CENTRAL LOCKING ELECTRICS 190E 2.6
 

Has anyone out there got electrical drawings for 190E 2.6 1990 covering the central locking system.
The system locks all doors from the boot, but the driver door lock only locks driver door, as if it does not power up the vacuum pump. It has worked on the odd occasion so i tried a substitute vacc door solenoid but no change. I suspect electrical connection or cable break down at the door shut.
Thanks for anything. Mawbs.

Under back seat is a module covered in foam. disconnect the electrical portion of it and let is sit over night. reconnect and it should reset memory. I just did it on my 300e and it worked. I am soooo happy just hope it works for you. Good luck
