Low beams don't work

[imprttuner88]

Keep this short and sweet, TIA.

Low beams don't work. Swapped out switch and relays with known good parts, nothing. Fuse good. Can run a hot wire to the light and it works (just on all the time obviously). Anybody ever ran into this problem?

Car: '90 325i

Switch likely dead

Even if the swapped switch was from another car where it works, as well as mine works in the other car?

For some reason I glossed right over you having tried a switch. Check for voltage at the relay terminals for the relay coil when headlights are meant to be on. Do you have 12-14vdc at the headlight fuses?
