You know i would think there is a fuse to the fan that would stop it from working though I have no idea which it is since I lost the relay card that was with the car before I had possessed the car even 12 hours; getting to the fan and disconnecting the wires is not that difficult, though involved; first time through expect a couple of hours, make sure you have a place to lay out the parts in order with screws; once the fan was exposed I used a strong pick to hook the hole on the clamp and release it/a large screwdriver to reclamp; what I did was, very carefully with patience, so as not to damage the plastic fan wheels, put the motor in a vise and with the red extension that comes with a can of WD40 sprayed it in and around the bearing; the shaft goes in a bearing which sits in a lipped housing; that did not free the shaft from the bearing, so with a sharpened screw driver I gently notched the bearing housing and the lip so that I could hold the bearing and lip and gently, with vise grips work the shaft back and forth, lubricating as I went until it freed up; someone posted a procedure for removing the plastic fan wheels, but I was not gutsy enough to try; I used to have something called Aerokoil that was great at freeing up parts rusted together, but cannot remember where I got it, think it was mail order from Kentucky; after freeing it up I applied power using a small battery/could use a battery charger, let it run, lubed some more, let it run, then applied some white silicone grease to inhibit corrosion, let it run then reinstalled and it works now; hopefully it will last through the winter; I hope this helps; once I had it out and was working it free I realized that part took me a good hour and a half; go slow, patience and take care of the plastic wheels.
