Yea, don't play with it - it's fine the way the factory set it. LOL.

It's there cause the engineers were worried that since early BMW's (all e30 and a few e36's) use the switch to directly drive the motors (no "relay" is involved) that the contacts might arc (big electrical spark) so much that they might fuse together, and run the motor forever - or until fire, smoke or a dead battery.

Has anyone even had their window switch pop ever? Don't think so - I've never heard anyone mention it.

I've seen a couple melt but that's a couple out of thousands.
