Power Window Switch
Remove the switch. See POWER WINDOW SWITCH under REMOVAL & INSTALLATION. Using an ohmmeter, test the window switch for continuity in all positions listed. See WINDOW SWITCH CONTINUITY table. For identification of window switch terminals, see Fig 1 - Fig 2 .
To test the left front down and express down switch position, connect pin No. 4 to ground and pin No. 12 to a 12-volt source. Using a voltmeter, measure for voltage from pin No. 13 to ground.
To test the right front down and express down switch position, connect pin No. 4 to ground and pin No. 12 to a 12-volt source. Using a voltmeter, measure for voltage from pin No. 3 to ground. If the correct results are not obtained, replace the switch.
