1985 Mercedes 380sl control unit/ac/blinkers not working! Advice needed!

[linaz]

I just purchased a 1985 Mercedes 380sl, the ac is not blowing, non of the buttons on the control units are working. The power window is not working and the blinkers stopped working suddenly and when they stopped working, the speedometer stopped working too. Any ideas on how I can resolve these issues and what I need to get?

This sounds fuse box related, apart from the ac control unit which is known for breaking (look up on YouTube for how to repair). I'd start with testing the fuses and if they are OK, whether they are making a good connection.

Blown Fuse ?

Always start with the basics. Have you got a multimeter, fusebox first, then follow the wiring.
