BAD BRAKE LIGHT SWITCH AT TOP OF BRAKE PEDAL
Hey E==The running lights have a module which may be bad. Good luckJoe
the alarm
I would check the running lights for one with a short. I had the same sort of thing with my trailer and I spent way to much time troubleshooting the brake and signal wires. Turns out a running light bulb connector was grounding out on the trailer and messing it all up.
If the brake lights stay on when the car is not running on most vehicles, including the 1994 Dodge Intrepid, there is probably a short somewhere in the wiring to the brake lights. The first place to investigate this problem would be the wires along the firewall that control the brake lights. Also, check the brake light switch above the brake pedal.
You need a new multi-function switch (blinker switch) . The current for the brakes goes through it
The most likely cause is a bad brake light switch (if none of the brake lights illuminate) but if its only one of the brake lights, try changing the bulb. Even if they still work as running or turn lights because they have a double filament and may still work partially, but not as brake lights.
I have run into the same thing with this kind of car. On the steering column at the top they have a switch that will turn the running lights on or turn them off. check the switch you may have hit it and turn it on.
