Diagram for fuses

I would first check fuses. Make sure you have power to and from the bulb sockets. If not power make sure wiring, grounds and wiring connection are good. Verify you have power to bulb socket, may have bad socket but unlikely all went out at same time. My last thought make sure you have power to and from switches.
Not sure what vehicle you have but these are my thoughts in general.

Some vehicles may have a fuse for blinker and even separate fuses for high and low beams. You could have relays for blinker, low beam and third relay for high beam.
If you go to google and put your year make and model also put fuse box diagram or owners manual you may find your fuse box diagram.

You may have several link pop up if you look through them you may find one which works.
Hope this helps.

Use wiring that is already supplying tailights at rear.

The tail lights are also called parking lights.
There is a 10amp fuse for each rear parking lamp. The fuses are in the rear fuse box. Your owner's manual will tell you where that fuse box is located.
The fuses get power from a park lamp relay.

The owners manuel should have a diagram of the fuse box.

You should check out www.reliable-store.com they have info on repair,
service, wiring diagram, electrical diagram, fuse diagram, troubleshooting, PCV, gear box, owner's/service/repair/parts manual, fault codes, error codes, etc everything on all vehicles. must check it out

no, sorry . but i do have a suggestion that might help. do the taillights work? if so check the brake light switch on the brake pedal. also , does the high mount light work and not the rear ones? if so you may want to check the turn signal switch to make sure there is voltage on that circuit.

Check underhood fuse box; can download your manual from this link: chrysler.com/en/owners/manuals (page 315 and next).

Hope this helps (remember to rate this answer).

No Turn Signal Operation (blinker)The turn signal lights in your car are a basic electrical system that controls the front and rear blinker lights to alert the intended direction of the vehicle. We have listed some of the most common problems and repair troubleshooting tips below:
Troubleshooting Procedure
To start troubleshooting this problem:

• Turn the key to the on position (do not start engine)
  
• Inspect the system fuse located in the fuse panel and replace if needed. If you cannot find the location of the blinker fuse consult your owner's manual or an online repair manual
  
• When a blinker flasher fails it can cause blinker lights to say on, not blink, or not go on at all. To test the blinker system flasher, remove the flasher unit and insert a jumper wire between the two terminals. If blinker stays on in both directions without blinking, replace the flasher. If you cannot find the location of the blinker flasher consult your owners manual or an online repair manual.
