2002 Ws6 Map Lights won't click on.
 

Map lights don't come on when either button is pressed under the rearview mirror. They do come on when the door is opened (they are programmed to fade, which works ok). They also come on when the interior light switch is rotated to the "on" position.... they can be clicked "off" at this point also. I checked voltages at the wiring connector (at the mirror) and it appears to be correct: 1 constant ground; 1 constant hot; and the third changes state. Seems like this is a goofy way for these things to work. One would think that they should click "ON" then click "OFF" by the push of the button under the mirror.
I cheched all fuses w/ volt-ohm meter and they seem to be good. I checked other threads and post but haven't read about this issue with others.
