Thanks to all ...
Hi guys, thanks to all and this forum I've been able to fix my '84 325e by just reading.
Today it was just a problem with the windshield wipers not working (loose relay). The other was a starting problem that acted much like the main relay was bad and took me quite while to find and fix - turned out to be the "cam angle sensor"
Now if any of you can help me find a used housing for a Hella bumper mounted fog light I'll really be in 7th. heaven
Thanks again to all and this forum
