Disconnect left forward/back motor connector. Connect a fused jumper between battery voltage and either terminal of forward/back motor. Connect a second fused jumper between other terminal of forward/back motor and ground. If motor runs, go to next step. If motor does not run, go to step 11 .
Check for open or short to ground in Tan wire between Memory Seat Module (MSM) and left forward/back motor. If circuit is okay, go to next step. If faulty circuit is found, go to step 12 .

Disconnect left seat switch Gray, 16-pin connector. Disconnect MSM Blue, 32-pin connector C2. Using DVOM, measure resistance of Tan wire between seat switch connector terminal "E" and MSM connector C2, terminal C5. See Figure and Figure . If resistance is less than 5 ohms, go to step 10 . If resistance is greater than 5 ohms, go to step 14 .
Disconnect left seat switch connector. Disconnect MSM connector C2. Using DVOM, measure resistance of Light Green wire between seat switch connector terminal "B" and MSM connector C2, terminal C6. If resistance is less than 5 ohms, go to next step. If resistance is greater than 5 ohms, go to step 15 .
