The right side will have a burnt out/ missing light bulb.
Yes look in your manual it will show you were it is but if your having a problem its more likely a wire than the switch.
You have a problem with your ground. A weak ground will always cause this type problem.
to the left, right, or under the steering wheel.
More than likely you have a burnt out bulb at the front signal light, rear signal light, or brake light on the right side.
Check the fuses on the car, or the signal bulbs.
My next guess, in this form of troubleshooting, would be a wiring harness problem / fuse problem / pass through or plug problem. IE The computer is telling something to work, but the signal is not getting to the right place.
change the flasher
could be a bad ground
Check the bulbs. A failed bulb can often cause the signal to stop working on that side.
remove passenger side signal front light first then passenger headlight and horn should be right behind below the side passenger signal light!
Replacing the non-working bulb for left turn should resolve the problem and it will stop the cops from pulling you over too.
The horn is behind the right headlight. It looks like a black drum or rubber plate. * on my '93 it is mounted on the firewall passenger side behind the intake manifold. The horn is behind the right turn signal. If you remove the right yellow turn signal light, it's right there.
