2005 Chevrolet Trailblazer Problems

AC Blower Inop Due to Failed Resistor

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.

Car wont start

My car's shifter is in the "Park" position, but the indicator on the dashboard says the car is in "Reverse." Because the car is not in Park or Neutral it will not start. I have already tried re-setting the ignition switch, but no luck

Faulty thermostat causing SES light to illuminate

This vehicle has a thermostat that fails in the open position which causes the temp gauge to drop below normal and heater to fail. The thermostat is located on the driver's side of the engine behind the alternator. You might need to remove the wheel to access the mounting bolts. You will need multiple rachet extensions and some patience. Dealer wants $500 to replace thermostat. Do it yourself for less than $100.
