1. Preparation

Gather tools and parts needed for repairs.
Ensure the vehicle is on a level surface and securely parked.
Disconnect the battery to ensure safety during electrical work.

2. Check Brake Light Switch

Locate the brake light switch, usually found near the brake pedal.
Disconnect the electrical connector from the brake light switch.
Use a multimeter to test for continuity when the brake pedal is depressed.
If faulty, replace the brake light switch with a new one. Reconnect the electrical connector.

3. Inspect and Replace Fuses

Open the fuse box and locate the fuse associated with the transmission and shifter.
Inspect the fuse for any signs of damage or burn.
If the fuse is blown, replace it with a new fuse of the same amperage rating.

4. Examine Shift Cable

Remove any necessary panels to access the shift cable.
Inspect the shift cable for fraying, kinks, or misalignment.
If damaged, disconnect the cable from both the shifter and transmission, and replace it with a new shift cable.
