Turn signal turns not working?

Not sure exactly what "freak out" means but you may want to ensure the ground wiring and other connectors are tight and connected properly at the switch you worked on.

The left signal working does not necessarily mean the flasher is good. Left and right have different circuits within. Do all the lights turn on when the hazard lights are turned on?

I am confused with the situation and let us put it in proper perspective so that I under the problem correctly.

1. LH signal flashes when RH is turned on. This is to mean the signal switch only works the LH when when it it turned to right or left? If yes, you could have a bad siwtch.

2. Less than battery voltage can mean a poor connection somewhere and for the flasher relay, the correct voltage is important fo it to work correctly.

I tried checking through the circuit schematics in our database and is as confused as before. Not easy when there are 3 diagrams to link. Maybe I should try printing them out to check.

There are 2 relays in the circuit. You mentioned swapping, was both swapped or only the hazard flasher? In the underdash fusebox there is another side marker flasher relay.

Check out the side marker relay. Seems that is the only component that can cause the symptoms described.
