A few notes:
Check your fuses first.

Question:
What's the connection between the hazard switch and the turn signals?

Answer:
The turn signal circuits are rerouted through the hazard switch = Left/Right join to flash together.

Question:
I used my hazard switch (road trip), the turn signals don't work now, is there a way to fix this?

(The hazard switch can fail so that one or both turn signals do not work).

Answer:
#1. Try cycling/exercising the hazard switch a few times and see if the issue is gone.
#2. You will need a pocket knife or small screwdriver. Remove the switch. Disassemble the switch, arrange the internal rockers to the off position (note on paper which pins are bridged), re-assemble and test the turn signals.
If your repair worked ignore the following.
If the repair failed, get two short pieces of wire with the ends stripped to fit the wire harness switch pin holes, take your note on paper of which pins are bridged in the off position, and bridge each pair with one of your wires, test the turn signals.
