Help I have an wiring issue

it was a 12 dollar part and was loose. i had to get in there and change it out anyways. I was about to tear out the turn signal switch cause it doesnt work. but Ive been waiting to do so till i get a floor shift column. im going to take apart my front side marker lights and see what happened with them. my back side markers dont work either for some reason. they use to. but the car sat for over a year.
