Light Control Unit
Hi All
I'm new on the list. I have a 92 124, new to me. I have been sorting some stuff out and had a very strange problem started just last night. My "light out" warning light came on, I checked and the RR tail light was out. Checked further - it was not the bulb but there was little or no power to that ciruit, fuse #3 was ok and all other lights on the circuit work. Checked up on the Haynes manual and it showed a "light control unit" that the lighting wires pass thru that also control the warning on the dash.
But this morning, the light worked again! Can someone shed some light on how this works and where this control unit is located? Is it as complicated as i think it is or is it a straight wiring from fuse to switch to light?
Thanks!

RE: Light Control Unit
Hi Sleepwalker
I have tested only until the light panel circuit board and the fuse. The wires go underground thereafter. Can you elaborate please on where the possible connections are? It was working again last night but I want to understand more because I'm sure it will happen again.

Hi Sleepwalker
It been working OK for the last 3 nights after cleaning all fuses and relays. I found the Light control unit too. Thanks for your help. If it really goes, I'm gonna need help again!
