03 ML500 mirror turn signal doesn't work
 

My passenger side door mirror turn signal light doesn't work nor does my mirror adjustment for same mirror, also my rear quarter window doesn't open either. are these related in some way they all seem to have gone out at around the same time.

Remove the mirror and see if there are any broken wires. This happens with automatic folding mirrors.

The rear quarter windows are not connected in any way to the mirror. The only possibility that ties the two together is you might have spilled liquid onto the console or the sun roof was open while it rained.
