:rolleyes: My blower fan worked loose with a loud whiz, sending small fragments of plastic through the vents. It had worked its way loose from the housing, but has now been put back in place (bayonet type fitting). The problem is that it now only works with the knob in position 4 (high). Is this more likely to be a problem with the fan itself or with the switch? or possibly a fuse or relay? Appreciate any suggestions.
