Fan Clutch Not Working?
I think my fan clutch may be shot. I can rotate it by hand when the engine is off, but it's pretty stiff. It doesn't free-spin. It blows air when the engine is running, but never seems to do a full lock-up and make a roaring sound. I ran the truck up to operating temperature and turned the AC on and off at idle and nothing. I never hear the roar of the fan being fully engaged. In fact, I can't remember the last time I heard it, so it's been a while. Last summer, the AC wouldn't blow cold air at idle. Freon level was low so I added some and its a little better. Wondering now if it was really a fan clutch issue, not cooling the condenser.
So far I've checked the plug and wiring. It's all there and hasn't been cut by the fan. When I get a few minutes I'l run an Ohm test on the plug to see it it checks out.
I'm still running the original fan clutch so I'm probably due. The online prices I'm seeing are shocking (around $400.00 for the part) so I'm looking for a less expensive source. I'd like to stick with the OEM but the pricing is beyond ridiculous. Does anyone have a source to pick up one for less. Any tips on diagnostics before get I too much further into this?
