Convertible Top Switch Circuit Part 1:

Convertible Top Switch Circuit Part 2:

CIRCUIT OPERATION
When the convertible top switch is operated, signal is sent to the convertible top control module. The convertible top control module sends convertible top switch "ON" signal to the power window main switch to lower the door windows automatically. The power window main switch lowers the door windows and simultaneously sends the "AUTO DOWN" signal to the convertible top control module. When the "AUTO DOWN" signal is received, the convertible top control module drives the quarter window regulator motor to lower the quarter windows and simultaneously drives the topstack drive motor assembly to operate the electric convertible top.

TECHNICAL DESCRIPTION (COMMENT)
The cause may be a malfunction of the topstack control module circuit.
