Question about 2004 Mercedes-Benz Mercedes Benz S Class

1 Answer

My s class 2004 mercedes wont lock. I try to lock it from the inside, it doesn't work. I press the remote, the light flashes, but it doesn't lock. When I drive; the doors doesn't lock like usual. The trunk wont pop open. The problem seemed to start there. I can only open trunk with key. The alarm went off when I opened the door. Is it a fuse?

Hi, if any doors, boot or bonnet is open it will not lock. there are SWITCHES that has to be set.for the system to recognize it is closed. please check all openings even windows. ONLY DO THIS IF.if the BATTERY HAS BEEN TAKEN OFF OR BATTERY HAS BEEN DISCONNECTED. the SYSTEM MAY NEED RESETTING. the battery NEGATIVE lead needs to be taken OFF and place the NEGATIVE LEAD ON THE TERMINAL (A NOISE WILL BE HEARD), the ALARM and CENTRAL LOCKING SHOULD BE RESET, if the ALARM DO'NT SOUND put the lead ON and OFF a FEW TIMES. CLAMP THE BATTERY LEAD CONNECTION TIGHT and press the ALARM BUTTON OFF and retry locking SYSTEM. this will work if everything is O. K. gerry

Transmission wont shift out of park


Try checking the brake light sending unit. Are your brake lights even working. Many newer vehincles will not shift out of park unless the brake pedal is depressed. However, a faulty sendind unit located on the pedal itself can keep you from moving anywhere. Just check to see if your brake lights are working to know if the sending unit is working.
