have no power leading to the convertible switch. Are there any circuit breakers or fuses that I should look at? Also, my power windows have no power to them unless I jump power from the battery directly to the bank of switches in case the electric windows all work under that condition so they have no power as well. Any help would be appreciated.

Exactly where on the firewall will it be? In the engine bay or under the dashboard? The maintenance manual refers to a circuit off the starter.

There are 2. One attached to starter solenoid and one near the center of firewall
 
Most likely the problem is failed contacts in the power window safety relay.
It is located on the center firewall, labeled C1AF-14677-A.
Since reports indicate that the reproduction relays do not last,
a better solution may to replace it using a Bosch-style SPST 4-pin 40A relay.

Thread '1964 window relay replacement with modern relay.'

Has anyone replaced factory power window safety relay on firewall with a modern relay? If so can you share anys pictures, part numbers or wiring connections? A/C is down and window relay is very intermittant after not even a years time. Tired of rapping on relay to get windows to go down. Hot in Missouri.
 
Thank you all for the ideas. It turned out to be the power lead to the main window switches that vibrated off. Just to note that someone prior to me use that main window power lead to operate the convertible top switch. I don’t think it should be done that way, but it was a quick fix from the previously owner. Thanks Dave
