its a relay under the hood

I would check www.car-part.com. You enter the year, make and model, part, and your zip code and they will direct you to salvage yards in your area that may have one available.

There are several possibilities and you should have a wiring diagram if the problem is not moisture. Some manufacturers put the relays on the firewall or the area beneath the A/C pipes. There are several parts on the A/C that sweat while working.

The water gets into the relays and shorts them out. Because the relays can link to other wiring and the mounting holes are in the same place, the mechanic reinstalls the new part in the same bad place. You should look under the hood for the relays and note water and rust in the area.

If you are not the original owner, someone may have used the same relay twice and overloaded the relay by bypassing another bad relay. This is why you would benefit from a color coded wiring chart.

It is also possible that the Voltage Regulator is bad and letting too much juice in the entire car system. The same relay just happens to be overloaded and as the weakest link, it continually fails. Autozone and Oreillys can scope your car for free and let you know what the Voltage Regulator is doing.

On the inside trim, you can remove screws (these screws may be covered by filler pieces or may be visible, or they may require you pry a plastic piece off that covers the screws) that are by the door handle, arm rest, under door and side of door and then gently pull back on the panel as there will also be retaining clips attached and you don't want to break them. You'll need to lift the door panel upwards in order to get it off the window ledge. Then you'll need to manipulate the panel and disconnect the door handle linkage from the door handle and disconnect the wiring for your controls.

Not knowing what year your car is I might guess it could be a couple of things .. the cat could be pluggin off or the fuel filter might be getting plugged also .. just a couple of things to look for .. thanks jerry and holler if you need more ..

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.

Pull the fuse that does the audio system, count to 10, put it back in and try again

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 .
