04 350z top won't go down
 

Originally my top was up and close, but I have to put a new passenger rear Quarter panel in. So my top had to be opened and the hatch has to be up while I drill the tig welds. I tried the normal operations with the window down brake pressed and passenger seat tilted but all i hear is a clicking in the door panels(I believe). Well, I ended up going thru my trunk pulling the two release tabs and I used a .05 Allen key to raise the latch. Afterwards, I opened my top and pushed it down it the hatch area, now the problem I am having is that 3/4 of the top went into the hatch, and the rest is sticking out. I understand the door and 5th bow motor are all the same thing. Should I try replacing the 5th bow motor or the two motors in the trunk, how can one tell which is the bad link
