2002 C230K Pano roof problem
 

I had the pano roof cleaned and lubed at my local dealer. When I attempted to open it, the shade opened fine but the roof did not open. It finally opened after 6-7 attempts but only 2-3" at a time. I closed the roof but then the shade would not close. I opened the roof half-way then tried to close it. It closed to within 3" of totally closed then a loud grinding noise came from the switch console and it stopped. I tried to manually close the roof, but still got the grinding noise.
The cleaning/lubing was preventative. Could that have caused the pano roof problems (or coincidence)? I don't know how deeply into the guts of the roof they go. The roof worked fine prior. Thanks.
