I had the same, gave up, and had to have my shop scan for body codes with a Tech 2, and that led me to broken wiring.
It's got a wire or switch not reading right.
The car takes the command to unlatch the top and raise, it unlatches then checks that the latches are open. If the switches aren't reporting open, it shuts the pump down, rather than operate the rams and break stuff.
Autozone scanners won't do it. You need a good shop that has a Tech 2 or will do GM body code scans.
With codes, you can use bulletins on this site to track down issue.
