My left front cooling fan only intermidantly works. If I gently smack the side of it with my hand, the blades will spin, and the fan works ok, but only for a while. The blades are attached firmly to the spindle on the motor. And likewise I can feel that the clip and washer are attached in place. But the whole intermidant thing is driving me crazy as you can imagine. My guess is that a brush or something else isn't making proper contact inside. A while back at Autozone, I saw cleaner spray that said it was safe to use on both alternators an electrical motors. Does anyone here ever used a product like this before? And if so, what were your results? Thinking back, it wasn't untill after I drove my car thru some semi-deep water that my washer motor, and this cooling fan acted up... -Robert vin 6585
