Dear wapirc-- I saw a car with the same symptoms as your 2002 Chrysler 300M in the movie "Close Encounters of the Third Kind." But, I doubt that flying saucers are your problem. You obviously have an electrical problem and need a hands on diagnosis. These problems may be very minor, but the require an experienced technician to pinpoint and repair them. Take it to a mechanic you can trust. Good luck from Bovan.

Sometimes all the lights will come on and stuff will go crazy , when the charging system stops working. Check and see if the alternator is working properly. When the voltage drops due to not charging , warning lights will come on for all sorts of things, this happens when relays cannot be activated due to low volts and the systems computers will turn on lights indicating problems .

Same problem 2000 300M, replace the light switch, meanwhile, take or turn the light switch OFF the "AUTO" selection. you will have to use it like the old days, turning them on and off, until the switch is replaced

Sounds like something is corroted. Check fuses, and battery cables, if corroted, poor some coke over the white corroted cables, eventually need battery replacement, buy a maintenance FREE batt.

Exactly, I need help. My fuses are great. My flashers, turn signals, and interior dome lights are not working. Has anyone had luck repairing this issue?

Dear JW49 - have you ever SEEN the battery in a 300M? I can't find it. I also suffer from random light flashings, seats not warming, etc. If it starts honking on its own I'm leaving it on the side of the road.

Ive seen and heard of 2 problem areas. 1- check the ground from the engine to the firewall and the ground from the battery to the chassis. 2- when the problem occurs turn the key slightly backwards and see if the problem goes away. Often times if you have a number of keys on your key chain it causes excessive wear in the ignition switch by pulling down on it and it losing contact inside the switch.

You may think I'm crazy, but I'll almost guarantee it's your cam or crankshaft sensor. Don't ask me why it does this when they need replacing it just does. Good old Chrysler products.

Hi I have a Chrysler 200 2013 when turn on air or heat there's a loud clicking last for 20 seconds.sound coming from behind glove box.even if car isn't on this noise will still run what is it.? Another problem I have only at night when lights are on the dash lights radio .clock gear .light flicker from hi to low constantly. I think it's the handle for signs lights has a short.


I own a 03 Chrysler 300m and today I went out to my car and my headlights were flickering on and off like the alarm was going off. When I left work, I turned the car on just fine but the headlights were still flickering on and off. Now there's a loud grinding noise coming from the passenger side of the engine when I accelerate. Anybody know what this is!?,

3 out of 3 people think this is helpful.

Is the grinding noise present when sitting still and simply reving the engine? When you're driving and let the car coast in neutral is it still present or only under acceleration? Considering the two problems could be linked, I'd look at the alternator. However it's possible they are separate issues.
