The wife’s Mini overheated in a food line. The electric fan did not kick on. I think it leaked out of a connection rather than head or blowing the coolant bottle. I have checked everything and it looks normal. The connector is corroded so I cleaned it up and put some dielectric on it. I use a program that can activate the fan and it’s working now.

but what is this connector? It appears to be part of the fan harness but I cannot find anything it should connect to?

thanks for any help



What is the smaller connector?

 

Late reply, there is two variants of these cars. The small two pin connector you have off the fan is for 02-04 models. From my knowledge this connector triggers the high speed fan, which would seem accurate in your case. Low speed worked, until it couldn't keep up the car started overheating without stage 2 of the fan kicking in.

Whereas, facelift 2005+ models have the single large connector. These fans have the relay built into the fan assembly thus eliminating the second small connector. It would seem you have a facelift model, and need to acquire a single connector fan assembly and toss the two connector version you have.

Hope that helps

 

The switch was in April 2003. My car's production date was April 13th 2003 - Don Adams' birthday - and it has the single 3-wire plug....

 

Wow its interesting they changed it before facelift model. Great fact! Curious what drove them to change it during a current run.

 

there were a number of small changes before the "facelift". Some features in the body control modules, for example, improved with time, allowing more programmable goodies in NCSExpert. Sadly, lane change "trippelblink" didn't arrive until R56 timeframe. Euro double-blink hazards also not a thing in April 2003 units....
