Ok. I own a 2004 c230 k sedan. The car hasn't given me any problems up until two days ago. Got up around 10am drove to the cleaners, parked and turned it off. Drove to the barbershop, parked and turned it off. Then drove to the bank, and to the car wash. This time I parked the car turned it off and washed the car. ( I didn't wash the engine bay) just to make that clear. I finished washing it and was going to move it into a different stall to dry it. Inserted the key, all interior lights came on, but I turned it fully to turn the car on... Nothing, just a click. No starter engaging. No lights dimming. Nothing. Called someone to pick me up, hooked up a memory saver to the car, was able to take the battery to autozone. They said it was a good battery. 12.4 volts. I cleaned the terminals, put the battery back in. Still nothing. Checked the fuses. I'm stumped. Going to take it to a mechanic on Monday. But maybe someone here might know what happened.
