Question about 2002 Chrysler 300M

1 Answer

2002 Chrysler 300M, stop lamp & park/horn circuits grounded on load side. What can cause this?

Tried to start the car one day, just clicked. Changed the starter wasn't it. Tried to jump it, voilent spark on positive post. I seperated the two cables on the positive post, both of them spark when I touch the battery cable to them. Trouble shot them with trouble light. Trouble light went out when stop lamp and park & horn fuses are pulled. As for the second cable, that I guess goes to the fuse box on the side of the dash, found the int/bat fuse blown. I replaced it but still not getting any power inside of the car. No interior lights, nothing.

hi ,
remove pos batt cable 1st
I would start examining the door switches since they are a constantly cycling part, Im not exactly sure how many accessories run off the door switches but I would examine the drivers door switch, study how the switch removes from the door, gently pull switch assembly out, being careful not to yank wires loose. remove it and look for arcing marks or soot, try all the doors, then I would disassemble the dome light itself if you cant find it, if you find the short you should reinsulate with thermoheat wrap heated with a hairdryer and maybe even some extra electric tape.

good luck

Clicking??? Probably starter/alternator. does the starter turn? The clicking, is that all you get when you turn the key? Have the battery checked and make sure its holding a charge. If battery holds a charge, its time to have your alternator tested, if the alternator checks, then the clicking may be the starter/soleniod. Places like autozone will check the battery/alt for free, provided you can still drive to get there.

SOURCE: Interior Lights Flash On and Off By Themselves

The interior lights are controlled by a module that gets its information from the sensors in the car door and the switch on the dash that is associated with the dash lights. There is an intermittent short in one of the doors or the module.

Sorry it has to be so vague, but there is not way to know where with out taking some things apart. An intermittent electrical short that can not be duplicated on demand is the hardest thing to diagnose. This is one that needs to go to someone who specializes in electrical diagnosis.

Hope this helps

2007 chevy equinox, running lights are not working, fusses work fine, what else would be the problem?

The problem is your not familiar with electronic's on modern automobiles . Module controlled systems . BCM - body control modules .
The park lamps consist of the park, tail, marker and license lamps. These lamps are illuminated any time the headlamp switch is in the PARK, ON position, or anytime the body control module (BCM) illuminates the headlamps. The PARK fuse in the fuse block - instrument panel (I/P) supplies voltage to both the coil and switch input side of the park lamp relay. The BCM controls the park lamp relay by grounding the park lamp control circuit energizing the relay.

PCB Relays
This vehicle is equipped with the following PCB mounted relays. High Beam, Low Beam, DRL, Fog Lamp, Park Lamp, Stop Lamp, and Horn relay. They are directly soldered to the underhood fuseblock circuit board. A failure of one of these relays will require the whole underhood fuseblock to be replaced.

Your best bet have a qualified repair shop diagnose the problem . Could have DTC'S - diagnostic trouble codes stored in the BCM For circuit faults .
Park Lamp Switch On
B257A 00
B2057A 00
B257A 00
When the headlamp switch is in the OFF position, the body control module (BCM) receives a ground signal through the headlamp switch OFF circuit and an open signal on the park lamp ON circuit. When the headlamp switch is in the PARK or HEAD position, the BCM receives an open signal through the headlamp switch OFF circuit and a ground signal through the park lamp ON circuit.

No on lights tails envoy 2002

Check fuse's in the rear fuse box. LR PARK fuse #14 10A - RR PARK #17 10A - Fuse Block - Rear Beneath the left rear seat
An the park lamp relay #30 in same rear fuse box , Do you know what a BCM - body control module is ?
The body control module (BCM) provides a ground or control circuit to the park lamp relay coil circuit. When the park lamps are turned on, the BCM energizes the park lamp relay. Current flow is from the park lamp relay to the individual park lamp circuit fuses and to their respective park, tail, marker, and license lamps. The front park and marker lamps are grounded at G107 and G103. The tail lamps are grounded at G401 and G402

I have a 2002 chrysler 300m with a 3.5. I started it this morning and it ran rough. I hit the gas and it cleared out. It ran for 5mins then shut off and smoke was coming from under hood. I checked and one...

check for fuses to the ECM
code p2008 refers to intakemanifold air control actuatoror solenoid bank 1---open circuit====causes wiring open circuit--intake manifold air control actuator/solenoid
IF the coil was melted , it is possible that the wiring for the p2008 fault is in the same harness and has burnt through causing the open circuit. or melted out in the connection causing the open circuit.

I have a 300m 2002 it's in park and doesn't

The car is designed that way so the engine can not be over revved when there is no load. Almost all have that feature.

My horn in my car dosent work how can i fix it its a 2001 crysler 300m

Find & unplug the horn & put 12volts to it

If it works & you have no wiring diagrams
to see the entire circuit,then all you can do
is access the horn button & test it.

With a wiring diagram your going approach
things differently,such as testing all inputs &
ouputs at the relay,that will require considerable
knowledge & skill, but save taking the steering wheel
off or apart necessary

Gear shift of f-150 is locked in park. The truck

Is the CHMSL ( Center High Mount Stop Lamp ) working ?
Is it a regular bulb, or did it get changed to a LED ?
If it is a functioning factory type bulb, the shift interlock solenoid is the cause.
Until you can fix the CHMSL or the shift interlock, you can turn the key to the run position ( do not start ), press and hold the brake pedal, shift into neutral, and then start the truck.
Your MY the shift interlock circuit and the brake lamp circuit are the same.
Usually the shift interlock stops working when the brake lamp fuse is blown, or if the bulbs are out ( truck does not see a load on the circuit ).
If LED tail lamps were installed without load resistors, the shift interlock circuit will not work ( looks like a burnt out brake lamp bulb )

Tail light fuse keeps blowing but breaklight and signals still work. I know there may be a short but can't find it.

you could have a bulb filament shorted to ground inside the lamp,or there could be a wire rubbing and shorting out to ground from dash to tail lamps,also remenber the front park lights are on this circuit so could be up front too

No tail lights or dash lights
Click on the link.
Did you check fuse circuit for voltage? Use a test light with headlamp switch on to check for voltage. See the park lamp relay, I'm not saying the relay is faulty, but, you might be able to use jumper wire on load side of relay, if lamps work, the problem is on control side of relay, for some reason.
The load side of relay is that line with arrowhead. There could be other issues.

2002 chrysler 300 wont go into park

It sounds like your linkage is binding. Hold the brake down and shift between drive and reverse a few times and then into park. I had the same problem with my 2002 300m. It went away after working the shifter a number of times. DO NOT FORCE IT.
