Hey guys, I'm starting to have another problem with my C220. In the relay box, I've noticed one of the relays, which I beleive is for the fan....and contains a fuse, it keeps blowing the fuse. I was wondering if anyone else has experianced this problem also and what generally causes it? I've changed the fuse in the relay now for the third time, and i'm starting to wonder if my relay has toasted out. Anyone know how to test to relay, or any idea's what's happnening? thanks
