Well I took my car in to a mechanic. He said that he thought it was the relay because he can still hear a click when he presses the button. He will replace the relay and I have my fingers crossed that it'll work. A new relay is around $600, I opted for a used one at $100.
I trust this mechanic because he only works on mercedes. He's a german guy who's worked on mercedes for MANY years.
He told me that he first suspected the switch because that is usually the part that goes bad. I told him I eliminated that possibilty by testing the switch on the passenger side.
I'm having other minor work done on the car. When I get it back I'll keep everyone posted on how it went.
