Question about 2003 Chevrolet TrailBlazer
2003 Chevy Trailblazer. How can you tell if the clutch fan is bad because I'm able to stop it with my hand. The rear heat/ac don't work and the front only works on speed 3, could this be a resister?
The fan clutch isnt engaged at all times, therefore it may be normal to hold it in place (not recommended). On these trailblazer's 4.2L engine the fan clutch is electronically controlled. Usually when this vehicle's fan clutch malfunctions, there is a random ticking noise while idling or at a stop, also the "service engine soon" may turn on. As for the the fan speed problem, this may be a faulty blower resistor malf (typical) or climate control unit may be faulty. Hopefully this helps!!
