Sounds like the front latches are either worn out, OR there is still air in the lines.
Usually it's the rear latches that are bastages.
In normal operation, the control unit has no "idea" if the window switches are open or closed. It just needs the signal. If the switch is bad it won't set a fault code. It just knows the signal is not there yet. I think it closes with the windows down. I had an operating schematic somewhere here. Might be a bit of digging.

Gilly,
I respectfully disagree with you in that the window limit down switches do not play a role in preventing the top from proper operation in the 90-93 cars. I found this document I'm going to attach, and it clearly states that the cause of the top stopping at 90 degrees is the window down limit switches. - Why would the car drop the windows to raise the top if it didn't care about the window position anyway...
Take a quick read here. I have all the wiring diagrams as well.
