Chrysler 300/300C/300C SRT-8 Electrical/Lighting

    I have a 2005 Chrysler 300 limited. I recently took it to a dealer to have my computer reset because of flickering lights. (There is a TSB about this) However, when I picked up my car my cruise control no longer works. Any body else had this problem?

    Our 2005 Chrysler 300 has had the battery replaced twice under warranty. Dealer advised dead cell each time. 13 Jan 09, it died again and I replaced the battery with a larger, stronger after market battery for half the price. The dealer wanted $270.00 for a new battery and $80.00 to install it. 15 Mar 09 after sitting for five days I now have a dead battery again. Has anyone found what is wrong with these vehicle to cause so many dead batteries?

    I have my car towed in 6 time in the last 4 months. The dealer has replaced the battery 5 times and one alternator. If the car sits for more than 48 hours it will not start . Two dealers have run every test they know of and cannot find the problem. Anyone have any suggestions?

    You have a short somewhere. The dealer is not the best place to have this looked at. There are auto electric shops that are more experienced than the techs at the dealer in finding this.
  • Simple question - Have an 07 300C - Have had a large moth and a few flies get into the rear center brake light receptacle, and quietly pass away! In order to give them a decent burial I need to get them out of there, but no one, not even the dealer, seems to have a clue about getting inside there. Are the insects smarter than us? Need some help!!!
  • It is very unlikely that you got 2 bad batteries. You probably have what is called a "parasitic" load. That means something is drawing the power from the battery AFTER you turn off everything and leave the car. You can test the car yourself for a parasitic load with a simple 12 volt test light.

    Disconnect the NEGATIVE battery cable and hook up a test light BETWEEN the cable you just took off and the battery post. You are going to need a helper to do this test. Attach the test light clip to the battery cable you just disconnected and the other end to the battery post. This puts the battery back in service but only for testing purposes.
    If the test light comes on and it most likely will, then you have a parasitic load which confirms why the battery is going dead.

    Now, while the test light is ON, start removing fuses one at a time until the light goes off. Also, remove any relays if the problem isn't found with the fuses. When the light goes OFF, that is the circuit that is killing the battery because it is still drawing power. Have that circuit checked if you don't know how.

    If all testing fails to turn offf the test light, the Alternator could be the problem. If you know how to get to the Alternator, disconnect the large power wire from the back side. (This is a live wire when the battery cables are both attached). This large power wire is usually held onto the Alternator by a #10 Metric nut. Disconnect the wire and if the light goes out, you need an Alternator. Good luck!

    i recently purchased a 2006 300. The radio, screen, and navi all work perfectly, but when i try and put in a cd i'll push the load button then the disc number and all that comes up on the screen is "Disc Error" when i haven't even put a cd in the player yet. Has anyone had this problem or maybe know of a solution?

    Had the same thing happen to me just yesterday. It seems like a mechanical problem. I gave mine a good whack (and I mean good) and it loads, ejects and plays CDs again.
  • Did you ever find out the problem, I have an 05 Chrysler 300 with electrical problems that will not stay charged for more than an hour or two, and none of my dash lights work, and sunroof has a short in it to.
  • While under warranty, the dealer could not duplicate the problem, thus could not find a resolution. The battery seems to hold a charge now, as long as the car is driven every few days or so. I took the car into another Chrysler dealer after a two week vacation and coming home to a dead battery. The battery was recharged before I went to the dealer and low and behold, they COULD replicate the problem...noting that the battery continued to have a drain when the key was off and removed from the vehicle. Unfortunately, the dealer informed me that they would need to remove the panel & dash to investigate further and it could cost upwards of $1500 to figure out which component was pulling from the battery and to repair. ...I now carry jumper cables everywhere I go.
  • I have a 2008 Chrysler 300. I purchased it used about 2 months ago. I recently had a problem with my wipers not shutting off. Even with the car off, the wipers will run. I have had to remove the fuse to shut them off. Since we have experienced the turn signals not working, intermittently as well as the radio. Has anyone else had this problem? Is it a problem with the computer?
  • How do I repair the dash light for the heater /ac control?

