Print this page Notes: The 2002-2007 Chevrolet Trailblazer is known for many things, but perhaps it is most famous for its faulty fuel gauge.

This gauge flip-flops more than a politician during election season. Some report that the gauge says "empty" after a fill-up, while others report the gauge says "full" when they're running on fumes. Either way, there's one thing everyone seems to agree on: the darn thing is just wrong.

Following hundreds of complaints and a few accidents allegedly caused by the malfunction, the National Highway Traffic Safety Administration (NHTSA) opened an investigation into the issue in May 2011. Unfortunately for frustrated owners, no recall has been announced.

First my rear wiper and rear washer stopped working but when you turn the button it sounds like it wants to go. Second my speedometer is all over the board. Sometimes it runs low, sometimes it's higher and at times it just won't move. It has also been off the board pointer down at the prnd321. Third my oil gauge stopped working.

Fuel gage is not showing the fuel level, so it looks like its empty all the time automatic air bag passenger sensing system is malfunctioning and on windshield urethane bead may not have adhered to the body in certain areas during the cure process.

Saturday night (03/1/14) on our way home it started snowing heavily, the visibility was low and our windows were fogging up and the front heater blower went off on our 2005 Chevy Trailblazer and would not come back on. While trying to find a place to safely pull over we almost hit another vehicle because we couldn't see through our fogged up windows.. after we pulled over and turned the car off the blower motor came on and continued to run with the car off and the key removed from the ignition, so we re-started the car, and the blower went off and never came back on... then today I went out started the car to warm up the engine and the blower came on. I drove to the store shut the car off and the blower continued to run so I re-started the car and turned it off again and the blower motor stopped. When I re-entered the car to go home the blower once again would not turn on at any speed. So I figured if I didn't have heat at least I had a heated seat but after about 5-10 mins the seat part of the seat got so hot it was burning my butt and thighs so I had to shut it off. Then about 1/2 home the blower just started blowing again, I pulled into the gas station shut the car off and the blower motor once again continued to run with the car off and the key out of the ignition so again I put the key in started the car then turned it off again and the motor stopped. This could be a very serious issue with not being able to defrost the windshield/windows in these hazardous driving conditions< plus not having heat in below zero temps is a health hazard as well. ( since we live in such a cold snowy state).
