Drivers power seat issue
Before I start to dig into this, would like some insight. The 6-way drivers power seat does not go up or down, it goes foward and back and tilts , but no up or down. Switch, gears, motor, tracks?

Codes
- Any SCM codes show in the DIC ?? From the manual : Power Seats Description A seat relay center consists of 6 single pole double throw relays, and are normally closed to ground. Battery voltage to the relay coils, or the control circuits is supplied through circuits 1740 (drivers seat), and 1140 (passenger seat). Battery voltage to the relay switches, or the adjuster motor feed circuits is supplied through circuits 1840 (drivers seat), and 1440 (passenger seat). The relays are controlled by the seat adjuster switch assemblies consisting of one switch for each relay. Each switch is on the ground side of the relay coil, and when a switch is held in the closed position its relay is energized. The seat lower motor assembly consists of three adjuster motors, horizontal, front vertical, and rear vertical. An individual adjuster motor's operation is controlled by a pair of relays, the energized relay supplying battery voltage, and the denergized relay providing a ground. The direction of the adjuster motor's rotation is determined by which relays are energized and denergized.
