2003 Chevrolet Trailblazer Problems

Cooling Fan Clutch May Fail Causing Noise and Check Engine Light

The cooling fan clutch may fail causing excessive fan noise and/or the Check Engine Light to illuminate.

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.

Check Engine Light Due to Gas Cap Issue

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