Don't know if this is relevant or not but I had a similar problem with my 1992.
Replaced the 2 top locking cylinders and then proceeded to cycle the top and rollbar a few times to purge the air.
After 3 times it stopped in the locked position with the rollbar up.
The soft top redlight just blinked when I tried to lower it and the rollbar switch did nothing , although when you turn the key on, the red lights inside the switch flashed momentarily which told me it must have power.

Tried the "holding the switches for a while" trick but to no avail.

Checked all the fuses and gave them a little tweak to make sure of good contact

Disconnected the battery for about 1 hr but still no action.

Tracked down the sequence for clearing the 16 pin diagnostic code ( Thanks Bob Terry !! ) and found it had quite a few codes.
Spent the time to clear them all , which can take a while when it blinks 20-24 times and guess what?

Once they were all cleared, everything worked again..

Thanks to the forum as I had visions of an expensive trip to the dealer..

Cheers
