Pulser Test

  1. Reconnect the 6P connector to the window motor.
  2. Check for voltage between the terminals: There should be battery voltage between the No. 6 (+) and No. 4 (-) terminals when the ignition switch ON (II).
  3. If there is no battery voltage, check for an open in the wire.
  4. Check the voltage between terminals:
    • Connect an analog voltmeter between the No. 5 (+) and No. 4 (-) terminals, and run the window motor at down or up. The voltmeter needle should move back and forth alternately (a digital voltmeter should show the average voltage between 0-5 V).
    • Connect an analog voltmeter between the No. 3 (+) and No. 4 (-) terminals, and run the window motor at down or up. The voltmeter needle should move back and forth alternately (a digital voltmeter should show the average voltage between 0-5 V).
  5. If the voltmeter does not indicate as specified, replace the window motor.
