s500 KEY (UNLOCK DOESNT WORK)
 

Hello, I have a 1995 s500.

PROBLEM: When I press the unlock button to unlock the doors, nothing happens. I changed to a brand new battery and still have the same problem. Where is the fuse for the locking system in the car? I checked all the fuses in the trunk and they are all good. Would the fuse be in the front hood for this mechanism?

run the CL funtion tests, will it lock? Does the trunk mounted IR reciever flash when your back there? Does the light on the remote come on when you press and hold the button? Does central locking work via the key on both front doors?


This could be a bad ir reciever, bad remote, door latch, cl pump and on and on, you need to isolate it more finely. The basic funtion of cl should be in the owners manual, (I might be wrong) run through ever function the owners manual has and see what it wont do, that'll help narrow it down.

Alright.

Also, I have to unlock the door manually and IT HAS to be from the passanger side because the driver side doesn't lift when I put the key in there. And when I unlock the key from the passanger side, the driver side is still locked and so are all the other doors. So basically it is a headache having to unlock all the doors manually with your hands after you unlock the passanger side. Any ideas on how to reset/fix this so it will work.

Another problem I want to mention is that when I push the window down for the passanger side, it only goes half way down but all other windows work fine. How can I fix this problem too. There is a major electric problem with the car because alot of lights are not working (interior). How would I go about resetting everything to normal settings? Would this fix my problems? Also, where are some good place to buy new/used parts for this car?

Thanks again in advance.

by the way, the car runs great, just this electrical problem and a few body parts need to be replaced and it will be like new again:)

Sounds like it's a . . . . .
 

broken "push rod" that manually unlocks the door. It's a 10" inch formed rod that pushes the door latch button up (or down) driven from the solenoid to unlock the door.

Same thing happened to me last year: must remove the door panel and the plastic covering to gain access to the part. If I remember correctly, the part cost $1.89 or so. It broke due to 'metal' fatigue.

But the repair is tricky since the part is only partially visible but you can do it.

are there any pictures you can show to guide me?

Sorry, but I didn't take. . . .,
 

any pics. But should have! :(
