The full open switch is a normally closed micro-switch. To test proper operation of the full open switch proceed as follows;
- Using an ohmmeter, test continuity of the switch with the liftgate in the full open position. Continuity should be present. If OK go to Step 2. If not OK, replace the switch.
- Test continuity of the switch while depressing the full open switch contact arm. Continuity should not be present. If not OK, replace the switch.
