2015 Dodge Caravan Electrical problems

Air condtioner started to only work on the drivers side. Everywhere else was blowing out hot air.

Back passenger door lock is stuck in the locked position. Nothing will unlock it. Dangerous for the passengers in the back, they can't get out on that side.

While driving airbag light came on with interior lights flicking on/off while driving on every occasion for last 1-2 months. Also while driving would say right rear sliding door was open with lights on while driving. Air bag light has since gone off and came back on/off but interior lights remain on at times while driving. Sometimes rear sliding door sounds like it's trying to latch. Local garage unable to find anything wrong it. I believe there is a electrical shortage that started with airbags and from reading there is a takata recall on other vehicles causing a circuit shortage like this.

Original owner. Van was in use and most of the dash warning lights went on. Most electrical items (horn etc) not working short distance to home but the motor would not shut off. The van kept running even with the key removed. Started to overheat since the fan wasn't working. Called dealer, advised to remove negative battery cable. Motor shut off. Tried a restart to position for tow truck. Van restarted and functioned. Flatbedded to dealer where "tipm" was replaced under warranty. Invoice chcs398350 teterboro chrysler, nj owned-driven many cars/trucks never saw one that would not shut off.
