Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is on a flat surface and the parking brake is engaged.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect Brake Switch

Remove the lower dash panel to access the brake switch.
Check the brake light switch for continuity using a multimeter.
If faulty, replace the brake light switch:
- Disconnect the electrical connector.
- Remove the switch from its mounting.
- Install the new switch and reconnect the wiring.

3. Check and Replace Shift Interlock Solenoid

Locate the shift interlock solenoid near the shifter assembly.
Disconnect the electrical connector.
Test the solenoid for proper operation using a multimeter.
If defective, remove the solenoid by unscrewing its mounting bolts and installing a new one.
Reconnect the electrical connector.

4. Inspect Shifter Assembly

Remove the center console cover to access the shifter mechanism.
Check for any debris or object obstructing the shifter movement.
Lubricate moving parts if necessary and ensure everything is properly aligned.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the vehicle and press the brake pedal to attempt shifting out of park.
Test the operation of the shifter through all gears.
