Hi,
I've just bought a '00 MGM LS and I found some quirks in the controls and dash illumination - I will have them inspected by an electrician (who needs to convert the headlights to European beam pattern standards), but I just wanna pinpoint the causes before I get the job done:
The symptoms:
1) The dash control buttons, e.g. Rear Window Defrost, the EATC buttons, and the door-mounted seat controls, and the headlight (main lamp) switch) ARE NOT illuminated. They work fine, though.
2) The radio head unit display and buttons are illuminated and work fine.
3) The EATC display works, and the buttons are responsive.
4) The ashtray/cupholder drawer is not illuminated.
5) All other interior illumination (courtesy and vanity) works.
6) The door latch/window buttons on the doors are illuminated.
What gives? I read the wiring diagrams, though I'm unsure how the power is distributed to those components which are not illuminated. I thought they get power from their respective wire harnesses and connectors. Perhaps there is a faulty hot line before the voltage for the this illumination is distributed to the components, but I just don't know.
Could there be something unplugged? A blown fuse in the cabin fuse box or the battery fuse/relay box?
There's also non-stock wiring work, e.g. an additional 12-V cig-style power outlet in the right footwell; there are traces of a deleted phone/loudspeaker system and a mobile charging dock (some old Nokia, I guess). The LCM works fine. The headlights got the bulbs converted to some awful LEDs, which will be deleted and converted back to filament bulbs.
