Are you having any other electrical or electronic issues? Check the voltage at the jumper post located under the red plastic cover under the hood. Use the engine as the ground. Report back your findings.

These cars are rolling computers and whacky voltages cause whacky issues.

12.4VDC is good but not optimal. The external lights are all controlled by the LKM. I’d fix the wiring in the trunk lid to see what happens.

do you think a bad ballast could cause a problem with the blinkers, i’m thinking it could be a ballast because of the passenger side light not warming up

Disconnect the ballast and see what happens.
