Circuit/System Description

WARNING: This page is about a different car, the 2019 Buick Cascada, 2018 Buick Cascada, and 2017 Buick Cascada. However, it is still accessible from the selected car via links, so may be relevant.

When the seat horizontal forward switch is pressed, battery voltage is applied through the seat horizontal motor forward control circuit, an inline 470 Ω resistor, and the signal circuit to the folding top control module. In response to this signal, the folding top control module applies battery voltage through the horizontal motor forward control circuit and ground through the horizontal motor rearward control circuit to the easy entry seat motor. The motor runs to move the entire seat forward until the switch is released. When the seat horizontal rearward switch is pressed, battery voltage is applied through the seat horizontal motor rearward control circuit, a 220 Ω resistor, and the signal circuit to the folding top control module. The folding top control module reverses the polarity applying voltage and ground to the opposite circuits to move the entire seat rearward.
