Hi everyone,
I'm a long-time reader, but first-time poster on the forum.

My Rear Window Defroster doesn't seem to work on my 1985 190E.
The light in the switch illuminates when I press it, and after 1min or so it starts to flash. Should that happen?
Eventually the light goes off and I can't feel any difference in Temperature on the screen.

This is the Rear Window Defroster switch, right?



Thanks for your help,
Tom
