While depressing the brake pedal, pull the plunger pin all the way out then release the brake pedal. Check a number of times to see if the brake lights are working properly. If not, you will need a new brake light switch.
ok I did the switch test, and it still does work so I 'm looking for the wright switch to get.
(While depressing the brake pedal, pull the plunger pin all the way out then release the brake pedal. Check a number of times to see if the brake lights are working properly.)
The switch thats in right now, the only numbers I could find on it are 06W36, the bottom where the wires connect and plunger are white.
Can I get any type of brake switch?
do you know if there has been a recall for this?
In my last post I forgot to include the fact that there is a recall for the brake light switch, but the reason why you didn't receive a recall notice is you never notified M/B that you were the new owner.
The notice probably went to the last known owner that M/B was aware of and he or she threw it away. You must call M/B Customer Assistance Center @1-800-FOR-MERCEDES ask them to send you a NOTICE OF PURCHASE OF USED CAR form. Then discuss having them send you a recall notice.
As for the brake light switch, I would purchase one a dealer and install it yourself. Then wait for the recall notice.

If the brake pedal assembly doesn't contact the switch and push in the plunger, it will never turn off the brake lights and the computer may think the brakes are activated and not allow cruise control or the BAS system to work properly, if at all. Without being able to examine the assembly first hand, I can only guess as to why the parts are not relating properly. My first two guesses would be that you were given the wrong switch or that it's mounted incorrectly. It must be mounted in such a way that the plunger is pushed in far enough to switch off the lights when the pedal is up.

Since you became a member in Oct. and this was your first post, there might be a possibility that the brake booster was replaced prior to your buying the truck.
If that was the case then the booster rod was not adjusted properly. Remove hairpin #25, and then remove connector #26. Push booster rod off of the brake pedal and pull brake pedal upward and see if it now makes contact with the brake light switch.
If it does then you will have to keep the pedal up and turn the rod counterclockwise until the the rod is properly aligned with the hole in the brake pedal.
My suv had cob webs hanging from it and I didn't have alot of free time so I brought it to the dealer and it turned out that I slambed on the brake pedal to hard and bent it.
Had the pedal replaced the brake light switch was fine, tuned it up, computer is ok, they found problems w/remote and rear passager door lock that need to be replaced, which will be another day and new post, other than that it works good.
I would like to thank everyone for the great help, I learned alot!
