('86 325) Is the relay for the lock behind the driver side under dash, left side panel??? lime green??? and does the control unit accessible via the glove box have any control function regarding the electronic lock mechanism? Also the anti-lock break relay, where is that little bugger... I have a new relay (charcoal gray), but haaa.. can't find where it goes.... there are a lot of those color... tryin' to find one that matches the voltage & amp... oh where oh where does that little relay go....
I'm not sure where these relays are that you are looking for but I know an ETM (electrical troubleshooting manual) will tell ya! http://wedophones.com/BMWManualsLead.htm
central locking issues I just went thru cental locking issues(would not lock/ unlock). Relays are behind speaker grill driver side, below opening and held in w/ 2screws.The control for the locking system is about 6" by 3". My car(91) also had another set of relays on the same mounting bracket,not sure what they do. Problem turned out to be bad connection at door plug, also chk lock cylinder for broken tab.
