Thanks Hbofinger and Shaun (guest) for the detailed descriptor for the sun shade!

I have been searching and searching!

My 88 300 SE W126 has a factory installed power rear window sun shade that isn't working now, but apparently did when I first took it in to the mechanic.

It does slide up if I pull it and immediately retracts when let go. There is no motor noise when I press the button and I just changed ALL the fuses to bronze/copper.

My next step was to check the power to each fuse, as it was suggested by another forum to do so. I can't tell from the fuse legend which one it may be.

The other power items not functioning are: the passenger side mirror and antennae.

So from 2002 to 2014 ... the issue returns ... hopefully it will be painless, but it sounds like it will be painful to change ... OMG!!! But thank you for the detailed explanation!
