Change the rear turn signal bulb - 2011 Jeep Patriot

Lamp, bulb, supply and ground obviously ok as the hazards work - I suspect the hazard switch might be faulty or something like a dodgy multiway connector onto the switch...

Change the bulb on the passenger rear.

Peel back the trunk lining to reveal three wing nuts. Remove wing nuts to pull lens cap away from car. To remove bulb socket push on the rectangular button (the release) while pushing on the end of the socket to unlock and spin counter clockwise to release. pull out old bulb and reinstall lens cap.

First,

1. Turn the engine off and open the hood. Pry up the two fasteners from the radiator air baffle with a flat head screwdriver. Move the baffle to the side to access the top of the headlight case.
   
2. Step 2 Pull up the two metal rods behind the headlight case. These secure the case to the car. You may need your pliers to pull them up.
   
3. Step 3 Gently pull the headlight case out to access its rear. On the rear, you will find several black dust covers. Twist off the dust cover closest to the fender (the outward dust cover) to access the turn signal bulb.
   
4. Step 4 Turn the bulb module counterclockwise to release it. Unplug the electrical connector from the bulb module. Connect the new bulb to the electrical connector (don't touch the glass with your hands; hold it by the plastic piece). Insert the bulb module in the turn signal housing, turn it clockwise and screw the dust cover back on.
   
5. Step 5 Insert the headlight case in the mount. Push the pins back down to secure it. Position the radiator baffle in its place and insert the fasteners.

The turn signals flash depends on each and every bulb working correctly. When one bulb fails, you will notice a change in the flash frequency, as you describe.

Replace or repair the bulb that is not working, and you should be good to go.

The turn signal switches are known to go bad, try to use the turn signal switch and jiggle the lever after clicking to the left turn. Replace signal switch assembly.

You have to take the whole assembly off to change the bulbs. There are two screws next to the taillight when you lift of the rear hatch

open the hatch there should be two screws that hold on the lense, twist the bulb holders and remove
