anyone out there ever experienced an electric sunroof panel that would open but not retract fully ??? also...when closed from the raised position it doesn't stop operating at closed it continues operating until it again retracts to about 2/3 open when it will stop...it shakes-vibrates slightly right before it stops retracting...i've tried retracting the sunroof panel fully via manually turning the sunroof panel motor until the sunroof panel stops at fully retracted...however then when using the sunroof panel switch to close (it) stops at 2/3 open & ten i can close it again via manually turning the sunroof panel motor & then operation revertes to the original complaint...i'll monitor this message for replys over the next couple days...thanks
