Question
hi  i have a MB 1995 c-220 doors won't lock automaticly
but air conditioning works fine.  suggestions  ?
thank you


Answer
Answer:
The A/C system uses engine vacuum, and is NOT connected to your central locking in any manner.

Your issue should be:
A bad fuse.
A failed Vacuum Element.
A failed Vacuum Supply Pump.
A broken vacuum line.
