Some technicians may find that after installation of a Sit-N-Lift(TM) system, the system buzzer sounds and the vehicle will not shift out of park.
If the proper installation instructions are not followed, it is possible to bend the limit switch bracket and possibly damage the limit switch. If this occurs,
the seat does not retract the full travel and, therefore, will not make contact with the pivot switch. In this case, the seat does not lock, sounds the buzzer,
and will not allow the vehicle to shift out of park.
The limit switch bracket has been redesigned to provide better protection to the limit switch. To correct this concern, follow the procedure below to
replace the limit switch bracket. If the limit switch casing has been damaged, it will also be necessary to replace the limit switch.
1.
Position the seat so that it is extended out of the vehicle.
2.
Remove the upper seat trim.
3.
Remove the bolts from the limit switch bracket.
4.
Remove the bracket with the switch from the seat base.
5.
Remove the switch from the bracket.
6.
Disconnect the electrical connector.
Important:
The screws that hold the limit switch to the bracket will have to be installed from the opposite side due to the redesign of the bracket.
7.
Reinstall the limit switch to the new bracket.
8.
Connect the electrical connector to the limit switch.
9.
Install the tie-wrap through the holes at the bottom of the bracket, adjacent to the connector to retain the connector to the limit switch.
