E30 wiper switch question

[6670charger]

Just bought my 88 E30 a week ago. Seems as though the wiper switch has decided to say farewell. Wipers work in intermittent only, and only for a swipe or two, then nothing. I looked at German Auto Parts to look for availability, price, and part number. RealOEM says the part number is 61311377979. German Auto Parts doesn't have anything for my year. Rock Auto doesn't seem to have anything either. Found one on ebay. Any sources for these other than ebay and maybe the dealer?

I may have brought one home from Germany out of a junked 88-89 316 sedan. Not sure if that will work on the U.S. version car or not.

Thanks.

Ended up being the ground screw in the switch. Took the steering wheel and lower column shield off and discovered that the screw was only on finger tight, if that. Sprayed electrical cleaner into the switch and cleaned the screw and connectors really well. Everything works great now.
