After starting my 2004 Chevy Trailblazer the gauges on the instrument panel did not work. But the ABS, seat belt, break and check engine lights are on. The indicator for gears is out. The speedometer jumps so not always sure how fast I'm going. I have only owned this vehicle for a short time. But after some research I have discovered that this is a very common problem with this vehicle.

My gauge cluster will intermittently stop working both while driving and while vehicle is parked and running. Usually after a few moments it would go back to normal but now the issue is getting worse and I have to tap on the gauge cluster for the gauges to resume working.this has been an ongoing problem since approximately 2006 but Chevy refuses to issue a recall on this issue which is in my opinion a safety issue

Oil pressure gauge drops to zero causing "check gauges" light to come on and engine to stall when the A/C is running and am stopped at a light in the city. This only occurs once during a trip or once a month. Understand that Trailblazers have a history of gauge problems and electrical issues. Chevrolet needs to issue a recall for electrical wiring/gauges.

When turning the ignition switch off from the run position while in park, the switch slips into the accessories position with no effort to turn the key. Truck will not turn off of assesoriy position until I wiggle the key for a while. The key can be removed after turning off truck but remains on assesory. Happens every time. Been doing this for a week now.[8-03-16 to present]

Upon starting the vehicle the instrument panel does not work properly. The gauge indicators all spike and do not accurately represent what is going on. For example it does not show how fast I'm going or how much fuel is in the vehicle. This is an extreme safety hazard.
