Master Switch

WARNING: This page is about a different car, the 1992 Mercury Topaz, 1992 Ford Tempo, 1991 Mercury Topaz, and 1991 Ford Tempo. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: The switch should be oriented so that the raised portion of the switch knob is to the right and you are looking at the five terminals.
  1. With switch in the NEUTRAL position, there should be continuity between terminals No. 1, 2, 3, 4, 5, 6, 7, 8 and 9, and terminals No. 10 and 11. With the raised portion of all switch rocker knobs pushed (to close the windows), there should be continuity between terminals No. 1, 3, 5, 7, 10 and 11, and terminals No. 2, 4, 6, 8 and 9. See Fig 1 .
  2. With the depressed portion of all switch rocker knobs pushed (to open the windows), there should be continuity between terminals No. 1, 3, 5, 7 and 9, and terminals No. 2, 4, 6, 8, 10 and 11.
  3. With the lock out switch button depressed into its detented position, terminal No. 11 should not have continuity with any other terminal. If the switch does not test as stated, replace the switch assembly.
