I just installed a newer General Module from a 1995 525i into my 04/1989 build 535i. It took care of my irritating lock/unlock twice routine, made the rest of the windows one-touch down (only), and a few of those other cool things the newer GM does. Shogun has posted several times in the past about the newer GM's so I have been on a search for the newest one I could find. Thanks Shogun...no denying you are a GURU!

Oh, the newer GM P/N I used was 61.35-8 355 818, the one that came out was 61.35-1 379 740.
