replace the turn signal switch in the steering column

Sounds like the brake light switch has a problem. Located above brake pedal and activated with the brake pedal arm. Check for power going in and coming out when you apply the brake.

SOURCE: Have hazard lights but no running or turn signals

sounds like you need a combo flasher assembly..located in fuse block inside vehicle under steering column..there may be a plastic cover under dash you have to remove to see fuse block..large black relay that plugs into fuse block..if you pick up a new one,you will see what it looks like..available at dodge dealer..combo flasher or drl/signal relay

You need to replace the flasher module, this is the module that controls the "Blinking" function of the lights, its a mostly a common part that you can get at any auto parts store for less than 10 bucks and is located in the Fuse panel under the dash, its round in shape in one corner of the panel. mostly they are green in color.

I had this problem, and to be honest, it happened to the left side about a week later...it's the board that the bulbs plug into...it's a very common problem with this model. So popular that you can normally get the socket board off the shelf at a parts store! it's extremely simple to replace, and I replaced all the bulbs at the same time!
