I believe it is located in the front left SAM(N10/1) under the hood driver-side. It should be green. Location M. You may have to lift it to see the letter underneath to verify the correct location. If you have someone that can help you, have them turn the key and put your finger on the relay. This will verify that that you are getting the start authorization signal.

I thought they where either on the side of the core support(follow the wire harness and it should go to the relay). If not remove the fuse box lid and then take out the screws retaining the lid housing and you will find a series of relays. There will be one for high speed (engine uses this when temp. is to high) the other is a low speed relay(this is the climate control aux. fan relay) They may have fuses on top of them I know the older models did. I hope I have been helpful.

Where is the fuse is that for the starter and my 99 Mercedes Benz E 320

Daryl, fuse #59 in the driver's side fuse box under the hood powers your starter relay. Attached is a pic of your starter relay, which could also be the reason your starter isn't engaging.

Also check the fuse for your starter relay and it's holder (polish off deposits)

I had a similar problem once with an Audi. I found that the relay in that case was in a plastic box about 5" x 7" under the hood. At first, I did not even realize it was able to be opened then a friend popped it open and there were several relays,( in my case the fuel pump relay) and switches inside.

You might look for a similar situation. Seems the Germans have a habit of hiding things in plain sight. Hope it helps.

09 mercedes c350 won't start able to turn ignition switch unable to shift no noise no nothing

I just went through this two days ago. You probably need a new ignition. What happens is these cars lose connection for some reason to the chip in the key and it can't be fixed with just programming. It has to be a whole new ignition. Mercedes are so much different then to any American car. Good luck and it costed around 950 to fix in Wa state.

08 c350 just will not start


If its auto trans, try starting in neutral.

Otherwise, sounds like the starter motor.

Test the live feed, to the starter motor, and solenoid, with a 12v test light.
If feed is getting there, a new starter is required.

Good Luck !
A FixYa rating would be nice please !
