Do you hear any sounds when you hit the remote lock button?
Does the other side work? If so the remote control is fine you will have a problem with the auto door lock solenoid or the wiring harness inside the door panel. If no sounds occur you may have a broken wire leading to the door lock solenoid or a defective power lock switch which needs to be tested with a 12 volt test light on the output side of the switch.
Power door lock switches and solenoids may be hard to locvate in a domestic Auto Parts store such as Auto Zone etc. you may have to call around to find a Foreign Auto parts Store in or near your area and consult with them as to what parts they have for your vehicle, Mercedes may be the only stocking parts house for this type of repair.
If you are a DIYer and are not completely familiar with testing continiuty or Direct Current power in a circuit it is not a perfect job for you, If you can, find a reasonable repair shop and ask them for an estimate before they repair the problem so you have an idea what you are up against dollar and cents wise before hand. Good Luck.

Need to locate fuel filter on 1989 mercedes benz 300e


The fuel filter is located on the right rear underside of the car, just ahead of the rear axel area. You need to remove the cover to find it. It is the large canister next to the electric fuel pump.
