I recently replaced my latching motors with REBUILDs and the top (After ~ 1 month) intermittently stops in ~ 5-6 positions when opening and closing the top.

Usually about the same location each time.

Anyone have issue(s) similar to this one with a solution?

Cold Solder joints on the controller?

Thank you for ant feed back,

Hi and greetings from Finland. I strongly suggest that you replace your controller box asap. My low-mile ´92 Cab with manually operating top had some issues last summer when unlocking / locking the top. The system became completely dead without any warning. I removed the controller box (real pita due to its location behind the gauge cluster) and checked it out - several bad solder joints found. I re-soldered all bad joints and voilá - works again. I´m pretty sure that a bad controller is one major reason for some top mechanism malfunctions causing main top bows breaking etc.

Mine is in manual mode now (as many 964 Cab owners has) but I have some thoughts to restore the electrics some day. I will surely renew the controller as I have seen what is inside an old one.

If it stops about the same location each time, I would look at the wiring harness where it flexes to accommodate the hood movement rather than at the controller/module which is fixed. Logic is: relays etc don't know what the hood position is unless at end of travel.

mine started doing the same thing. My top is down probably 10 months or more of the year so havent bothered to chase it down. Be interested to hear what you find.

Faulty solderings on the controller PCB is a common issue. The output connector pins will break loose. It's an easy fix for a guy with some experience with a soldering iron.

That was exactly the case on my controller.
