Need Advice on a few things
 

I have 1998 C230 Automatic.

1. My electronic seats don't always work. Sometimes they do and sometimes they don't. It's odd and I don't have the wiring schematic to figure it out. Any advice?

2. Power door locks don't work. I know it's possible that the vacuum pump is bad but I'm having a hard time taking out the bottom bolts or retaining clips that hold the bottom molding at the bottom of the fender. Any advice on this?

3. Does anyone have the OEM service manual in PDF format? Like the Bentley manual.

Thanks and Happy 5 de Mayo. :D
