HI Ya'll,
As W140 owners, there are a lot of things that can go wrong and my PSE finally stopped working after some intermittent operation and final failure of remote door locks, trunk, and gas tank cover along with rear head rests, etc. But close assist is still working since the other pump is OK for now.
After researching the PSE here, I decided to disassemble to PSE unit and inspect it. I determined one of the electric motor stator brushes had completely worn out leaving the Cu spring as a temp electrical contact until it wore out too.
In a nut shell, I was contemplating just replacing the Johnson manufactured electric motor with another but it seems very difficult to find an EXACT replacement. The closest motor I found was Johnson HC683LG-011.
Without further ado, here's the W140 p0rn...with captions.
