You might of blown a fuse somewhere. This happened to me with an 89 Z-24
convertible on  trip out east. I lowered the top and suitcases had
shifted in the trunk and stopped the framework from folding on one side.
The one time I didn't watch the top go down and something happens.

The Top wouldn't raise. I switched out the circuit breaker with the
power window breaker and it still wouldn't go up. I had to drive home
from Erie, PA. (600 miles) to Chicago with the top down at 98 degrees.
At night, when it got dark, I noticed I had no courtesy lights when the
door opened. I thought that was strange as they had worked the previous
night.

I checked the fuse for the courtesy lights and it was blown. After I
replaced it the top went up and down fine. Nowhere in the owners manual
or fuse chart did it say anything about the top circuit being run
through the courtesy light circuit.

During the course of the day I tried jumping the top motor, the switch
anything to get the top up but nothing worked. I even swapped out the
relay in the trunk with an old relay I had kept after buying the new
one.

Good Luck.
