Owned my sporty for 4 years from 68k mi's to 140K mi.. I've disassembled my blower motor twice and regreased it with silicone grease. This will make it last for about 1-2 years.. and the noise will usually come back in the fall/winter. I had the same problem.. that spray stuff is not thick enough to hold. you need thick grease. If left neglected it will lock up.. consensation gets in the bushings where they should've used bearings like all of them should but don't. <img src="/forums/images/graemlins/confused.gif" alt="" /> Anyway, you've gotta bench grinder with a wire wheel then wire wheel the corrosion off the ends of the axle. grease it more than kia did to deter futur corrosion. I had trouble getting it back together with so much grease because it made an airtight seal on the lower bushing. I'd press it in and it would pop back out due to air pressure.. I just drilled a small hole in the bottom of the blower motor housing to release the air pressure. This also will be my way of greasing the lower bushing next time it acts up.. WITHOUT disassembling the motor. It's tricky to do with the contacts an all but it can be done. I did it twice <img src="/forums/images/graemlins/smile.gif" alt="" />
