I can't figure out how to open the gas door on a 1995 Sl500 Mercedez. Any idea

You can open your gas door from your trunk,under the fuse door

Hi Your S class has two batteries. The smaller one is located in the engine bay, and the bigger one in the boot (trunk). No need to access any of them, simply open the door with key, insert key to start engine, you will notice that not all ignition lights will come on, but the engine WILL start, and the batteries will be recharged after a short while.

Common problem if your lucky it might be written in your owners manual. I have seen people write it on the housing of the radio itself.Good Luck!

Should be a button or lever either under the left side of your seat, or by your light knob. push button or pull lever, if door does not open then you have either a broken/stretched cable (if you have a pull lever type release) or most likely a frozen (as in not moving, not literally) gas door lock. Hope this helps!

Spin the barrel fuses as corrosion can stop them from working.

you should be able to pull down back seat to get in the truck,and once inside there should be a visible pull cord to open trunk.

Lower all windows,enter car shut all doors +boot.Raise and lower all a few times,Raise all should reset.

pop the trunk, same side as gas door pull the interior carpet down or back. Look for a wire with a loop on the end, pull it. "The door should open

hopefully will be a easy fix this one, first check the micro-switches for the roof assembly (in the boot) and check any ground wire connections

you could try resetting the system also as this may help

if its still the same after this post back and ill try and help again.

probably your sender unit. do you drive a wagon? if so go into boot area and lift up all your carpet. just behind the rear seat there are 3 or 4 bolts, you need to undo these. then lift out the sender unit and take it to someone who can test it for you.
