Asked by for the 2004 Chrysler Pacifica
Not really an answer, I just discovered the same problem with my 2004 pacifica. Dealer says he doesn't hear of this problem often. Since I am due for 100k maint. will get back to this after the diagnosis. I am not optimistic, as this dealer ( the only one in my area) is not too user friendly :( They wanted me to repeat services I had done recently (?). I had to remind them I do not always bring my car there for standard service, I use a shop in town that is more reasonable and friendly. I took my car there today, but other than the fuse check, they said it would be best for the dealer to check it out. Will let you know what I find out.
Have either one of you figured out what the problem was? I am having the same exact thing happening with my car now. Thanks.
This just happen to me last night HELP PLEASE
Same thing happened to my 07 Chrysler Pacifica
