Golf Mk4 4motion 3 door
I've had a problem with my interior lights for ages and tried all the usual door mech fixes, ccm replacement, checking fuse 14 (and every other fuse on the board).
Both doors register being opened on the dash and the back seat courtesy lights come on/off with either of the doors opening/closing, no problems with central locking or power windows.
Pulling fuse 14 with the door open I can hear/feel the big relay clicking and the rear lights go out (obvs)
All bulbs have resistance but as I understand it they should be able to blow and the circuit should still function for the rest
Manually switching the front map lights and dome light has no effect, no glovebox or vanity lights, plus boot light
I have continuity in the switched live cables that run through the doors but no 12V at the socket behind either kick panel
I think I'm looking for a corroded junction of the switched live (red/blue) somewhere, is there a common location for corrosion? I was hoping to find something like these corroded joins https://forums.tdicl...26/post-4366502 but don't seem to have the same loom (tried both sides and they only have a single red/blue running to the puddle light feeds) - and looks the same as this post https://forums.tdicl...26/post-5318620
At this stage I'd be happy to take the dash out if I knew exactly where I was trying to get to, but would rather not just start un-peeling the Teva tape in the hope I might strike lucky.
Any tips welcome on where I could focus my efforts please as I've run out of ideas
