Hi

The door switch in one of your doors is faulty... The switch that triggers courtesy lights when door is open then disables light when door closes.Also check did you turn it on with the interior dimmer control on your dash, left side of the steering wheel?

You may need to replace the latch mechanism in the door. But more than likely it is just stuck...if i am not mistaken; it is a magnet system so it just got jammed. All you have to do is spray the **** out of the door hinges and door looks with wd40 or some other spray. Actually the problem is that there is a sticky switch in the door latch mechanism. This switch is telling the computer that a door is open, even when it is not. Keep in mind that it may not be the driver's side door that is at fault, so you might want to do all 2 or 4 doors, depending on your model. At each door you will see the latch mechanism. Just above these latches inside each door is the switches. To unstick these switches you will need 2 types of spray lubricant. Use WD-40 (or equivalent) and a can of silicon spray lubricant. With the plastic tube attached on the WD40 you will spray inside the latch and in between the latch to get the spray to lube the switch. Flooding is preferred. Go to each door and do this. Open and close each door multiple times until the switch is free and the indicator lamp goes off.

loose aux belt ?

Try the fuse first. If you have done this than the problem could be in the actuator on the trunk latch. Poss loose/bad wire or faulty unit? I hope this helps!

Hi:

You could try connecting a battery charger to the generator's output terminal since the battery is connected directly to it. Be extra careful not to short that connection to ground (chassis of the vehicle)! After the battery has been charged enough, use your remote or the button for unlocking the trunk. You may also look up for a large positive terminal in the engine compartment and connect the charger there. Good lick and post the results here.

How to open my hood on the outside of my S320 2000

2003 Mercedes E320 fuse box location is in the trunk and under the hood an inside driver side Dash

You will need to trace the wire back towards the supply of power, could be a loose connection for example

It is called Parasitic Draw, one item is being left on and is draining power. Attach an ammeter to the battery. Remove fuses one at a time, keeping an eye on the ammeter. When you pull one fuse, you will see the reading drop a lot. That circuit is the one causing the problem. When you know the fuse, you can check all the things it covers. There will always be some draw because items like the clock and a number of modules are constantly powered. In general terms, you can't find work-arounds for problems like this, you have to fix them. Or, you can take the vehicle to a good auto-electrician.

The most common 3 reason why your Mercedes is running rough are a vacuum leak, an issue with the spark plugs, or a problem with the ignition coil. Clean out the throttle body and make sure there is no ware at the butterfly pivot shaft .
