2012 Fusion SEL 3L Auto, 64K miles
Blower motor for heater will sometimes work and sometimes not. It does not seen to be fan speed specific. When it does work, all speeds work. When it doesn't work, none of the speeds work.
While checking for loose wires, I found that when I wiggle the connector that the blower motor wires run into on the firewall, the blower motor will start. I also noticed that when the blower motor works and is on higher speeds, the connector that the blower motor wires runs into on the firewall is very hot, as in almost too hot to touch. Another set of wires, also in the same connector run off to somewhere else.
I disconnected the connector and removed the module that it was connected to. Rectangular box, aluminum heat sink fins on the back, 5 terminal for the connector with one being longet than the other 4. Lettered A,B,C,D and E.
Lots of numbers on the label,
Bought the car used and don't have a manual for it yet.
Would this be the blower motor resistor? My other cars never had automatic climate control, so it may be something more sofisticated than that.
Any suggestions on what to check to see why I get intermitant blower operation and also the very hot connector?
Thanks for any help,
