Re: Tailgate on a 2002 trailblazer will not open. unlock...
- There was a Technical Service Bulletin concerning this.
- Bulletin No.: 03-08-52-002
- Date: March 27, 2003
- Technical - Subject:
- Remote Keyless Entry Inoperative (Reprogram Liftgate Module)
- Models:
- 2002-2003 Chevrolet TrailBlazer, TrailBlazer EXT
- 2002-2003 GMC Envoy, Envoy XL
- 2002-2003 Oldsmobile Bravada
- Condition
- Some customers may comment that the Remote Keyless Entry (RKE) is inoperative at times.
- Cause
- An anomaly has been identified with the software in the Liftgate Module (RKE functions). The Liftgate Module software is affected when the temperature is approximately 40°C (104°F).
- Correction
- Using normal SPS reprogramming procedures, reprogram the LGM Liftgate module. The information was released on TIS version 2.75 or newer broadcast in March 2003.
- There is a fuse block under the rear seat on the drivers side. Fuse # 3 and # ^ are the ones you will check for the Lift Gate.
- Often the problem can be in the harness going to the module.
- Sometimes the module needs replaced and then reprogrammed.
