You are talking about the radiator fans right?
Sounds like a bad relay. Find it and replace it.
Need help, woke up this morning to discover my fan running. I was in a rush so I took my bike(FZ1) and left. Got home and now I have to charge my battery. Before I pulled the battery I noticed both fans turning (slowly b/c the battery was very weak). Is there an easy fix such as a "relay or module" or am I looking at something more serious??
btw : its a 2.5 '06 jetta
