Guys,
wanted to let you be a part of a hard issue i finally fixed!
Nearly a year ago my a/c stopped working the other day. Couple of frustrating tasks later i figured the fuse to be killed - worked with a replacement for a couple of weeks (i bought an automatic one, then ;-) ). Sadly, it jumped nearly every day the last months, not bothering me during the heavy bavarian winter... :cool:
After i figured that it was a spark going from the connector of the clutch at the pump i tried to check on this one, but guess what it was, after weeks of wondering and frustration? The cable going from the connector to the clutch, around a sharp edgy part of the pump. Everytime it touched the sharp metal of the pumps frame, it did a spark and killed the fuse. :eek: This cable is quite tiny and on the surface of the pump. You can see it when looking in from the top of the engine bay.
Solution: putting it a little away from the edge, and covering the whole thing with "Drei-Bond", a silicone that is like toothpaste to work with and ends up very firm like maybe you know from your bathrooms corners or the kitchen. You can get it from BMW. I munched it alle over the area, and since it got dried out my a/c is working like a charm. :biggrin:
Only for you guys maybe wondering why your fuse drops sometimes, maybe check on this one. Any questions? Having a diploma in a/c wiring and root cause analysis here ;-)
Cheers,
NeoP
