After putting back in the window switches I found that only the driver's window works. I checked the fuses and they all looked good, I replaced all of them not long ago. I took the switches apart and cleaned them a while back so i know that they're clean. I wonder if there is something wrong with the lock or if I might have put back something wrong?

I also put in a new stock antenna and found that the connector in my car had been taken apart by the previous owner when he put in an aftermarket antenna. Luckily the antenna I bought had the male and female connectors; unfortunately the cable colors don't match up the ones in my car. I found a write up online, I hope it works:

Mercedes connector in car

•Pin 1: Combined Red and Red/Yellow/White = power
•Pin 2: Blue w/ Gray stripe = trigger
•Pin 3: Brown = Ground
•Pin 4: Empty
•Pin 5: Black = intermediate up (I think, or maybe down, but it may not matter since I think the antenna works by comparing voltages across pins 5 and 6 at the antenna plug. I plugged the black wires from the antenna into pins 5 and 6 and it worked as advertised. Maybe I got lucky, or it doesn’t matter)
•Pin 6: Blue = intermediate down (or up?)

Wires on antenna (no connector, just loose pins, I think I’m missing some sort of pig-tail adapter)

•â€śPin 1”: lightish Blue = power
•â€śPin 2”: Green w/yellow stripe = trigger
•â€śPin 3”: Brown = ground
•â€śPin 5”: Black = up, or maybe down
•â€śPin 6”: Black = down, or maybe up
