2006 Nissan 350z convertible top sticks, will not fully open

Replace the bad motor?

You need to have the codes scanned for the top. Their are many sensors and switches to these. Not to mention the mechanical parts. I suggest you don't use it till you have it diagnosed.

Lubricate every single part that moves in the top frame all the hinge points, use a light oil like 3 in1. Wipe off the excess do not get it on the interior trim like seats and door panels. Move the top up an down a few times to work the oil in and then try putting it all the way down. Good luck

ok make sure there is nothing stopping it like a arm that is part of the frame sometime the rivet come lose or rot off,or the motor may be on its way out

MY 350Z ROADSTER HAD THE SAME PROBLEM CLOSED TOP ON SLANT CAUSING PROBLEMS W LATCH MECHANISM. IN THE THE RIGHTMOST LATCH IS A SWITCH WHICH NEEDS TO BE FULLY DEPRESSED BY THE END OF THE HOOK IF ITS NOT EVEN THOUGH EVERYTHING IS LOCKED LIGHT WILL STAY ON. IN MY CASE THE RUBBER COATING OVER HOOK HAD COME OFF. SOLUTION WAS TO INSTALL RUBBER SLEAVE OVER HOOK AND THE SWITCH WAS DEPRESSED AND LIGHT WOULD GO OFF.SWITCH OPERATES LIKE DOOR AJAR SWITCH. ALSO MY TOP HEAD TO BE SLIGHTLY REALIGNED TO CENTER LATCHES IN SLOT. ON THE INSIDE OF THE TOP WITH THE TOP HALF RAISED YOU CAN SEE TWO STOP ADJUSTMENTS ONE ON THE LEFT AND ONE ON THE RIGHT. THEY HAVE A ROUND RUBBER HEAD ABOUT AN INCH WIDE WITH AN ALLEN SCREW IN MIDDLE TURNING SCREW DETERMINES HOW FAR FORWARD O BACK THE TOP STOPS. AFTER ADJUSTING THE SCREW IS LOCKED INTO PLACE BY TIGHTENING NUT A BASE. MAKE SMALL ADJUSTMENTS TILL YOU GET THE HOOKS CENTERED. HOPES THIS HELPS SOMEONE.

Did you ever find a solution?

The engine has to be running the parking brake set if stick shift or in park if auto. and your foot hasto be on brake.

The key switch may be worn enough that it is not turning all the accessories off when you pull it out.

make sure your car is in park and that you have your foot on the break....if you release your foot it will stop. So keep your foot on until it is fully open or fully closed and the passenger seat has returned to where you had it set prior to opening or closing

check for voltage to the top motor and the relater fuzes and relay.
