Hi Scotty! I have a 2000 Chrysler Town and Country with 165,431 miles, auto trans, and 3.3L flex fuel engine. I've never used Flex fuel. Everything with the vehicle was fine until early September, 2020. At that time my daughter began to use the van as a storage shed for her car parts as she made modifications on her Subaru WRX in the driveway next to the van. As such, she left the side doors open and the dome light ran the battery down.
At the end of September, the vehicle's annual Texas safety inspection was due so when I attempted to go to the shop the van would not start, dead battery. I threw a charger on the car for a couple of hours but still it would not start.
I removed the battery connections, cleaned the battery posts and cable ends, reconnected them, charged the battery some more and the van started right up. I happily drove to the shop for my inspection. That's when my troubles began.
The technician came out during his inspection of the van and asked if I had recently disconnected my battery. He said he could not complete the inspection because the ECM had four "not ready" codes due to my disconnection of the battery. He told me to drive the van about 150 to 200 miles and it should reset. I have driven the van for 1100 miles and the codes have still not reset.
Worse, and my true question, is the "Key-in Ignition" chime, the Odometer and Transmission gear indicator lights on the dash, and the headlights have all gone haywire. The "Key-in Ignition" chime sounds off every time I open the door, even when the keys are in my pocket. The odometer and transmission indicator lights randomly flash on and off, and the headlights won't turn off. In fact, the headlights won't turn off even with the headlight switch removed and sitting on my workbench! Also, the lights and the chime will both turn on and off at random, as though someone were rapidly flipping an on-off switch. I can hear the relays under the dash and under the hood click each time the lights and chime turn on and off. The only way to stop this behavior is to disconnect the battery, or remove the Low beam, Hi-beam, and Parking Light relays under the hood. I choose to remove the relays.
Any idea what could be causing all of this and what I can do to fix it?
Thank you for your help.
my educated guess would be that she left those doors open water got in and destroyed the electronic system when computer modules and stuff get wet all bets are off it could cost a fortune to the guy try to get that thing legally inspected I know guys in Texas that inspected them on the fly there's always guys like that around you can find
