Outside Mirror Switch

  1. Check 15 amp courtesy lamp fuse, replace if blown. Using putty knife or similar tool pry mirror switch out of housing.
  2. Remove connector at switch and check for voltage across circuits 54 LG/Y and 57 BK. If no voltage, check 54 LG/Y to a good ground. If still no voltage, trace problem in 54 LG/Y wire.
  3. If voltage is present in above tests, check switch by jumping across the appropriate terminals using the logic chart. See Fig 1 .
  4. If mirrors operate using the chart, replace the switch. If mirrors do not operate, problem is in mirror or wiring harness to mirror.
