The contact owns a 2003 Chevrolet Trailblazer. While driving 25 mph, the contact noticed that the fuel gauge was not registering the correct amount of fuel. Occasionally, the gauge would indicate that no fuel was present in the vehicle at all. The vehicle was not inspected and no repairs were made at that time. One year later, the temperature gauge, actuator on the air conditioning/heating system, and the speedometer failed. The vehicle was taken to the dealer and they confirmed that the actuator failed. The vehicle was repaired at the cost of $720. The manufacturer stated that no compensation would be provided because the failure was not under recall. The failure mileage was 30,000 and current mileage was 44,000. Updated 4/23/09 updated 04/28/09.

I have had the exact problems as stated in 10047425. Windshield wipers went out completely on a rainy day, module replaced, A/C broke on a hot day-fixed, power steering assist stopped working completely making driving the vehicle nearly impossible, vehicle started on reserve power when temp hit -6 degrees, heater motor stopped working completely the next day -10 degrees. Basically this vehicle doesn't like changes in weather.

My 11-month old 2003 Chevrolet Trailblazer has had multiple quality problems, twice affecting my safety. Most of the problems have been electrical in nature. The 4WD has become inoperable numerous times, once while driving in snow. In another incident during a severe thunderstorm at night the air conditioner (A/C) failed and I was unable to defrost my windshield in order to see. After one dealer failed to diagnose the 4WD problem, another dealer replaced my ignition switch because the technician said I had no power at all going to the "rear grid." I continue to have intermittent electrical problems, including near stalling at a traffic light, and ongoing 4WD failures. The car also has very jerky motion when in 4WD reverse, of course, when the 4WD is working at all. The dealer told me that was normal and now I see there is a service bulletin on the problem.

If the vehicle is turned on, when you turn on the A/C, the A/C pump will not turn on. You either have to turn the A/C knob on/off a few times to get it to go, or open the front hood, and tap on the A/C pump with your hand to get it to start. This happens at any point in driving or while in park. The A/C will not blow cold air unless you do as I have stated above.

Vehicle's dash gauges came on and speedometer started fluctuating after 35 miles driving and vehicle stalled out, not being able to restart. Computer was replaced by dealer. Problem arose again about a week later. GM had dealer replace another part in I believe the ignition key area. Check engine light came on again in a couple weeks and vehicle would not start for dealer after it was driven there. Dealer found wire connection in wiring harness to computer was not making continuous contact at a connection. Also dealer had to replace a switch when the A/C would work intermittently. Luckily I have a good efficient dealer and service department who cares about their customers.
