Hi everyone ,I have a 2007 CLK200 W209.
The switch on the dashboard that locks the 2 doors when you are sitting in the car has stoped working.
The unlock button works and the key fob locks and unlocks perfectly fine.Any ideas guys ?

 

Check the switch with an ohm meter!

 

Thanks will try,just don't know how to get the switch out without breaking it

 

I just fixed this problem buy replacing a door switch by the door latch . Push the button and see if the puddle light goes on and off to test it the car thinks the door is sill open.
