Causes the technical documents say how to deal with (10)
HVAC blower motor resistor module / connector overheating
4 matching records
The terminal interface between the relay resistor module and its power connector may be unable to carry higher current for sustained blower operation.
Moisture and contaminants may enter the fresh air intake plenum and reach the module's circuit or corrode the terminals.
What to do
- Dealers install a new blower motor resistor and resistor module connector.
- Cut the wires back far enough to remove any melted insulation.
Hydro-boost brake assist and power steering share one hydraulic supply (four campaigns)
2 matching records
Some vehicles were built with an out-of-specification hydro-boost housing relief valve bore.
The hydraulic brake booster pressure accumulator may crack and separate from the hydro-boost assembly during normal operating conditions.
What to do
- Perform the "Power Steering System Test" found in SI and make any necessary repairs based on system diagnosis.
- To tell whether a 670 gear box is fitted, inspect the mounting bolts that attach the stub shaft housing; a 670 gear box has only 3 mounting bolts.
- The PI document instructed technicians to diagnose the vehicle using the Power Steering Test Procedures if an owner complained about difficulty steering during "parking lot type maneuvers"; if the vehicle passed this test, no work was required, as GM viewed this as a normal phenomenon.
- Dealers replace the hydro-boost relief valve.

Positive battery cable contact with steering shaft universal joint (Denali) - Transport Canada 2001092
1 matching record
The positive battery cable assembly could contact the steering shaft universal joint.
What to do
- Dealers inspect the cable routing and reroute if necessary.
- The cable is also inspected for wear and replaced if necessary.
Aftermarket part (not the vehicle as built): Fram G3727 replacement fuel filter connector - recall 06E-043
1 matching record
The connector on the fuel filter was not manufactured to Honeywell's specification.
As a result, the O-ring may not seat correctly on the fuel line.
What to do
- The part number (G3727), country of origin (Mexico) and the date code (e.g., X60031) are located on the side of the fuel filter.
- Honeywell notifies owners and replaces the fuel filters free of charge.
Engine fuel rail crossover tube retainer screws may break (5.3L RPO L59) - recall 04V-376
1 matching record
The engine fuel rail crossover tube retainer screws were not manufactured to specification and may break.
The failed screw was harder than specification; the over-hardening came from a conveyor in an induction hardening operation at the fastener plant stopping or slowing excessively, exposing the screws to the hardening for too long.
What to do
- Check for leaks: ignition ON with the engine OFF for 2 seconds, ignition OFF for 10 seconds, ignition ON with the engine OFF, then visually inspect for fuel leaks.
- Dealers inspect the fuel rail crossover tube and replace the retainer screws if necessary.
- Hold the fuel crossover tube retainer to the bracket on the fuel rail with locking pliers, using enough force to keep the retainer from moving without damaging any parts.
- Remove the fuel rail crossover tube bracket retainer screw on one side and dispose of it properly.

Parking brake linings worn out prematurely, parking brake does not hold (PBR single-shoe drum-in-hat)
1 matching record
ODI is aware of over 600 complaints of premature parking brake wear-out in all MY 1999-2002 C/K 1500 trucks, regardless of transmission type; most involved vehicles with 20,000-60,000 miles (= 32,187–96,561 km), or 15-41 months in service.
Most complaints (over 90%) concerned a worn out or inoperative parking brake system, usually discovered during a service visit or mandatory state safety inspection.
What to do
- On complaint vehicles examined in the field, wear occurred earlier and to a greater extent on the driver's side parking brake unit and was largely localized at the tip of one of the linings.
- Bulletin 01-05-26-001 "Park Brake - Low Effort Apply System Description" (Mar 2001) describes a park brake test procedure.
- A revised clip designed to exert less force on the shoe went into MY 2003 production and into the service part stream. Installing the newer clip and replacing worn linings has been shown to remedy the defect.
- The closing report lists a bulletin of Aug 2004 as 02-05-26-001B "Brakes - Parking Brake Shoe Retainer Clip Availability", announcing a new retainer clip service kit for DIH-equipped vehicles.

Rear seat audio and/or rear HVAC controls inoperative (replace the RSA, not the console)
1 matching record
What to do
- Replace the RSA.
Conversion equipment (not the vehicle as built): Southern Comfort running board courtesy lights overheating - recall 03V-094
1 matching record
The courtesy light or lights might overheat when the wire harness is exposed to excessive moisture and road salt.
What to do
- Dealers replace the wiring harness on these running boards.
Purge Solenoid: failed
1 matching record
Engine fuel rail pulse damper retainer clip may fracture (8.1L V8) - recall 06V-289 / Transport Canada 2006195
No matching record (stated by the technical documents)
The engine fuel rail pulse damper retainer clip may fracture, leaving the damper inadequately retained.
On certain vehicles, the engine fuel rail pulse damper retainer clip may fracture, resulting in inadequate retention of the damper.
What to do
- To inspect for leaks, turn the ignition ON with the engine OFF for 2 seconds, turn it OFF for 10 seconds, turn it ON with the engine OFF, and inspect the fuel rail, fuel rail dampener, and fuel rail pressure cap and valve for fuel leaks.
- Dealers replace the engine fuel rail pulse damper retainer clip.
- Dealers replace the engine fuel rail pulse damper retainer clip.
- Part: 12575017 Clamp-Fuel Pulse Dpnr, quantity 1 per vehicle.
