Trip Odometer Does Not Reset (Astro & Safari)
- Check for an inoperative cluster control switch or wiring. To do so, disconnect large 17-pin connector from cluster. Measure resistance between pin No. 5 and ground.
- Resistance should be zero (0) in one position, and open in the other. If switch does not respond as indicated, repair Light Green/Black wire between cluster and switch, the switch, or the Black wire from switch to ground.
- If switch and related wiring are okay, replace inoperative instrument cluster.
