Record by record
19 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.
Component named as the cause
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.

What the documents say to do
HVAC blower motor resistor module / connector overheatingRepair
- Dealers install a new blower motor resistor and resistor module connector.
- 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.

Heater-Vent-Air Conditioning Warm Air Blowing Issue
1Fault
- The customer may comment that the A/C blows warm or that A/C performance is poor.
2Finding the cause
Steps to confirm (in the document’s order)
- Before calling GM TAC for technical assistance, have the listed information available to help diagnose the vehicle.
- Record the A/C high and low pressures, high side sensor reading, A/C compressor duty cycle, refrigerant solenoid valve command in HVAC data (if equipped), outside temperature, humidity and vent temperature.
- With an automatic HVAC system, read with the scan tool the evaporator temperature sensor (if equipped), inside temperature sensor, outside temperature sensor and duct temperature sensor readings.

Repair
- On 2007-2014 Tahoe, Suburban, Yukon and Escalade with moveable glass always replace the defroster tab (GM P/N 25916031) and the power connector (P/N 12034110); on all other vehicles reconnect the original defroster tab.
- Remove the rear defroster power connector and crimp a new one to the feed wire; the proper connector, P/N 12034110, is in the Packard Electrical Assortment, Tray 18, Position 5.
- Prepare the surface of the used defroster tab and the defroster buss bar with fine grain (500 grit) sandpaper or Emery cloth.
- Wipe the prepared contact area with Kent Automotive Acrysol (or equivalent) to remove residual oil or dirt.
- Heat the new connector on the buss bar surface to be soldered, holding the connector and defroster tab in place with long nose pliers.
