hi, i am new to this forum and any help would be appreciated.
i will post pictures of it later

i purchased my first sl 300, 1993 on saturday and it came with a few issues.

the doors do not lock or unlock,there was a key stuck in the drivers door barrel which i have removed, the key just turns and nothing happens.
i have located the pump but dont know where to go from there. near the pump was a lead with 2 connections , could be from the pump but i dont know where it goes?

also the roof light flashes once, no sound from the pump in the tyre well
and the roll bar does not do any thing
the fuses look okay.

many thanks
