Power for rear pasangers make-up mirrors
 

Hello everyone,
I've searched this forum, but I can't find any relevant answer for my problem.
My car is 97 S500 (10/96).
The flip down make-up mirrors for rear passengers don't light up, when in 'down' position.
I've changed all four bulbs (two per mirror),
I've checked the small switch (multimeter), but still no light.:confused:
There appears to be ground on one of the wires, that come in to the enclosure, but no 12V..
How do these mirrors get power?
Do I need to turn the outside lights on?
Which fuse should I check?

My star DVD doesn't show a good picture of the wire routing and I don't want to mess with the roof liner...

Thank you in advance.

Check fuse 4 in the trunk

Dumb question, but I have to ask it. Did you test with the ignition switch on? I believe these mirrors only light up when the ignition is on.

I feel like an idiot,
When I took shower this morning I taught about the key in the ignition.
I went to the car and sure enough both the mirrors light up.
Thank you.


BTW bobs: How do you keep such a low millage on your cars? :)
