I have a 1999 C230 kompressor. I did not start the car for about one week. When I did try and start it the battery was dead. Afterrecharging the battery it was determined that the battery was dead a new one was purchased. After replaceing the battery the windows, windshied wipers, and blinkers worked fine. One day later the car was starting fine, but the all of the items I spoke of before stopped working including the remote that locks and unlocks the doors. I had the battery and alternator checked and they were ok. Someone please help. Thanks

 

Find a local independant shop and have them look it over. It might be a fuse or something may need to be reset.
