Ford Left Power Seat Switch Wiring Schematic, Testing & Connector Pinouts

This document is a service reference page for the left (driver's side) power seat switch on a Ford vehicle, showing a wiring schematic, a component testing procedure, and connector terminal views. The schematic illustrates the internal switch contacts across all positions, with a legend defining each numbered position: 0 (Rest), 5 (Seat forward), 6 (Seat rearward), 7 (Front up), 8 (Front down), 9 (Rear up), 10 (Rear down), 11 (Seat up), and 12 (Seat down). Two connectors are referenced: C352 (used with Super Cab models) and C3016 (all others). The component testing table explains how to check the switch with a self-powered test light or ohmmeter, listing which terminal pairs to probe on each connector, which switch position to select (forward, rearward, up, down), and whether a good switch should show a closed or open circuit for each test, covering the forward/rearward circuit, front up/down circuit, rear up/down circuit, and up/down circuit. Terminal face-view illustrations for connectors C352 (Super Cab, figure F08112) and C3016 (all others, figure F08051) show the pin numbering layout. A technician can use this page to bench-test and diagnose a faulty power seat switch.
