Sounds like you have a blown fuse. Check the fuse box.
its either the flasher or the turn signal switch
Sounds to me like the turn signals and the heater fan may be on the same fuse?? Jack
it is most likely the turn signal flasher
Replace the Flasher Relay.
cuz there broke.. try flasher or turn signal
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.
One of four things can cause a turn signal not to work. Either the turn signal switch assembly, a bad bulb, a bad fuse, or a bad turn signal flasher.
1995 hond accord in cold weather turn signal does not work?
turn signal switch u need
These are two separate circuits. They use separate flasher relays. They use separate fuses. They use separate switches. Check your signal fuse and signal flasher relay.
Bad ground.
Typically if the turn signal lamp on the dashboard stays on (i.e. does not blink), it means you have a burned out turn signal bulb on either the front or rear of the car. This is especially true if it happens only on one side (i.e. left or right turn signal). If the problem exists on both sides of the vehicle, check your flasher unit.
