3-Series (E21, E30)Chat relating to the BMW 3-Series from 1975-1983 and 1984-1991 line. Specific models: BMW 315, BMW 316, BMW 318, BMW 318i, BMW 320/4, BMW 320i, BMW 320/6, BMW 323i, BMW 320i. E30 Family models include: BMW 325e, BMW 325i, BMW 325is, BMW 325ix.
Just recently, the dash lights in my '91 318is stopped working. When I pull the switch the exterior lights work fine but the dash doesn't illuminate. I've turned the knob but it's not a dim illumination thing. I've checked/moved all the 7.5A fuses to new positions with no effect.
The lights not working: main instrument cluster, heating controls, clock, rear demist button. The actual instruments, heater, clock, rear demist themselves work fine.
Any help gratefully received.
[Here in the UK we have speed cameras pretty much everywhere. So not being able to see the speedo is a real problem when driving at night.)
Wow, that's an incredible resource. I now know correct part no. & will confirm before bidding. Good idea to check the relay - I haven't a clue about this - where would I find it & what am I looking for! Sorry to be so dumb.
No problem! I was just as dumb two years ago when I bought my '90 325ic.
I just checked my notes and I mis-spoke. The relay I'm thinking of works the hazzard lights only. There is, however, a control unit relay for the interior lights. I could not find it's location though. It's $80.00. I'd definitely try a new rheostat switch like we discussed above.
The interior light relay is behind the front speakers. Changed mine a few weeks ago and now i have interior lights when i open my door!!!
and my dash lights stoped working a few months back and changed the
rheostat switch and all is good!!!
My hazzards and interior (door switched) lights are OK - it's strictly dashboard/front console that's the problem when I pull that little knob! I'm gonna change the light switch/dimmer assembly unit - sounds like that will resolve the issue. Thanks guys especially snpower for your time & advice - much appreciated.
