How to change the Turn Signal Assembly? on 2001 Mitsubishi Galant

The turn signal assembly will not lock when turning the signal on ( i.e. when I want to turn left and push down; the arm on the assembly pops back up and the same for the right). This also makes the hi beams to always be on even when the car is turned off. I have a coin holding it in place now so that the hi beams will not drain the battery.

This is most likely a bad turn signal switch.
