2005 Chevrolet Trailblazer Repair and Maintenance

A guide to problems, costs, maintenance and repair for your 2005 Chevrolet Trailblazer

The fuel level sensor in the fuel tank may fail causing erratic fuel gauge operation. Our technicians tell us that on high mileage vehicles you may wish to replace the complete fuel pump module assembly if this condition occurs.

On certain 2005 - 2007 vehicles, General Motors has provided a special service policy covering the fuel level sensor, agreeing to pay 50% of the repair cost. This coverage extends for 10 years or 120,000 miles from the original "in service" date of the vehicle. Please contact your local GM dealer for more information.

The HVAC blower motor may stop working at one or more speeds due to a faulty blower motor resistor block. Our technicians recommend to confirm the resistor is at fault by first checking the operation of the switch.

I have owned my 05 Trailblazer since end of 2005 (I am 2nd owner). First few years no problems. Around 2009 I started having check engine light show up on a regular basis. Now it occurs about once every 6 months. Getting expensive to own! I have had electrical connection issues with the headlight (melted connectors), oxygen sensor failure (twice now), bad coils, broken plastic parts on the...

Well my trailblazer has done pretty good but, i've only had it 3mnths,and my check engine light came on and there has been a wining type noise in the engine.It acts like it doesn't wanna pick up speed.

We just turned over 79,000 miles and we've never had a single problem. We change the oil, oil filter, air and fuel filters but other than that we haven't had to do a thing. I had a 99 Ford Ranger before the Trailblazer and it was pure junk. I would highly endorse the Chevy Trailblazer.
