Neutral Safety Switch

WARNING: This page is about a different car, the 1988 Jeep Wrangler, 1988 Jeep Wagoneer, 1988 Jeep Grand Wagoneer, 1988 Jeep Comanche, and 1988 Jeep Cherokee. However, it is still accessible from the selected car via links, so may be relevant.
  1. Switch combines functions of neutral safety switch and back-up light switch. With transmission linkage properly adjusted, switch should allow starter operation in "P" and "N" only.
  2. To test switch, remove wire connector and test for continuity between center pin of switch and case. Continuity should only exist when transmission is in "P" or "N".
  3. Check for continuity between 2 outer pins. Continuity should exist with transmission in "R" only. There should be no continuity between either outer pin and transmission case. If any o these conditions are not met, the switch should be replaced.
  4. To replace switch, unscrew from case. Move selector lever to "P" and "N" positions and check that switch operating fingers are centered in switch opening. Install switch and new seal in case. Check fluid level and add as needed.
