hello again...just got this CLK as a gift. Need help with the top....put it up and down a few times, no issues...the last time I put the top up..as it neared the end of the “cycle” the motor securing the ”hook” center latch..as it finished it slowed considerably almost to a grinding...it latched and locked...I’ve left it up..accidentally hit roll bar button while detailing....again they went up no issues...but going down, same thing...slowing almost to a grind ....I’ve checked the trunk for fluid..nothing...does the same motor engage both locking mechs?. Any other clk owners have this happen? I have no clue even where to start on this....please advise.
