So first thing I did when I got my 05 was replace the turn signal switch that was broke off, I replaced it with an acdelco one from Amazon. All blinkers work fine except the front passenger side so I replaced both bulbs, right and left. The passenger one still doesn't work. So I'm looking for possible answers.

I can do a couple of things on a car, but no way a mechanic

When I bought my car, the driver side turn signal would light up, but not the parking light. In my case it was the wiring in the headlight. I swapped the wiring with one from the junkyard. It had a bad connector. Didn’t look bad, but was burned where the bulb contacts.

If you don’t have something simple like a bad connector, it could be a bad switch or even the body control module. The BCM is what controls the lights. You say you replaced the switch with no change, correct?

Yup, brand new switch. The parking light comes on, but not the auto or blinker. Aside from that, left blinker is perfect, both high and low beams and tail lights and reverse lights are perfect.
