Does anybody know where I an get the internal wiring of the Convertible top control module? Except for the fact that the windows do not go down when applying the top down switch ( I did wait several seconds for the time delay to kick in-nothing)the top down circuit seems to work. When I say work, I mean I can hear the motor even though there is no fluid as it looks like it had a leak and was never refilled . I bought it that way. I don't want to refill it because I know it will leak out before I fix the pump leak. Somebody here said the top does not have to actually move by motor and pump action for the quarters to go down. With that said, my quarters do not go down when selecting the top down switch.
Looking at the wiring diagram, It appears that a ground is applied from within the module to each respective window position relay. So when selecting "down", a ground is applied to the down side of the Top motor relay coil closing the power contact to the motor for down motion. At the same time for the windows where a ground from the module energizes the down window relay pulling the power leg for the down window motors of each window. If all the conditions to work the Top down motor are there (park brake, Tranny in Park, 0 mph, etc), because I can hear the motor even though no fluid, I would think the module would also give grounds for the window too. This is not happening ...to both windows. I am not convinced that both window motors are bad. Has this happened to anybody else? I may have to test each window motor.





Thanks

 

Just to clarify, there's no time delay on the down circuit for the windows. The time delay only appies on the Up cycle. It's possible both window motors failed but imo it's more likely that both down relays are suspect. Try swapping the up and down relays to verify.

good luck,
