NOTE: Thunderbird, LTD II and Cougar models use two single switches as a master switch, instead of a multiple master switch. Switches are tested using single window switch test procedures.

Test procedures are performed using a self powered test light or ohmmeter. All tests are performed with switch removed from vehicle. See Fig 1 for reference to pin numbers referred to in test procedures.
With switch removed and in neutral position, there should be continuity between pins one and three, two and five, and four and six.
With switch pushed down, there should be continuity between pins two, four and five, and one and three. Pin six should be disconnected from all others.
With switch pushed up, there should be continuity between pins two, three and five, and four and six. Pin one should be disconnected from all others. If switch does not test correctly, as previously outlined, switch must be replaced.
