Retractable roof inoperable. Three sensors in back okay, ohms good, fuses okay. Disconnected battery no codes. Don't know about body codes indexed windows. Any solutions?

Hello,

Can you hear the pump motor working when you are trying to activate the top? The pump motors go out on these which stops the top from working. To be sure here is a guide to help you check for power at the pump with the wiring diagrams so you can see how the system works with the top exploded diagrams so telling you how the mechanical side works:

Check out the diagrams (below). Please let us know what you find. We are interested to see what it is.
