As some background info, when I bought the car the headlights didn't work but the brights and turn signals worked great. I’ve since replaced the multifunction switch and the headlights work now but turn signals don’t.

Also have bought an aftermarket radio and it turns on but no sound, have already checked for the orange and black wires in the cluster of wires that run along passenger side and they’re connected and intact. Any advice is appreciated.

 

For the turn signals, I'd break out the wiring diagram and a multimeter. Id probably start at the stalk itself and work from there depending on what you read at its wiring.

For the radio, has it been confirmed to work (wasnt sure if new or used)? Id probably pop it out, direct wire the hots and ground and plug in an external speaker. Having worked car audio in the past, I have seen probably a dozen aftermarket head units dead out of the box. Ultra tiny %, but it is possible.
