I had a problem with the air pump circuit one gren yellow cable was direct to ground. I toweed away the airpump with a new rollerbearing and left the rest out of function. Now all functions well appart the fans are working all the time. I don't know if it a problem of one of the 2 relais or preresistors.
Anyone an idea?

If you're talking about the twin electric/aux fans I had the same problem recently but not because messin with the airpump. As Dave/GSXR pointed out when i was having this problem, check the 2 sensors/switch that activates the fan - 1 on the intake manifold that triggers when the engine gets hot, 1 on the a/c reciever dryer bottle. Disconnect 1 at a time while the fans are roaring and see which one that stops them.
