How do I fix gear indicator light on my 2007 scion tc?

To fix the gear indicator light on your 2007 Scion tC, first check the vehicle's fuses, as a blown fuse can cause the light to malfunction. If the fuses are intact, inspect the gear shift assembly and wiring for any damage or loose connections. You may also want to reset the vehicle's battery by disconnecting it for a few minutes, which can sometimes resolve electrical issues. If the problem persists, consider consulting a mechanic for further diagnosis.
