I have looked through many posts to see if someone has had my problem. I can't find an answer. The car was working perfectly. I stopped at a deli to pick up a sandwich. Came back to the car and opened with the remote.(previous post, drivers door keyless doesn't work) I got in as usual.
Stepped on the brake and pushed the button. Nothing! OK so lets try the key in the ignition switch, I thought I heard a single click but still nothing. The battery is a genuine MB battery less then 2 years old so I didn't really suspect that but I didn't know what else to try while I was sitting in a parking lot. I called for a jump.
The jump also did nothing to solve my problem. Not even a click. Now it's getting dark so I have to have it towed home. Everything else works, headlights, radio, leveling and I can hear the fuel pump charging. There is no dimming of lights when the key is turned. I checked all the fuses under the hood and they are all good.

Still nothing. There are no codes on the car or a scanner. I spoke to MB this AM and they pushed me away from the brake switch and starter relay so now I have no clue. This is the 4th of July weekend so I have places to go but no way to get there. Any ideas?
