Unhappy really messed up my car this time...

Alright, I need some serious help here...
1988 300E
Last Thursday I took all of my seats out to dye them over the weekend. I finished painting and put the two front seats in yesterday. The passenger seat went in fine and all of the seat movements worked. When I put the drivers seat in, i tried to move the seat back, but it only would go in one direction on all of the switches. I then unplugged everything then plugged it all back in and now NOTHING works. I tried this several more times to no avail. Eventually I just got frustrated and gave up. So I am trying to fix it again today but I'm not having much luck.

So far I've replaced the two front seat adjustment fuses. I then hooked up my multimeter to one of the motors and I did not see a change in dc voltage when I used the switch. So then I figured it must either be the switch or the unit underneath the seat that activates the motors. To figure this out, I swapped the passenger and driver switches and tried them both, but neither seat worked. So I put the switches back where they came from but I still can't get either seat to work.

My next option was that maybe the car didn't know that my door was open and so the seat wasn't moving. I tried to start my car, but now it won't start. Panicked, I tried to turn on the lights, but THEY DONT WORK EITHER!!! ARGHHH

I just checked and my clock stopped about twenty mintues ago when I did all of this.

If you have any ideas, please let me know because I want/need my car back.

Thanks in advance.

Is your battery still charged? Perhaps something shorted and drained the battery during work on the car. (and may still be shorted?) Good luck.

Check and see if your battery is dead. If it is, charge it. You probably have some sort of drain on the battery as opposed to a short.

After you charge it you can test each circuit at the fuse panel with the amp function of a multimeter. There are are several good posts on how to do this - search on "battery" or "dead battery."

If the battery is not dead, start checking the major connections.

Good luck.
