• Q: How to Service and Repair the Shift Interlock Solenoid on 2009 Mercury Grand Marquis?

  A: The first step for repairing or servicing the Brake Shift Interlock Actuator requires you to deplete the back up power source to stop air bag activation. Disconnect the battery ground cable and wait for at least one minute and verify that all auxiliary battery sources and power systems have no power. The first step involves removing the Supplemental Restraint System (SRS) steering column Clock Spring and the second step requires removing the three mounting bracket bolts to detach the bracket from the steering column until torqued to 8 Nm (71 lb-in) before reinstallation. After releasing the clip which anchors the Brake Shift Interlock Actuator (BSIA) you can slide the BSIA down and remove the park position switch together with the BSIA from its cavity. The installation process completes when performing the opposite steps of removal.
