Interior light not working
#1621695 (In Topic #221914)
Any help much appreciated
91 MK1 cabriolet clipper.
The Light is powered off of the F3 (15A) fuse on the red wire 12V+
The grounds which are wonky as they run up from the door switches and are a Itty-bitty wire can get disconnected (brown/white) there are 2 wires on the Drivers side one for the seat belt, and one for the light.
So if you jumper a ground (earth) to the lamp 31or tk it should light.
I would suggest that you carefully remove the door switches as it is but one screw, and (I SAID CAREFULLY) remove the switch from the door to verify that the wires are still attached to the switch, and it wouldn't hurt to Polish the Plunger (remove the tarnish) tighten the Crimps a bit and replace.
The wires feed up the "A" Pillar from the Knee-bar access.
So I suspect that you don't have 12V or you have a bad fuse, as some after market Radios use separate fuses, it may be that your Radio isn't wired to F3 so check that with a meter…
Also on the window control module there is a Brown and White wire that feeds from the door switch.
If you cut that wire at the controller you can then roll up your electric windows with the key out and the door open for about 15 minutes, and never have to worry about having to re-insert the key and to run if you left your windows down…. (free gimme).
