Hello everyone,
i am having some trouble w/ convertible top. I can open and close it, but the last step where the latch is supposed to come up and lock the tonneau cover tight does not happen.
before I start spending money on switches and parts, I was wondering if anyone knows of a manual that can help me trouble shoot and determine what part is the problem.
would appreciate any feed back I can get.

 

PM me your e-mail address and I can send you the section for the convertible top. Here is the circuit description for latching the top.
Folding Top Control Switch
The folding top control switch is a rocker type switch that controls open and close functions of the power folding top. Battery positive voltage is supplied at all times to the switch from the REAR FOG/ALDL TOP SW fuse located in the body control module (BCM) fuse block. When the folding top switches are pressed they send a 12 volt signal through the switch signal circuit to the folding top control (FTC) module. The FTC module then commands the folding top to move in response to the switch signal.
Folding Top Control Module
The folding top control (FTC) module when commanded controls the opening and closing of the power folding top through input information from folding top position switches, top limit switches and class 2 messages from the door control modules and body control module. The FTC module is capable of determining the state of all moving components of the folding top system at any time during an open or close operation. Also through input information, the module can make corrections in the position of components when necessary while continuing in the direction indicated by the folding top control switch.
The FTC module can stop operation or reverse direction during any point of operation when you change the direction of the control switch. To avoid an inadvertent operation of the folding top system when the top is fully open or closed, a 0.75 second delay occurs after the activation of the control switch before the FTC module activates the pump motor and the valves. When the system is activated from a suspended state, the response time is less than 60 ms.
Folding Top Cover Latch Actuator
The power folding top system includes a folding top cover that is powered open and close by a hydraulic system that is controlled by the FTC module. A power unlatch motor is used to unlatch the folding top cover before the folding top control (FTC) module powers the top cover open. The folding top cover unlatching is requested by the FTC module via class 2 message, but is executed by the body control module (BCM). When requested, the BCM applies battery voltage through the folding top cover release relay control circuit to the tonneau release relay. The relay is energized and battery voltage is applied through the folding top cover release control circuit to the latch actuator. The actuator is energized and the latch releases the folding top cover.
Folding Top Cover Pull Down Actuator
The purpose of the folding top cover pull down actuator is to compress the folding top when its in the down position while the cover is being closed.
Battery positive voltage is supplied at all times to the folding top cover pull down actuator from the TONNEAU RELEASE Fuse located in the BCM fuse block. The pull down actuator is also provided with a control circuit, an ajar status circuit, and a ground circuit.
After the folding top cover latch actuator releases the cover, an internal switch in the actuator opens the control circuit to the pull down actuator commanding it to raise the striker. The pull down actuator will turn itself off once the striker is fully extended. Then with the striker in the extended position, the folding top cover pull down ajar signal circuit is pulled low signaling the BCM the ajar status of the pull down actuator. After the folding top is in the desired position, and the folding top cover is closed and latched, the internal switch in the latch actuator closes pulling the control circuit of the pull down actuator to ground, commanding it to retract the striker. The pull down actuator then reverses polarity of its motor to retract the striker in order to finish closing the cover.

This is just a very small sample of the manual. It includes all the troubleshooting, electrical schematics, fuse locations, limit switches, and the electrical connectors with the wiring marked as to what it is for.

 

Thank you 4SUMERZ for your help. My email is Edpezzi@icloud.com
thanks to all for the help. I followed suggestions and managed to do a power window initialize since I did have the battery disconnected. I then, proceeded to take off the waterfall. Good instructions on how to remove it.
I then, followed the instructions on how to remove the tonneau pull down actuator and ordered the part from rockauto as was suggested. Fingers crossed this will get me up and running.
really, really, appreciate all the help. You guys are awesome.
