I would greatly appreciate any help in this matter. I have a 2005 300C and currently have 107,800 trouble free miles with one exception. The 25 amp accessory fuse keeps blowing. It started blowing once a month, then 3 times a week and now a new fuse will rarely last 5 minutes.
I have heard that the 300s were bad for blowing fuses and I was wondering if anyone has any information about this fuse, or basically if anyone else has run into this problem.
The fuse controls the center console lighting, trunk release, dome lights
and vanity mirror lights.
I took the car to the dealer and they said that they could not find a short anywhere and charged me $87.50 for the diagnostic. If the dealer can't find it then I don't know where else to go. It is getting really old to have to replace the fuse every time I need to pop the trunk and I don't want to have to drop the back seat and crawl in the trunk to pull the manual release all the time.
Welcome to the forums, MoparPat! Sorry to hear about the fuse situation. You are not the first one who has needed to pull down the rear seat and climb into the trunk in order to pull the trunk release, lol!
I basically know nothing about electrical shorts/blown fuses. However, I do remember one member sharing a very similiar incident. Turned out, the source of the blown fuse was being caused by a coin stuck in the ashtray plug. Apparentlhy, the fuse for the center console plug is somehow tied into the ashtray plug.
Hey, it's worth a look-see. I'm sure someone much smarter than me will come along and help you straighten this out.
Good luck! AND, congratulations on possibly having the highest mileage LX vehicle on this forum.
Thanks 300cDave and soundiceuk. I considered your ideas and I thought that I would first disconnect the battery for 15 minutes and then connect it again to clear the computer and see if that helps. If that does not work I will proceed with your ideas about flashing the computer and then to trace the wire circuits.
It makes sense to try the easiest things first. (laughing)
I went ahead and disconnected the battery for the 15 minutes about 10 days ago and the fuse has not blown again....yet. I have driven it 450 miles up to 108,250 and so far so good.
I thought that it would also be a good idea to disconnect the battery and reset the computer because I am running a Borla exhaust and a K&N filtercharger intake and maybe the computer will adjust to better accept these accessories and make an extra 1-2 horsepower. I would like to think that the car would run a solid 13.9 in the quartermile with these accessories.
I will update the forum if and when the fuse blows again and what the fix ended up being.
I have an 05 300C AWD. Last night I think I blew the same fuse that you are speaking of. Console lights, dome light, trunk release. I looked in the owners manual and none of those are listed in the fuse descriptions in either the front power distribution center or the rear. You mention a 25 amp fuse. My owners manual only lists three:
Memory Module/Door Locks
Power passenger seat.
I cannot find a blown fuse via visual either.
Where is the fuse in yor car? In the front or back power distribution and what location number?
I had the same problem when looking in the owner's manual. None of these lights are listed. I also could not visually see any blown fuses.
I went to the dealer and their service guy said that it was the #1 fuse in the trunk and they had to order it from Cleveland and it cost $11. It is a tower type fuse, not the 20 cent one. I ordered it and installed it and to my surprise and displeasure, this was not the right one. Back to the dealer service department again. This time a different service guy scans it and tells me correctly this time that it is in the FRONT Power Distribution Center and is in cavity #5.
After replacing it the next time I discovered that it is actually the only 25 amp fuse in the front power distribution center and the color is "Clear". The owner's manual has this fuse listed as "Headlamp Washer". Now why would they not list the interior lights in this description? Or the trunk release since there is no key lock on the trunk?
Good Luck, I think that you will find that this is the elusive fuse that you are looking for. Front fuse box, cavity #5, clear 25 amp.
I have a base 300 and having the same issue. There's only one 25amp fuse which i changed and it didn't work. Someone "PLEASE" give me some insight. Not having a trunk is ridiculous yet not having any interior lighting.
