Looking for help with my Grand Cherokee

Bought a used 2014 Jeep Grand Cherokee last year. Really no issues til lately. Little things have been popping up. The climate control inlay will occasionally loose power and come back on after a little while. I pulled it off the dash and checked the connection and it was solid. So then started having things like windshield wipers turning on and off sporadically. Now the battery low charge light is on constantly. Alternator was just replaced by dealership and I went ahead and bought a new battery since th one it came with was kind of old. So Brand new $200 battery in and same thing. Checked the battery with OBD code reader and all values for not running, startup, and running are good. Not sure if anyone else has had this problem but it's irritating and I am just waiting to see what will act up next. It's becoming dysfunctional. Any help is appreciated. Thanks
