In your 1999 archives, there is reference to a sunroof problem as follows:

"when I trigger the sunroof switch on my '99 CLK that the sunroof would only open about 5" at a time, so I would have to activate the switch numerous times before it would fully open"

you replied as follows:

"Mercedes knows about the problem. It's the overhead control unit(dome lamp). Try to resyncronizing the system by going to the pop-up position & holding up on the switch for 4-6sec, you should hear a "click" from the unit when it completes the task. The modified unit should be avail. & shouldn't have this problem, see your dealer!"

My dealer wants to order the correct part, but cannot tell from this description whether I need a motor, relay, or both. Can you be more specific?

Thanks!
