Front Air Bag Sensor Control problems of the 2004 Chevrolet Trailblazer

The contact owns a 2004 Chevrolet Trailblazer. The contact stated that the instrument panel has not worked since she purchased the vehicle brand new in January of 2004. The warning indicators are constantly illuminated. She took the vehicle to the dealer several times while it was under warranty, but they could not locate the failure. Due to the failure, she does not know how fast she is driving, how much fuel is in the vehicle, and cannot read the odometer. Recently, the headlights failed and she took the vehicle back to the dealer. The dealer charged $91 to diagnose the failure, which produced a failure code at the headlight low beam relay cluster switch. The dealer replaced the low beam relay switch and ignition switch, but the failure persisted. Now that the vehicle is out of warranty, the dealer has finally located a diagnostic code for the instrument panel failure. The dealer stated that the instrument panel cluster failed and would cost $600 to repair. The failure mileage was 9,000 and current mileage was 68,000. Updated 4/14/09 the air bag light illuminated.
