Multiple failures on 87 420SEL

Greetings:

When I got my car back from the alignment shop (also replaced a couple of frontend parts + pwr steering pump) there were a bunch of items that didn't work- speedometer, dome light door switches (dome light won't come on when door opens- OK when turned on using the overhead control and curb lights work OK), drivers electric seat, central locking. Fuses check OK. Frt Pax seat OK. Vanity mirrors OK. Trunk light Ok.

Is there a common thread here? I can't see one based on the fuse box description.

I should mention that they had to jump the car a few times (one cell in the battery went bad) and don't know if this could have been a contributing factor.

Saw the thread on the early 80's speedo pickup check- is it the same in mine?

TIA for the help

Take it back to the place and make them fix the problems that arose when the car was there!

But what to check... hmmm, you've checked all fuses? Replace anyway, there can be hairline cracks in them. They are cheap so I'd replace them all if I were you.
Also, this sounds similar to some problem with my car after the fuse box had been messed with. One of the rows of fuses (of 3 on separate holders in fuse box) was not put back into place all the way, thus I lose a 1/3 of my power components, or everything that was fused in that row. Make sure it's they're all in tight, mine needed to be unscrewed.
