Slow wipers & no blower motor in MM

[JesseOnABoat]

I have a 95 MM and I was driving the other day and all of my electronics on the inside (radio, cigarette lighter, blower motor, int. lights, etc.) stopped working. I started it up the next morning and it was all fine, except my blower motor, it was running extremely slow. then today I started it up and the windshield wipers were super slow & my blower motor didn't work at all. Anyone have any advice?

Measure the voltage to the blower and wiper motor when running. If less than 12v, check and clean the under dash ground points. The listed electronics may share a common ground and if it's poor, it will reduce power to whatever shares that ground point. Also a good idea to clean the negative battery cable where it attaches to the battery, body and block, and the ends of any other ground cables in the engine bay.
