How to Fix a Non-Functioning Right Turn Signal?

First, check if there is power at the hot wire terminal of the flasher relay. If there is no power, inspect for any open circuit between this wire and the power source. Open the cover of the flasher relay and check if the coil and resistor are intact. Press the movable contact; if the turn signal does not light up when the contact is closed, you can use a screwdriver to short-circuit the contact. If the light turns on, it indicates that the contact is oxidized.
When my right turn signal suddenly stopped working, I've dealt with it myself a few times. The most common cause is a burnt-out bulb—it's usually located inside the headlight or taillight housing. Open the hood, locate the turn signal assembly, and check if the bulb has turned black or the filament is broken. If the bulb is intact, it might be a blown fuse; go to the fuse box on the driver's side, refer to the user manual for the corresponding turn signal fuse location, pull it out and check if it's blown. Replacing it only costs a few bucks. But if all these are normal, then you'll need to check for wiring issues, like a loose connector or aged wires causing a short circuit—that might require a repair shop to diagnose with tools. Remember, driving without a functioning turn signal is very dangerous as it affects others' judgment of your intentions. If you can't fix it temporarily by the roadside, turn on the hazard lights to alert others for safety.
