Re: My headlights wont turn off on my 2003 dodge intrepid
I own the same year make and model. The headlights are supposed to stay on for a few minutes if you shut them off after shutting off the engine. This is a safety feature. These are the headlights only. If the lights, side markers and taillights stay on, then the issue is most likely the switch. You will have to pull the switch and disconnect the wiring harness to confirm this. If the lights go out, then the switch is bad.
However, if the lights don't go out, or the headlights never shut off until they drain the battery, you may want to take the car in to get diagnosed. There could be an issue with the body control module or wiring. Most likely, it is the switch as Chrysler uses the cheapest parts for their switches, but I would check it first and not swap parts. All you have to do to check the switch is pull the bezel it sit in out of the dash. The switch is held in with two screws.
a 6ya Mechanic can help you resolve that issue over the phone in a minute or two.

Do you know anything about automotive electronics ? Electronic control modules .
Headlamp ON/OFF control is determined by the body control module (BCM) by a signal on the headlamp switch on input circuit when the headlamp switch is in the HEAD position. When the headlamp switch is in the AUTO position, the BCM determines headlamps ON/OFF by the voltage from the ambient light sensor.
If the headlight switch is left in the ON position, the inadvertent power control feature will turn OFF the headlights approximately 10 minutes after the ignition switch is turned to the OFF position. If the driver places the headlight switch in the ON position after the ignition switch has been turned OFF, or if the ignition switch is in the ACCY position, the headlights will remain ON until turned OFF or the battery runs dead.
The high beam indicator is illuminated when the instrument cluster receives a GMLAN serial data message from the BCM that the high beams are illuminated.
The high beam headlamps receive voltage from the headlamp high relay located in the underhood fuse block. The BCM controls the relay on the headlamp high beam relay control circuit. High beam control is determined by a signal on the headlamp dimmer switch signal circuit from the multifunction switch. When the headlamp dimmer switch signal circuit is grounded, the BCM grounds the headlamp high beam relay control circuit, illuminating the high beam headlamps. The right and left high beam circuits are independent and are fused independently in the underhood fuse block.
Low Beams - Standard
The low beam headlamps receive voltage from the headlamp low beam relay located in the underhood fuse block. The BCM controls the relay on the headlamp low beam relay control circuit. Low beam control is determined by a signal on the headlamp dimmer switch signal circuit from the multifunction switch. When the headlamp dimmer switch signal circuit is open, the BCM grounds the headlamp low beam relay control circuit, illuminating the low beam headlamps. The right and left low beam circuits are independent are fused independently in the underhood fuse block.
Hooking up a factory scan tool an checking DTC'S - diagnostic trouble codes would be the very first step in trouble shooting this problem .
DTC B257A 00: Headlamp Switch Input Signal Mismatch
DTC 2575 00: Headlamp Control Circuit
Do you mean it won't crank at all, or cranks but does not start. If the first, turn on headlamps and try to start. Do headlights dim? If not, you may have bad battery connections, bad solenoid, bad neutral safety switch. If lights dim, bad battery, connections, solenoid or starter motor.
The headlamp may be grounded. Check for loose wires on the wiring to the headlight that may have touched the body of the car. Otherwise it may have been rewired and was connected to the 'hotwire' which provides power even when the key is on OFF.
Sounds like either a headlight switch or a broken ground. Did you lose both the hi and low beams? Do your parking lights work? The headlight switch outputs to the hi/low selector on the column. If both hi and low beams are out I would check output voltage from the switch. Sounds ike that make be your issue. Good luck and let me know if I can assist further.
On each headlamp, you need to remove the screws holding the headlamp the
the car (2 screws per headlamp)
Then pull the lamp out and change the bulbs.
Dont touch the new bulbs with your hands, use the plastic bag they came in
(but remove the bag after install!!!)
I too have a 2002 dodge Intrepid, after 10 minutes of driving the car, when i make a stop it won't shift properly, in order to make it shift, i have to turn the ignition off and back up again!
If anyone can help me locate the TCM that would be great.
I'm ready to drive it off a cliff
Thanks in advance!
