Need help on troubleshooting my right turn signal lights!?

The turn signal solenoid is broken It happened to my car I also have a early 90's GM car. When they go bad either the signal won't work at all or just one side will get stuck. It was probably just a coincidence. Try to turn the signal on and off a couple of times to see if that makes it work again. if that works than your signal solenoid is broken. Get the ones that have the louder clicking sound they last longer.
