I have an 05 VIII and i was driving it yesterday and when i got back and shut it off the front fan on the radiator, the one you can see through the front grill, wont shut off. I let it run thinking it was normal but an hour and half later it obviously wasnt. I disconnected the battery and obviously that works but as soon as i reconnect it turns back on. Any thoughts?

 

The one in front of the radiator is the A/C fan. The one closer to the tranny is the Cooling fan. I'm not sure, but that fan may be controlled by the same module possibly. If it is, its the piece the is bolted to the fan in the engine bay.

 

Yeah they're both controlled by controller on the radiator fan, but disconnecting it from there doesn't really do much for it. They have to disconnected directly, then some how magically work again after awhile when reconnected. Could try ordering another fan control module but they short out quite a bit. I just leave mine disconnected since I don't really run my A/C.
