Hey guys! Recently been having issues with the blower motor on our 08 M2. When I take the green connection off the fuse block, it’s charred and burnt up, however cleaning the connection and putting it back seems to get the blower motor working again for a period of time. It can’t be a bad motor as we just replaced it
With a new unit. Any ideas on how to stop it from losing connection? Also why would the connection be blackened?
