Convertible Top Inoperative

  1. Check system operation. If top does not operate properly, go to next step. If top operates properly, check operation while wiggling wiring and connectors.
  2. Turn ignition switch to RUN position. Using test light, backprobe between 8-pin convertible top switch harness connector terminal "F" (Brown wire) and ground. If test light illuminates, go to next step. If test light does not illuminate, go to step  12 .
  3. Using test light, backprobe between 8-pin convertible top switch harness connector terminal "F" (Brown wire) and "H" (Black wire). Press convertible top switch to DOWN position. Using test light, backprobe between 8-pin convertible top switch harness connector terminal "F" (Brown wire) and "D" (Black wire). Press convertible top switch to UP position. If test light illuminates both times, go to next step. If test light does not illuminate both times, go to step  5 .
  4. Using test light, backprobe between 8-pin convertible top switch harness connector terminal "A" (Purple wire) and "E" (Gray wire). Press convertible top switch to UP and DOWN positions. If test light illuminates both times, go to step  6 . If test light does not illuminate both times, go to step  7 .
  5. If test light illuminated in one position, go to step  13 . If test light did not illuminate at all, go to step  14 .
  6. Using test light, backprobe between 2-pin convertible top motor harness connector terminals "A" (Gray wire) and "B" (Purple wire). Press convertible top switch to UP and DOWN positions. If test light illuminates both times, go to step  9 . If test light does not illuminate both times, go to step  11 .
  7. Check for poor connection at convertible top switch. If connection is okay, go to next step. If problem is found, repair as necessary. After repair, go to step  24 .
  8. Replace convertible top switch. After repair, go to step  24 .
  9. Check for poor connection at motor. If connection is okay, go to next step. If problem is found, repair as necessary. After repair, go to step  24 .
  10. Replace pump/motor assembly. After repair, go to step  24 .
  11. Repair open or short to ground in Purple wire or Gray wire between convertible top switch and motor. See WIRING DIAGRAMS  . After repair, go to step  24 .
  12. Repair open in power feed circuit. See WIRING DIAGRAMS  . After repair, go to step  24 .
  13. Repair open or poor connection in Black wire between affected switch terminal and splice 232, located in the instrument panel harness, about 2.8" (70mm) from parking brake switch breakout. See WIRING DIAGRAMS  . After repair, go to step  24 .
    NOTE: Some rental agency vehicles have Regular Production Order (RPO) ETA, which prevents top operation unless transmission is in Park. RPO label is located on driver's door jamb.
  14. If vehicle is equipped with ETA, go to next step. If vehicle is not equipped with ETA, go to step  20 .
  15. Ensure vehicle is still in Park and ignition is on. Access power top relay located behind right side of instrument panel. Connect a test light (backprobe) between power top relay terminal C2 (Brown wire) and ground. If test light illuminates, go to next step. If test light does not illuminate, repair open in Brown wire between power top relay terminal C2 and power feed circuit. See WIRING DIAGRAMS  . After repair, go to step  24 .
  16. Connect a test light (backprobe) between power top relay cavity terminals C2 (Brown wire) and A1 (Tan/White wire). If test light illuminates, go to next step. If test light does not illuminate, go to step  21 .
  17. Connect a test light (backprobe) between power top relay terminals C2 (Brown wire) and A2 (Black wire). If test light illuminates, go to next step. If test light does not illuminate, repair open or poor connection in Black wire between top relay terminal A2 and ground G202, located on right kick panel. After repair, go to step  24 .
  18. Connect a test light (backprobe) between power top relay cavity terminals C2 (Brown wire) and C1 (Black wire). If test light does not illuminate, go to next step. If test light illuminates, repair open or poor connection in Black wire between splice 232, located in the instrument panel harness, about 2.8" (70 mm) from parking brake switch breakout and power top relay cavity terminal C1. After repair, go to step  24 .
  19. Replace power top relay. After repair, go to step  24 .
  20. Repair open or poor connection in Black wire between splice 232, located in the instrument panel harness, about 2.8" (70mm) from parking brake switch breakout and ground G202 located on right kick panel. After repair, go to step  24 .
  21. Turn ignition off. Disconnect Black, 5-pin Park Neutral Position (PNP) switch connector. Using a DVOM, check continuity of circuit between power top relay terminal A1 (Tan/White wire) and PNP switch harness connector terminal "B" (Orange/Black wire). If continuity exists, go to next step. If continuity does not exist, repair wiring as necessary. See WIRING DIAGRAMS  . After repair, go to step  24 .
  22. Check continuity between PNP switch terminals "A" and "B" with switch in park and neutral positions. If continuity exists in both positions, go to next step. If continuity does not exist in both positions, replace PNP switch. After repair, go to step  24 .
  23. Repair poor contact or open on Black/White wire between PNP switch harness connector terminal "B" and ground. See WIRING DIAGRAMS  . After repair, go to next step.
  24. Reconnect all connectors an components. Recheck system operation.
