Two problems related to warning light on have been reported for the 2004 Chevrolet Silverado. The most recently reported issues are listed below.
Air bag warning light occasionally started coming on. Took truck to several independent svc places. They said do not have computer reader for airbags. Light started staying on constantly. Took truck to dealers and they said because of liability, the diagnostics are $900 and could run another $1500 or more to fix problem. And, they wanted to keep truck. Truck is used daily for short runs and has a bunch of equipment on it that would have to be removed in order to leave it somewhere. Because of the staggering cost, and the inconvenience of having to off load the truck and not have its use and the lack of places to work on it at all, we have left it alone. I have driven vehicles without airbags over 3 continents and through jungles & all types of terrain over the last 40 years with out ever needing airbags. Now takata makes a safety device that can shoot and kill you -- do I need this? if so, who pays the repair bill?.
Recently while trying to start my truck there was a drivability issues with the powertrain, I had the lock light for the theft deterrent system on the instrument panel come on. The check engine light was also lit. The airbag light for the passenger side wouldn't come on. It read "airbag off" even though there was a passenger seated. The red warning light for the drivers side did not appear to work either. This issue only happened one time. Cw.
