My father's Mercedes Benz 124 E 300td from 1989 is acting up. My brother is on the MF, and the electrical stuff has gone really . Windows work only when door is open, wiper doesn't work (except some times on highest speed only) etc.

So I'm thinking, maybe there's a Mercedes forum just as useful and fantastic as my E34 forum, that may help my poor father and brother.

Any input?
