Another LKM problem >with a twist

[piman]

Hi all,
The car:90 535i, auto
problem: no low beams.Hi beam work fine. I have tried the "well documented" resoder of the board. No dice. I can jump power to each light individually. Is there a wiring diagram on the net to troubleshoot this? Any help or advice would be awsome. Thanks in advance. Pi

by far i have no idea how to answer your question so ill through some **** out here...

Lets say the LKM *is* soldered and good, I believe there is a seperate fuse and or relay to fire the lights seperatly. Do a search on the very front page here, think its ...nevermind I cant find it.

in a perfect world you can taylor a search for "LKM" and "Javier" and you will find info.

no one ever archived Javiers LKM write ups so thats not an option. do a good search you will find what you need, ill look for some links for you.

headlights contact relay pins, but also on the corresponding LKM connector pins. Also check continuity for the relay coil, and condition of the relay contacts (clean and burnish if necessary).

E-mailed you a copy of headlights and LKM wiring for 1990.

Mine is similar to the one in the first post. Think I posted a picture some time ago.
