Cluster Display Does Not Switch Between Total & Trip Odometer (Astro & Safari)

  1. Check for an inoperative cluster control switch or wiring. To do so, disconnect large 17-pin connector from cluster. Measure resistance between pin No. 3 and ground.
  2. Resistance should be zero (0) in one position, and open in the other. If switch does not respond as indicated, repair Light Green wire between cluster and switch, the switch, or the Black wire from switch to ground.
  3. If switch and related wiring are okay, replace inoperative instrument cluster.
