stop light switch on '99 ml430

I need to replace my stoplight switch and can't find the location on the car, under the hood nor under the steering wheel. Anyone know exactly where it is located?

I took the car to have it analyzed and it came back saying that the stoplight switch needs to be replaced and that the MAS needs to be replaced. The dealer wanted $970.00US. I paid for the analysis, $98.00US.

I then bought a stoplight switch and MAS from internet and replaced the MAS. The check engine light went out. Can't find location for the stop light switch. The ETS/BAS light is still on. PLease help.

Thanks in advance.

Remove the left lower dash panel. Follow the brake pedal up to its pivot point. You will see the switch on a bracket. Twist left to remove. Put the new one in and twist right. FYI: pull the plunger out on the new switch before you install it AND use your other hand to HOLD the brake pedal down as you install the new one. When you release the pedal, it will come up and push in the plunger and you will hear it click as it self-adjusts.

Hey Karl,

Did what you said. Looks like they gave me the wrong switch, part #001-545-31-09. Plug does not match plus plunger seams to be 1/2" too long. Woes me... Do you know the correct part number? Thanks in advance again. Bryan

I am home now, so I can't help you on the part #. But, the plunger is adjustable. Push it in hard and it should go click click click and get shorter. That is how you adjust it. Remember, I said pull it out and hold the brake pedal down with your other hand when you install it. After you lock it in place, release the pedal and pull it up til it stops moving. The plunger will self-adjust. Are you sure it is the wrong one? It should have two plug connecters.

Yeah, I'm positive it is the wrong one, the plug is much bigger than the one I took out. The plunger is longer by 1/2". Thanks again. Bryan

Did you read the previous posts?

the plunger length isn't really an issue, it's designed to be shortened by the compression of the pedal...

If you already understood this and REALLY have the wrong part, my apologies...

Yeah, I did read and understand about the plunger. The plug doesn't. Totally different.

Thanks again, Bryan
