HYDRAULIC PUMP/MOTOR ASSEMBLY
Any diagnosis of the power top system should begin with the use of a scan tool and the proper Diagnostic Procedures Information. The scan tool can provide confirmation that the Controller Area Network (CAN) data bus is functional, that all of the electronic modules are sending and receiving the proper messages on the CAN data bus, and that the power top motor is being sent the proper hard wired output by the driver window regulator module.
The convertible top system is equipped with a hydraulic bypass screw that is used to relieve pressure from the hydraulic system in the event that the top must be manually raised or lowered (such as a low battery or a convertible top operating concern). Always verify that the bypass screw is tight in the pump housing prior to replacing a hydraulic pump/motor assembly (Refer to 23 - Body/Convertible Top - Standard Procedure).
If the power top is completely inoperative and the hydraulic pump/motor assembly is suspect, perform the following:
(Refer to 23 - Body/Seats/SEAT BACK - Removal)
.(Refer to 23 - Body/Convertible Top/ASSEMBLY, Hydraulic - Removal)
. If not OK, use a scan tool and the proper Diagnostic Procedures Information to complete diagnosis of the power top system.
On convertible vehicles, the convertible top switch is hard wired to both window regulator modules by the Power Top Switch Mux circuit. When a top operation input is received by the driver window module, it will ground the respective relay control circuit which in turn will operate the motor. If the convertible top switch is pressed and held to the down position second detent, it will command both modules to drop all windows to the fully down position. The windows cannot be raised when the convertible top switch is in the top down position. When the switch is held in the top up position and all four windows are fully up, the modules will lower the respective front window 40 mm (1.6 in), lower the respective rear window approximately 55 mm (2 in) and the driver window module will ground the top up relay control circuit. Once the top is back up the windows will not raise automatically.
Your missing that you don't have a clue on how the electronic's on your vehicle work . Your best bet , take it to a qualified repair shop . Your trying to fix something you have no clue on how it works , going at it blind .
