I have a 2002 Focus that is giving off a burning smell whenever I run the fan. Initially the fan was only working only on 4 so after some research I determined that this could be caused by the blower motor fuse. I replaced that and the now the fan works on all settings, however, there was a plastic burning smell after I put it back together. I then read that the reason why the fuse could fail is because of debris in the blower motor. I took off the motor and cleaned out a bunch of leaves and stuff, reattached the motor, but I'm still getting the smell. I popped open the hood and I don't smell anything burning in there. Is it possible that the smell is coming from the motor blower and that it could be failing? Thanks for any feedback.
