1999 E300 TurboDiesel Fuse Diagram - PeachParts Mercedes-Benz Forum

Hi guys,

My wife had a well meaning guy reverse polarity when trying to jump start her 1999 E300D resulting in quite a few fuses being blown.

The battery wasn't low and didn't require a jump start..... long story...… So, my charging system is working correctly and was not damaged.

I have found several blown fuses in the mani fuse panel, driver's side fender and am looking for the fuses that supervise the driver's side window and the CCU blower motor.

I find the fuse diagram a bit confusing as when the fuse description is shown for a particular circuit, there are often several numbers associated and some numbers have an asterisk next to them but there is no key that tells me what the asterisk implies. Nor do I understand why some fuses for example: "Fuse so and so 4,7,(11)*……. What does that sequence of numbers interpret into?

Thank you for any replies

There is a legend on the fuse card that explains the markings. Not near my W210 at the moment so I can't go look.

There are fuses in the following places:
- under rear seat by the battery - all circuits on this box are unswitched battery.
- Under the cover by the master cylinder - most interior devices here
- inside the sail panel by light switch - all exterior lights
- under the cover on right side of engine bay - all engine controls

The climate blower has no fuse in a fuse box, it takes a straight power feed and is internally protected in the regulator.

Drivers front window I think comes from the front fuse box, the window motor is controlled by the door control module behind the door card.

You may have a whole mess on your hands, lots of electronics in this car. Can you start and drive it?

Don't know if this will be any help to you:

Hey jay bob, thanks pimpernell

From what I can tell almost everything works with the exception of the 2 above mentioned though today I will check all functions.

The car starts, runs and drives just fine, when you put on the AC you can feel it get cold but the blower no longer comes on.

What regulator should I check that protects the blower motor and what is the process???

Hopefully, I'll find the fuse for both the drivers side front seat and its side powered mirror,

RThank you for the link as well

Climate blower regulator is in the motor assembly. This is accessed behind the panel under the passenger side dash.
