As you might guess one fuse box is located in the engine compartment and there is a second one is located in the trunk I believe near the battery. The car designation is W140.

there should be a disconnect either in the harness or at the motor that needs removed .. then it comes out.

Check the rear main seal, if its coming out between engine and transmission it is time to replace. Usually this seal wont stop leaking even with seal conditioner. Depending on engine and chassis either the trans or motor will have to come out in order to replace the seal. If the seal is external than remove the trans, if a 1 piece internal than engine has to come out. Any way you look at it is a time consuming and big job.

I hope you have a lot of spare cash to fix all of these problems as they are going to get expensive. The power steering rack has leaking seals and will need reconditioning or replacing with a new item. Run fault codes to determine which sensor is failing for the idling problem in the fault codes check for a TCM problem as it will affect the gear changing . The power windows may be a micro switch in the regulator assembly that can be fixed but it may require a new unit Console trim bits are expensive if you can get them but it nay be possible to get spares from a wrecker that specializes in you car.. Knocking noise will be either worn shocky mount rubbers or rear suspension mounts failed. The ride leveling system may be actuators or it may be failed units that again may be available from the wreckers. From the list of complaints I would suggest that the vehicle has not been properly maintained and even though the mileage is relatively low I would get estimates before I started restoration as I stated it will get expensive.

Disconnect the battery and leave for 10 minutes ... then re-connect and it will fix itself ..

Check the fuse or wiring problem

Have the oil pressure checked at a garage to be sure A manual gauge is more accurate than a dash gauge, in ten minutes you will know the true oil pressure. Check with the dealer for the pressure specifications for your car. If it really is low at idle, your money will be well spent on a new oil pump. You might try an engine flush to clear any blockages in the internal oil passages. Often, an oil change with clean oil will help.

I have to ask this question. Have you changed the battery? if the battery is good have you tried any other remotes. If one remote works and the other does not. The remote is probably bad. If all remotes do not work then the cars ecu for the door control could be bad or as simple as a fuse.

When the roof is closing and it stops does it make a juddering noise or is it quiet. First of all open the roof fully and check that the guide rails on either side are free of dirt, use a paint brush and WD40 and use plenty of cloths to prevent dirt splashing every where. I have a '96 E-class but I think the roof mechanism is very similar. If the roof make a juddering noise this is not so good. The motor is located above the left rear wheel in the boot. The mechanism consists of a toothed cable driven by the motor through a pipe guide to the rear of the roof panel. You will have to disassemble this motor and gain access to its drive gear in order to clean it of metal shavings/debris and to re-grease it. It is a very frustrating job and one that may wish to leave to the Mercedes experts because even having rebuilt the motor there is a real knack to adjusting it. If the roof is just coming to a stop and not making any noise then you in luck. Locate the motor and the large central nut on top is the clutch adjuster. Tighten it by 1/6th of turn and try to close the roof again. Keep adjusting the clutch tighter until the roof closes. If you hear juddering noises, immediately slacken the nut off and the above notes will apply.

this is a 12 hour job for a trained tech. you may want to rethink this one. but anyway the book that i work out of says the dash and windshield must be removed... good luck.

Have you checked your fuse? It should be marked in one of your fuse boxes. If the fuse is ok, you could have a bad wire or a loose connection.

some cars your light switch has to be in a certain position for washers to work on head lights