    2005 300C with dead speedometer. Suddenly my 300 C's speedometer went dead while driving. An ideas? 17,000 miles clocked on odometer which is working..
  • Hi, I have a 2006 Chrsler 300. When I turn the cruise "ON" the dash screen says "Cruise ON" but when I try to st the cruise nothing happens. Any idea what my problem may be? Thanks!
  • "Cruise On" means the cruise control is activated. When you reach your desired speed, you have to flick the lever down to "set" the cruise control. Check your manual if you have one- if not, write back and we'll get it straightened out.
  • Did you ever find out the problem? I have the same trouble with my 05 Chrysler 300. I have to charge my battery every time I leave my car off for over an hour. Also when it is charged, nothing works, including everything on the dashboard, my headlights stay on at all times while running, and they sometimes flicker.
  • Thank you for the information, Im going to take my car to an auto electrician & see what they say. I will let you know if they find anything out okay.

    I had a problem with my 300C. When it reached 30,000 miles all of the dash gauges would turn off for about 3 seconds. Enough to scare me. For the next 20,000 miles I would take it back to the dealer every month, and maybe twice a month. The entire car started turning off, and I would have to put in neuteral and start it back up. As you know could not duplicate. Finally the service man said he called the extented warranty company, and they told him to check the battery. The battery was running on 275 amps, and was suppose to be at 730. The warranty company told him they had that problem before. New battery and have had no problem for 2 months now. I drive it every day.

    Any luck with the electrician? My car is back at the dealer. Waiting to verify the problem. I'm wondering if the battery amp issue posted recently is our problem.
  • if u havent got your cruise fix try checking the brake switch on the actual pedal it could be bad not not letting u set the cruise
  • My 300c is doing the same. Did your dealer hook it up to the computer for troublehooting? Our dealer told us that they have traced the problem to the wiring harness but no a specific unit. I'd be interested to compare the code reading on yours to ours. Thanks.
  • pnelson1pnelson1 Posts: 6
    Interesting. The dealer had my car for over a month and found no problems. Did they say what needed to be done with the wiring harness to fix the problem?
  • They can't pin it down to the exact component. It is a stored code F202. Until they can check it when it is active they won't touch it. I've been to Chrysler for relief, they told me until the dealer can pin point the problem, I'm out of luck. So, will have to wait until the dash is going wacko and bring it in. As, you know, you can't predict when it will happen or where. If you turn the ignition off, the codes go to stored and not in an active mode. They want to fix it but can't find the cause. I'll keep you posted. We're taking it on a road trip this weekend, so will see what happens.
  • sort of an electrical question: on the Mopar RAK OEM radio (am/fm/6-disc/cassette) I keep reading that it has an audio-in jack, for among other things, connecting an mp3 player.

    I looked at numerous pics of this head-unit and don't see any such input.

    Can someone please confirm for me whether or not this is true? Tell me where this input is located?

    Thanks. Thinking about purchasing a 2006 300 Limited AWD...

    I have been experiencing problems with the power outlets. Besides the normal fuses blowing, they seem to not be usable although they do light the indicators on cell phone cords, the phones do not charge. The dash around the heat/AC seems to be getting very hot when this problem occurs.

    FYI: I just had my EGR valve replaced at 40K miles after the "Service Engine Soon" light came on and the error code read out as the EGR valve. This is a 2005 300 Limited and about 3 minutes after I pulled away from the dealership, the "Service Engine Soon" light came back on again! I also noticed that night that the crusie control was all goofed up. It would come on (light lit in the wand) but then go off as soon as you tried to "set" it. After that it would not come back on for a few minutes. Rather than going back to the dealer, I decided to try on ald trick I learned years ago. I disconnected the battery cables and let the car sit for 20 minutes, then I hooked them back up. Two days later - no "Service Engine Soon" lighrt and the crusie is fully operational.

    This is just an FYI for anyone that may have similar issues in the future.

    I have an '06 300 Touring that doe the same thing. Activation of the left turn signal shuts off the left running light. Did you find a fix for it?
  • I have a 2006 300c. The battery dies every few days if the car is not driven. Also, rear windows work intermittently. Dealer stumped. Went to an independant and they tested for parasitic load with no luck. Anyone have any solutions/suggestions?
  • ivanbroivanbro Posts: 4
    I would think they checked this, but could it be a bad alternator?
