2008 Chevrolet Trailblazer Problems

Check Engine Light Due to Gas Cap Issue

Illumination of the Check Engine Light can be caused by a loose or worn gas cap.

Sticking Camshaft Actuators Due to Dirty Oil or Faulty Control Solenoid

The variable valve timing camshaft actuators may stick due to dirty engine oil or a faulty control solenoid. A sticking actuator may cause a rough idle and the Check Engine Light to illuminate. Our technicians tell us the engine oil should be checked to make sure it is clean and at the proper level before replacing any parts to correct this concern.

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.

Without a doubt this is the worst vehicle I have ever bought. In addition the chevy dealers are the most uncooperative people I have ever encountered. They either don't know or will not be honest about your situation. This car is a electrical nightmare.
