#1 of 80 300M Lights blink randomly
Jul 31, 2007 (5:56 pm)
The lights up over the windshield have started blinking whenever they feel like it. They will blink a few times and then stop. There may be other lights blinking, too, but it only has happened when the car is moving so far and i can't tell.
I would expect that these lights are controlled in a number of ways. Unlocking the door, nights when getting out of the car, turned on by pressing the light, others.
Any idea what causes this or how to fix it? Are the lights controlled by the car computer or in some other way?
I have a 2000 300M mileage in the 70,000.

Scroll the dimmer wheel for the interior lights completely up and completely down a few times, and turn the light switch from Auto to all the way on and back a few times. That should remedy it. If not, remove the whole switch and unplug and plug it 3 times (actual documented fix for this .)
#3 of 80 Chrysler 300M electrical problems
Aug 03, 2007 (8:41 pm)
I have a 1999 Chrysler 300M. It has 158,000 miles. I got in it and turned the key and that's when the problem started. I will list the problems in order to keep the message as short as possible. I could not arm the alarm, doors will not lock by using the power switches on the doors,the rear windows will not go up or down and I can only let the front passenger window up, not down with the driver switch, the a/c and compass comes on at 75 degrees and there is no electricity going to the a/c compressor.Electricity was applied to the a/c compressor and it worked fine. The interior lights will not come on, the power mirrors have no power, the radio has no power, and the turn signals will not come on. The funniest of the problem is when I turn the key to start the car the horn blows! Is this a sign that the body controller module has gone bad? I have enjoyed this car and I do not plan on getting rid of it. Any help or advice will be greatly appriciated!!
Thanks A Lot

Thank you. Scrolling the dimmer switch did the job. Haven't had a problem since i did that.

Hey, coldnight300 I have the same problem you have with your 300m. My 300M has about the same milage as your's. The only difference is that my windows and turn signals work fine. I also need some help or advise. Have you checked the fuse box. I checked mine and it was blown out, but when I tried putting in a new one it got blown as soon as it made contact. See id your fuse is blown out, if it is try to put a new one and see if you have more luck than I did. That's the only advise that I can give you at this time. If you tried something diffent can you let me know because I also dont' want to get rid of my ride.

My 99 300M , 127,000 just did this very thing tonight on the way home from work. I thought to scroll the dimmer switch, up and down as suggested, and it didnt do it again on the ride home....lets see about tomorrow.
Issues I've had:
Currently passenger rear window wont go down.
Passenger heated seat works-sometimes-??
oh yeah and the car doors attract door dings like crazy???

Before I got my '99 300M I had a '93 Concorde. Shortly after I bought it, used, I started having electrical problems. All the interior lights would quit, the dash lights, AC, turn signals, radio, power windows and seats would stop working. They might work fine later that day then quit again. I found in the service manual I bought for it that all these items were grounded to the chassis by one bolt under the console. It was hanging by a few threads and sometimes a bump would make it loose. I tightened the bolt and never had another electrical problem. I can't tell if the same thing is happening on your car but a bad ground can louse up a lot of things!

Hey aj86. Thanks for the advice.I checked all of the fuses and they were fine. The electrical repair mechanic I talked to (not the dealer, another auto repair company) told me right away that the body control module (BCM) needed to be replaced. He said I have to take it to the dealer to get it repaired. The part at the dealer costs $480.00. The service department is going to charge $150.00 to install it and this includes programming the body control module. I now have to order it. They told me it will take 3 to 5 days before it gets to them. I will keep you updated.

Hey quietflyer. Thanks for your advice. The ground wires were ok. I had one wire hanging behind the back tire on the driver side. It was connected to the muffler. I still had the same problem though. The electrical repair mechanic said the body control module (BCM) needs to be replaced. I will keep you updated. Thanks again!
