I have a 99 Slk 230 and I have having problems with my alarm as well as the button that puts the top down. I have replaced my PSE pump in the truck and it works but when I plug in my alarm fuse, it goes off. No one can seem to find the problem. Also, my button for the top blinks and beeps at me, like the trunk is not closed, but it all works properly. When I try to put the top up the quarter windows wont go up either. I just put a new radio in, anyone think they may be connected. Alarm problem happened before the radio. Any info would be greatly appreciated.. had it to 2 shops and no one knows!
