- Risk
- If this were to occur during bad weather, driver visibility would be reduced, which could result in a crash.
- Remedy
- Dealers will replace the wiper motor circuit board and cover. Owner notification began on june 19, 2003. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact chevrolet at 1‑800‑222‑1020, gmc at 1‑800‑462‑8782, or oldsmobile at 1‑800‑442‑6537.
Recall number 03V159000 · Recall details
Exterior lighting: brake lights: switch
- What is wrong
- Vehicle description: pickup trucks, crew cabs, utility trucks and sport utility vehicles. These vehicles were built with the polarity of the wiring for the zero adjust brake switch reversed from what was specified on the switch drawing. With the reversed polarity, the contacts in the brake switch can wear out prematurely. The brake switch will perform normally until the brake switch contacts wear out, resulting in loss of the brake lamps without any warning to the driver.
- Risk
- This would fail to warn a following driver that the vehicle is braking and could lead to a crash.
- Remedy
- Dealers will replace the brake switch and reverse the wiring.

Tread / tire separation big bubble in tire severe shaking / severe pulling thought my truck needed an alignment very very very bad.
Tire separation causing bubble in tire /causing shaking / pulling severely to right side.
Tires separating causing major bubble and pulling as well as shaking.
The windshield wipers worked after being manually "helped" since the time of purchase, but no longer. When I contacted gmc, they told me the current recall did not apply to my vehicle. I have purchased the circuit board myself and will now need to have someone install it. Recall needs to include additional VIN #'s. I was told by the gmc toll free number that it was not a "safety" issue, sorry.
With the cruise control on I encountered sudden unintended acceleration on two occasions once while the unit was activated and once while it was not.
Windshield wiper failure. Gm refused to repair under recall campaign 98v150001 stating recall voided after 70,000 miles. I guess the bard turns "good" after reaching the mileage?
Dt a recall was issued on automatic transmission cooling unit and lines, but this vehicle was not included in the recall due to VIN although it had the same failure as mentioned in the recall. Contacted gm, and they confirmed that recall did not include this vehicle.
Dt: the windshield wipers when turned will intermittently come on and off. Sometimes it has to be done manually, and sometimes they will not come on at all. This also happens when starting vehicle, but occasionally windshield wipers stop in the middle. Dealer replaced the windshield wiper motor. Then, received a recall notice for another vehicle, but was told this vehicle did not fall under recall due to t VIN.
Dt : windshield wipers work intermittently or they don't work at all previous recalls in 1998 and 2003 had the same problem. Gmc hotline said they called the dealership, and the dealership refused to do the recall. *ak *sb
