Front Height Will Not Go Up &/Or Down (Other Functions Operate Normally)

1) At inoperative seat, use test light to backprobe between seat adjuster switch connector C2 terminal "E" (Yellow/Blue wire) and battery voltage. If test light glows, go to next step. If test light does not glow, replace seat adjuster switch.

2) Backprobe between seat adjuster switch connector C2 terminal "F" (Red/Blue wire) and battery voltage. If test light glows, go to next step. If test light does not glow, replace seat adjuster switch.

3) Backprobe between seat adjuster switch connector C2 terminal "E" (Yellow/Blue wire) and ground. Move front height switch to up position. If test light glows, go to next step. If test light does not glow, replace seat adjuster switch.

4) Backprobe between seat adjuster switch connector C2 terminal "F" (Red/Blue wire) and ground. Move front height switch to down position. If test light glows, go to next step. If test light does not glow, replace seat adjuster switch.

5) Check for open in Yellow/Blue or Red/Blue wire between seat adjuster switch and front height motor. If circuits are okay, replace front height motor.
