i have a merc WDB 220 167 - an S350 model with me

today i found the car unable to lock the car, ive check the fuses non is blown.

ive even get a friend who owns same model to try switch the pneumatic pump for the lock. still no changes.

ive diagnostic on the door and found

B1193 -componet S86 (servo turnoff micro switch cannot be close) or circuit to ground.

b1600 -component S87 stored 4s1 (servo lock micro switch) cannot be closed or short circuit to ground.


can you advice me what should i do next ? im confused...

So it doesn't work with the key or remote?

 

something is making the fuse 20A blown ...it work only a shot while then blown again ... seems like one of the lock is having problem/ short circuit .. going to investigate more...
