SL 500 Convertible roof issue
 

My 2006 SL 500 top was leaking oil from a cylinder so the top was slow to engage up or down. I had the cylinder replaced and the top engaged but when it neared the trunk it dropped in vs a slow descent like before. Opened and closed the truck 3 times but on the 4th try nothing but the motor/pump...top not opening and windows not going up or down. Tried a number of times, now no motor/pump sound at all. Can it be the motor or a fuse. Thanks for any help!
