- Disconnect driver's seat adjuster memory module 6-pin connector C318 (Black). Disconnect 23-pin connector C317 (Black) from power seat motor pigtail. Connect connectors C318 and C317 together. If power seats do not operate properly, go to next step. If power seats operate properly, replace driver's seat adjuster memory module.
- Using test light, backprobe between power seat switch connector terminals "L" (Orange wire) and "E" (Tan wire). If test light glows, go to next step. If test light does not glow, check for poor connection at Tan wire. If connection is okay, replace power seat switch.
- Backprobe between power seat switch connector terminals "L" (Orange wire) and "D" (Light Green wire). If test light glows, go to next step. If test light does not glow, check for poor connection at Light Green wire. If connection is okay, replace power seat switch.
- Backprobe between power seat switch connector terminals "A" (Black wire) and "D" (Light Green wire). Move power seat switch lever to back position. If test light glows, go to next step. If test light does not glow, check for poor connection or short to ground in Light Green wire. If circuit is okay, replace power seat switch.
- Backprobe between power seat switch connector terminals "A" (Black wire) and "E" (Tan wire). Move power seat switch lever to forward position. If test light glows, go to next step. If test light does not glow, check for poor connection or short to ground in Tan wire. If circuit is okay, replace power seat switch.
- Check for poor connection, open, or short to ground in Light Green wire and/or Tan wire between power seat switch and forward/back motor. If circuits are okay, replace forward/back motor.
