Hey everyone, I have a 2003 Mini Cooper, and I’m having issues with the cabin blower fan. When it is cold outside, the fan works, but when it is hot outside, the fan doesn’t work. It turns out, if I reach into the cabin airbox and give it a boost, it will start spinning again.
My guess is that the grease is old and junked up in there, and so when it is hot, it gets sticky and seizes up the motor. The main problem is on this year, the interior blower motor is only removable by taking the dash off and it is a big pain in the butt.
I want to ask if there are any recommended sprays or cleaners I can use on it without having to remove the dash. From the cabin filter airbox I can reach right into the fan’s axle.
