rate of oil consumption for gasoline engines in vehicles at or above 8600 GVW is stated as 1 liter (1 qt) within 400 liters (100 gallons) of fuel used.
      2. Inspect the oil pans, engine covers and the engine oil cooler for leakage, and inspect for oil leakage into the engine coolant.
      3. Verify that the positive crankcase ventilation (PCV) system is operating properly; blockages, restrictions or damage to the PCV system can result in increased oil use.
      4. Wait at least 15 minutes after the engine is shut off before checking the oil level, so most of the oil has drained back into the crankcase.
      5. Check the oil level and record the vehicle mileage, date and exact oil level on the bulletin's form, then make sure the oil level is at, but not above, the full mark on the dipstick, adding oil if necessary.

    GM Vehicle Wide Programming (VWP) Software Update Process

    1. 1Fault

      • Vehicle Wide Programming (VWP) is a new process to update software on GM vehicles.

    2. 2Finding the cause

      Not stated

    3. 3Correction

      Vehicle Wide Programming (VWP) is a new process to update software on GM Vehicles. It provides the ability via a single selection within Techline Connect to first identify which modules need updating and then proceed to updating affected modules (with some exceptions). The updating of modules is completed in parallel instead of the technician needing to update one module at a time. This allows a more streamlined approach for dealers and customers.

    Water or Ethylene Glycol in Transmission Fluid

    1. 1Fault

      • Water or ethylene glycol in ATF changes the friction of the clutches, frequently causing shudder during engagement or gear changes, especially during torque converter clutch engagement.

    2. 2Finding the cause

      Steps to confirm (in the document’s order)

      1. An indication of water in the ATF: ATF blowing out of the transmission vent tube.
      2. The ATF may appear cloudy or, with extreme contamination, look like a strawberry milkshake.
      3. There may be visible water in the oil pan or a milky white substance inside the pan area.
      4. Spacer plate gaskets appear swollen or wrinkled in areas where they are not compressed.
      5. If water is found in the ATF and its source is not identified, or a leaking in-radiator transmission oil cooler is suspected, a simple and quick test kit that detects ethylene glycol in ATF is available.
      1 more points

    3. 3Correction

      Repair

      1. If water or coolant is found in the transmission, all rubber-type seals, all composition-faced clutch plates and/or bands, all nylon parts and the torque converter must be replaced.

    Engine Oil Consumption Service Information

    1. 1Fault

      Not stated

    2. 2Finding the cause

      Possible causes

      • Towing a trailer increases oil consumption and may put it outside the normal accepted rate given for an unloaded vehicle in personal use.
      • On vehicles usually driven short distances, less than 8 km (5 mi), especially in colder weather, unburned fuel and condensation may not evaporate out of the oil, and the dipstick may show the level as over-full.

      Steps to confirm (in the document’s order)

      1. Inspect the oil pan and engine covers for leakage due to over-tightened, damaged or out of place gaskets.
      2. Verify that the dipstick tube is fully seated in the block.
      3. Let the vehicle sit for at least 15 minutes after the engine has been shut off before reading the oil level.
      4. Verify that the positive crankcase ventilation (PCV) system is operating properly; blockages, restrictions or damage to it can increase oil use.
      5. Do not test oil economy until the vehicle has accumulated at least 6400 km (4000 mi).
      1 more points

    3. 3Correction

      Repair

    Tire Radial Force Variation (RFV) Service Bulletin

    1. 1Fault

      • The most common ride concern involving tire radial force variation is shake on smooth roads at highway speed, 105-115 km/h (65-70 mph).

    2. 2Finding the cause

      Possible causes

      • Tire related smooth road highway speed shake can be caused by three conditions: imbalance, out of round and tire force variation.

      Steps to confirm (in the document’s order)

      1. With the vehicle raised, center the wheels on the hub by loosening all wheel nuts and hand-tightening them while shaking the wheel, then torque to specification with a torque wrench, not a torque stick.
      2. If light brake application increases the pulsation felt in the steering wheel, go to the brake-induced pulsation diagnosis in the Brakes section of the service manual.
      3. A reading of 35 to 50 Hz typically indicates a first order propshaft vibration.
      4. Generally a reading between 10 and 20 Hz indicates a tire/wheel vibration.
      5. If vibration continues after 10 minutes of driving above 72 km/h (45 mph), temporary tire flat-spotting can be ruled out.
      2 more points

    3. 3Correction

      Repair

      • If the radial runout of a tire/wheel assembly is more than 0.040 in (1.02 mm), match mount the tire to the wheel to get below 0.040 in (1.02 mm).

      Caution

      • On the balancer always center the wheel by the pilot bore; never use the hub-cap bore, since it is not a precision machined surface.
