check fuses
signal lights not working.
I would check the fuses in your 2003 Intrepid. If you had a bad battery, the lights and hazards would be dim. The heater, turn signal and windows may be on the same fuse.
When parts stop working, a diagram can help pinpoint the cause. The diagram for the turn signal lights on this car can be found in its maintenance manual.
Either hand signal or check and replace your fuses and turn signal bulbs.
A blown fuse or burned out bulb
When the signal lights are not working on a car, there are a couple of things that could be going on. One could be that the bulb needs to be replaced. The other possibility is that the signal relay needs to be replaced.

It's the turn signal indicator-located behind the hazard lights.You have to take it out and replace it.
