Top has quit working.

[Retroman1969]

Day before yesterday I put the top down during my drive, parked it with the top down overnight, and next morning when I went to raise it to go to work, it was dead. No noise or action at all. I can hear and feel a relay clicking in the dash switch when pushing it up and down, but otherwise nothing.

First thought is one of the switches on the shifter or handbrake. Played with those all day yesterday but was never able to activate the top.

How many likely culprits are there so that I know what to check?
(I know there are micro switches in the top latch, windshield frame, parking brake, shifter, and of course the dash switch. Relays, although I don't know how many or where, and God forbid, the motor and transmission assemblies.)
The top has done this twice before, but worked fine again after a couple of tries. So it's an intermittent problem.
Thank you for any input!
