Chevy trailerblazer fan overspeed sensor
Electrical problem
2003 Chevy TrailerBlazer V8 Two Wheel Drive Automatic 55000 miles
I have taken the vehicle to the dealership numerous times. They've changed the fan clutch, pulleys and supposedly even the wiring harness to the sensor, but the check engine light still comes on. I have the code check and it is the fan overspeed sensor over and over again. The fan makes a roaring noise from time to time and it goes away when I gun the engine in neutral. What would you suggest?
