Car interior and wipers malfunctioning

Today's cars have tons and tons of electrical stuff, which requires good, clean, strong, cable connections. Anything less will cause electrical systems to act weird. So try cleaning the battery terminals and cables and make sure that they are super tight (tight enough that you cannot move the connectors by hand).

Here's a guide on cleaning the terminals and cables: https://www.2carpros.com/articles/everything-goes-dead-when-engine-is-cranked

Sounds like a case of "Totally Integrated Power Module" (aka "smart fuse box") failure. Very common on that vintage Chrysler. It is a fuse box that they decided to add a computer to as well as integrating 99% of the electrical functions and controls into.
When they start to fail you think your vehicle is possessed.

Unfortunately they are not a cheap item to change and most require a pro level scan tool to fully diagnose and replace them. The actual mechanical replacement is easy, they snap out of the bracket and unplug, reverse that to install the new one. But then they need to be initialized to your vehicle, That means you use the scan tool to enter the VIN number and tell the TIPM what vehicle it is in and what options it has.

If you want to read more about this there are a lot of articles online, just google Chrysler bad TIPM.

Well I learned something new today, thanks again to Steve. But I still think it is worth taking a look at the cables and terminals. Cannot hurt and there is a small chance it could help.

Sorry for jumping in there Heyman. Just trying to assist.

Cleaning never hurts when it comes to electrical problems. It is downright amazing how many "my battery is dead" calls are repaired by cleaning and tightening the terminals !

Nice work team!
