2004 Chevrolet Trailblazer ProblemsCooling 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.
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.
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.
