Convertible top will not move

[BoomerRoadie]

Hello,

I searched around and have some ideas, but I could use some more detailed help.

The convertible top will not retract (terrible time of year for this problem in Arizona!!). Anyway, when I set the parking break, pop the upper latch, the windows start coming down. So that part of the system seems to be working.

Then when I press the button to engage the motor, the top does not move.

I'm thinking:
1. bad motor
2. bad switch
3. possible a blown fuse
4. Parking break relay problem (but considering the windows come down...)

Thoughts on what I should dig into? And can you help me understand how to dig into whatever you are going to tell me to do.

Thanks!!
