Hi All

I have a problem that I think someone here may well be able to solve just by looking at the photos.

I have 3 bosch motors from a mercedes car, one from under the seat (adjuster) and 2 from the steering column (tilt and fore/aft)

THe car was flood damages and had salt water corrosion. I have had a few of these before, taken them apart, cleaned them up, lubes and reassembled them and they all seem to come back to life.

Hwever 2 of my current 3 wil not work. They seem to have some extra electronic hardware on them.

I have attached links to pictures of all 3 motors. PLEASE can someone tell me why they are not working and what I need to buy to fix them, I'm assuming the parts would not be expensive but the steering wheel motors are really hard to find. I have spare seat motors but the spiral cog at the end is geared differently plus the steering wheel motors have 4 wires connected and the others only two (i'm guessing to sense when end of travel is reached but thats just a guess)

I'm only am amateur at electronics (as you can guess) but ok with mechanical stuff. I would be so very grateful if someone can help me solve this.

note: working motor has circuit from power point to center contact at both positive and negative, non working motor does not have complete circuit, I'm assuming that to do with possibly blown component/s

pictures are below
