A/C Fan won't turn off...ever

[LXL15]

Hey guys,

Today my internal A/C fan (the one behind the glovebox) just wouldn't turn off. I tried turning it off using the climate control (it's a Fairmont), turning the car off and removing the key. Nothing. It just kept spinning, blowing out warm air. The only way I managed to turn it off was by removing the A/C fuse from the engine fuse box. It just turns back on if I replace the fuse. It seems to be stuck on a minimum speed, as I can turn the car on and turn the fan up on the climate control, but it won't go below a speed of around 3 or 4.

Can anyone help?! It also makes a noise as if the blades are rubbing on something, so if I have to remove the unit to fix it, I guess that's okay, as long as someone tells me how to do it, if it's possible to do yourself.

Cheers,
Alex
