Passenger side turn signals (front and back) not working

Everything else on the car is working fine. We replaced both of the bulbs and that didn't fix the issue. We checked the fuses and there doesn't appear to be a blown fuse. Our mechanic friend said it may be an issue with the relay, but the research I've done indicates that there is not a relay for the turn signals on this vehicle. What could be causing the turn signals to not work?

Welcome to 2CarPros.

If the bulbs are correct and good and there is power (fuses good), the next thing to check is the switch itself. To check it requires it to be removed and then to check for continuity in the different positions.

Here are the directions for removal and replacement. The attached pictures correlate with the directions,
