Convertible Top Issue (watch video)
ISSUE RESOLVED!!!! LIMIT SWITCH!
My problem is now fixed!...it was the limit switch at the bottom of the 5th bow left driver side. two switches there..both blue with metal brackets. one of the metal brackets on the switch was out of alignment.. realigned and top is working now!
Watch my youtube video please!
Ive gonna through 20 pages on the forums and no one seems to have this problem!
Ive come to a conclusion that the Auto closure wire in the Tonneua cover will not stay in the motor. Anyone have a similar problem? Any help would be appreciated! THANKS!
The top is very stubborn when trying to unlatch and open. I have to repeatedly press the open switch 10-20 times. This is NOT a 5th bow motor problem. Eventually the 5th bow raises to let the tonneua cover free. As the 5th bow is coming down it goes further then it should and gets stuck (watch videos of properly working tops). The only way to move the 5th bow again is to unplug a gray switch and then replug it after the 5th bow rises. Once replugged the tonneua cover closes and then the 5th bow closes. A few unsuccessful things I've tried. 5th bow motor rebuild via 350z Forums. Cleaned only did not need rebuild. All motors seem to be working fine. Ive tried the service bulletin "5th bow will not close" where the lock mechanism in the tonneau cover is lubricated and the auto closure wire is twisted back into the motor (or "jumped using 12V" if it doesn't twist). Swapped open/close switchs with another Z. I did change the oem vinyl top to a cloth top but I can't see the that being the problem since the top worked perfectly fine for 2 months. Any help would be greatly appreciated! THANKS!

There are some things where you just have to suck it up and take to the dealer.. It looks like your 5th bow is struggling and might be going bad.. (This is the windows motor) and the others already look shot. (Rest of the top) although I could be wrong.. good luck whatever you find. I am just sucking it up and taking mine to the dealer =\

It not the 5th bow motor (the one in the soft top itself). I just cleaned a 5th bow motor on my buddy's Z yesterday..didn't need a rebuild. Its running like new now. So I know what a sluggish 5th bow motor is and this is not it. You can clearly see the 5th bow going up and down without a problem once its free from the tonneua cover. Thanks for the reply and I'll hold off on the dealer for now. I know there are some knowledgeable people on this forum that can help.

Thanks for the reply! I too think its one or more limit switches...looks like a problem between operation 6 and 7 (and/or) operation 7 and 8. But when i noticed that the auto closure wire just wont stay inside the motor that's inside the storage led..that just threw me off. I think I just have one huge mess.

are you talking about the control box behind the seats under the lid? I can't find any switches that are blue. I replaced the brushes on the 5th bow motor and it worked great for two days and now I have the same problem your had in your video. The elastic straps seem to be in good shape.

Help
Was wondering if anyone had any ideas why my soft top on my 350z after l had a new soft top replaced after a small tear now will not go down all the way and latch it sit about a inch of the latch. If we pull the glass toward the front of the car as the roof isgoing down it will then close and latch. Have taken to a few places but nobody can tell me why it wont latch ??? Need some help or ideas.
thanks Deb

Debra Blake, Did you ever get this figured out? I have the same problem with my top. When I close it, it stops about 2" above the windshield. If I force it to closed the latch lets go as soon as I hit a bump.

Your limit switches are located below the driver side 8" struts. Look above the door striker, you'll see where everything is anchored. It's on the back of that, has a small silver blade.
