The central locking system does not work from the smartkey nor from the interior buttons. The truck will not open with they key either. I replace the 20 amp fuse in the F62 space from under the rear passenger back seat behind the light. This did not solve the problem. I can hear the pump go on and off as I press the key but does not do anything. The headrests do not go down either when pressing the release button. Not sure if its a leak or not.
I have a 2003 Mercedes S500 my doors want lock/unlock also my trunk want open unless I open it with the key but I have to manly shut it I also notice my massage sits are not working and the back headrest isn't working can someone please help me out with these issues
Smart key won't open door, battery is fine. Can't unlock doors or trunk from switches inside. Blade key was working fine for several months, now would not totally release drivers door had to get roadside assistance to manually unlock.
I have the problem , remote will only lock drivers door but will not open it . passenger side only way to lock or unlock is by hand. The rear doors will not unlock but if you unlock them manually when you drive the car they will lock. Fuel door lock will only work to lock and will.not unlock. Can any one help with my problem?
Can the Bosch Vacuum Supply Pump which assists with closing the doors and head rest be repaired or must it be replaced.
System fails to close doors. Removing fuse will make it work again (for an unspecified time period)
My remote FOB will not lock or unlock my car doors
The central locking system does not work from the smartkey nor from the interior buttons. The truck will not open with they key either.
ITS A REOCCURRING PROBLEM, A TEMPORARY FIX FOR MOST OF THE SYSTEM IS REPLACING THE FUSE IF THE PROBLEM CONTINUES FOR ONE ITEM AND NOT THE OTHERS (I.E. THE TRUNK STILL DOESN'T WORK BUT THE DOORS DO.) THEN ITS USUALLY PRESSURIZATION ISSUE AND EVEN THAT CAN BE A SIMPLE FIX IF YOU CAN FIND THE AIR LEAK.
Auto assist door closing and locking stopped working. Truck has to be manually opened. Patched a leak in the line but still won't work.
It isn't fixed . Drivers door will not open no matter what I have to climb over passenger seat
