  Q: How to Service and Repair the Shift Interlock Solenoid on Lincoln Town Car?

  A:

  A safety precaution exists before servicing or repairing the brake shift interlock actuator which involves draining the back up power supply to prevent undesired air bag deployment. You should disconnect the battery ground cable and wait for at least one minute. Additionally, suspend all auxiliary batteries and power supplies if your vehicle has them present. Start the task by removing the lower steering column finish panel through screw removal before putting the parking brake release handle out of range and afterward removing the screw and pulling the panel outward to detach the retaining clips. The procedure begins by removing the lower steering column opening finish panel reinforcement where five screws need removal before proceeding to the four screws securing the instrument panel reinforcement brace. Move the selector lever indicator cable to a safe position by freeing its screw and detaching the connection. First lower the steering column by taking out the four nuts before uninstalling the three bolts which detach the shift lock actuator from the transmission shift selector position insert. A disconnect of electrical wires enables the removal of both the shift lock actuator and the transmission shift selector position insert. The install procedure includes executing the removal steps in reverse order.

  Q: How to Address Issues with the Shift Interlock Solenoid in a Lincoln Town Car?

  A:

  A proper servicing and repair of the Brake Shift Interlock Actuator begins by disconnecting the battery ground cable followed by a one-minute wait for back up power depletion. The first step requires removing the steering column Clock Spring after which the technician should replace the Clock Spring mounting bracket bolts until they achieve 8 Nm (71 lb-in) torque. Releasing the clip which holds the Brake Shift Interlock Actuator (BSIA) allows you to slide the BSIA downward until you extract the BSIA assembly from the cavity after removing the park position switch. The installation process of the BSIA should be done by reversing the order of removal steps.
