Thank you so much I really appreciate the help! Ian

Thanks. I did as you advised and yes it works. So now back to my question. Any ideas where that wire might be going?

Hey thanks so much for the detailed replies. I hadn’t got back to this until today. So I cannot find a relay anywhere. You can see from the photo the three wires going into the back of the dash switch. Left : Br/vi this is hot wire middle : Br is ground Right: br/vi goes to ????? When the switch is set to ON the rocker joins the left hand wire (br/vi) and the middle (Br) which is the ground. The lights come on. When the switch is set to TIMER/DOORS the rocker joins the left hand wire and the right hand wire (both Br/vi) but the lights don’t come on, with door open or closed. I cannot find where this right hand wire goes, it vanishes into the abyss and I cannot find continuity with any of the other wires in the doors or the lights. Before I go pulling entire wiring harness apart, is there anywhere else I can look for the other end of this wire? Could there be a relay somewhere else? There is continuity between the door switch and the light. I ran multi meter between the two and continuity is there when door opens and not when door is closed. Don’t you love electrics

I’m now deep into this and can’t stop. I’ve checked everything and am down to it not grounding when the rocker switch is set to ‘Doors/Timer’. The elec diagrams say there should be a BR/RD wire going out to the Timer Control (FYI they name two different units the same which is very confusing). However I have two BR/VI and the BR ground. The light works when switched to ON / Steady but when on ‘Timer’ it doesn’t light with doors open or closed. It does light if I manually ground to the car body, but the door jam switch has no impact. As I cannot find a Timer Control or Relay in the car, any ideas on how this is wired? Where might that other Br/Vi wire be going to?

Thanks so much! Will keep trying to figure this out. Aftermarket alarm was added so that’s complicated things. I cannot find a relay or housing for one anywhere, unless it’s up where the CL unit is above the speaker. I’ve been trying to test the rocker switch and seems to be fine. Hopefully will narrow it down some more. Ian

Perfect that’s the info I was looking for!! Thank you! Ian

Thanks for the info and yes the car has an aftermarket alarm so hopefully that’s it. I will try re doing the connections and see. am still curious as to why I don’t have a relay for the interior lights or maybe it wasn’t standard?? Ian

As someone who bought a 528i recently with 29k genuine miles I can attest to the problems of a car not being driven. Haven’t had any major issues but it’s cost about €1000 so far to get it driving right. Will need 4 new tyres and electrics have lots of gremlins!! I still love it though bottom line : cars are deigned and built to be driven, not sit and do nothing!!!

I’m looking for some help with my 86 525e and the interior lights/door jam switches. Most information I have found online directs me to check the interior light relay but for the life of me there isn’t one in this car. I’ve searched and searched. Also it may have been removed as then wiring is a bit of mess for these lights down at drivers footwell and someone has done some odd things. if you think you could help or have a decent wiring diagram of these. Thanks Ian

Sent you message
