Report A Problem

The AC/heater (HVAC) system may unexpectedly switch to the defrost mode when accelerating. This system is operated by engine vacuum and should be inspected for any vacuum leaks if this problem develops.  There is also a revised vacuum check valve available to address this concern.

On the 3.9L V6 and 5.9L V8 the engine oil leaks at the distributor can be misdiagnosed as leaks from the intake manifold seal, oil pan gasket, or rear crankshaft (rear main) seal. A revised distributor is available if oil is found inside the distributor.

Leak detection pump failure can be caused by the internal diaphragm switch sticking, or in some cases, contamination from debris or carbon particles from vapor canister. If black carbon particles are present in the LDP, replace vapor canister in addition to LDP. The purge solenoid should also be checked for debris or carbon contamination and replaced as necessary. All evap system hoses are subject to cracking and splitting causing leaks, Inspect hoses carefully. In cases of contamination from carbon particles or debris, all hoses and tubes must be blown out with compressed air to remove contaminates.

On 3.9L V6 and 5.9L V8 engines, the intake manifold gasket may leak and cause increased oil consumption and a spark knock during acceleration; the gasket should be replaced.

For the 9.25" HD Rear Axle only, some vehicles may shudder or vibrate on brake apply. This can be caused by axle shafts, brake drums, or brake shoes. A complete inspection of the rear brakes may be required to isolate the cause of the vibration.

Battery acid may leak onto an ABS wiring connector which could cause corrosion or a short circuit. A revised battery tray is available to protect the wire harness. Any damaged wiring will need to be repaired as necessary.

Some vehicles may exhibit a "buzz", whining", or "moaning" like noise from the transmission when reverse gear is selected. The condition is caused by a resonance of the transmission regulator valve. Our technicians tell us that the repair involves replacing the transmission regulator (aluminum) valve with a steel one.

The instrument cluster may work erratically at times. Our technicians tell us that the fault is commonly due to connection issues at the cluster electrical connector. There is a kit available to repair the connector and terminals.

Erratic operation of the keyless entry system may be caused by a faulty transmitter.
Our technicians tell us that some transmissions may exhibit harsh shift conditions or a false PCM codes P1763 and may benefit from a PCM software upgrade.
On vehicles equipped with a Theft Security system a loss of power to the Central Timer Module can result in a no start condition.
Intermittent cycling of the door locks especially during damp conditions may occur. Our technicians tell us that revised door and liftgate lock cylinder switches are available.
Side and rear cargo doors may open to far. New check arm pins, bumpers, and in some cases a new check arm are available.
The Central Timer Module may stop working intermittently causing various body systems to also stop working. There is a revised CTM available to that should correct this condition.
Problems may develop with the sliding door. Our technicians tell us that there is a revised latch assembly are latch rods available to correct sliding door latch issues.
