Does anyone have an electrical diagram that can share of the interior lighting circuit.
The most ridiculous thing happened yesterday... i went to change the interior light bulb on the roof. Put new globe in nothing. Put another in and still nothing. I went to check for power using the multimeter and accidently crossed the terminals very briefly (one slid across slightly while trying to hold them above head height), well there was power and ONLY the driver door light went out.
Long story short, the third light bulb worked!
But the problem is, when opening the driver door no interior lights come on. No key light, nothing.
Open the passenger door or hatch and all works as per normal. I'm like WTF???
Following diagnosis, checked the 20a fuse at the front and it's fine. Checked for shorts and continuity and I don't see any issues.
BUT... the driver door switch only has 3.5v going to it instead of the full 12v power (the passenger side has 12v). So I need to see where this wire hooks onto to get it's power from.
Is there an interior lighting circuit relay somewhere or a control box?
I have a feeling that either a relay or a control box is at fault here. I don't see a broken wire issue. This wire is getting it's source from somewhere perhaps a relay or a control box and I can't figure out why the passenger side is totaly fine which leads me to believe that the LHS and RHS circuits are totally separate from each other.
If I can get the interior lighting circuit diagram, I can figure it out from there.
