hey all..my top stops when trying to go down..and i hear a grinding/knocking top noice when the boot tries to move...same when it goes up...i can help it along and all is well. now it wont even let me help it. i searched high and low in this site and saw some similar probelms..i even tried looking under the trunk rug for a motor that may need tension?? i can tell teh knocking sound is coming from the passenger side, in the trunk area..any help would be greatly loved...thanks!!
