Good afternoon and welcome to JustAnswer!!My name is ***** ***** I have worked for a Chrysler-Dodge-Jeep dealership for 19 years and I will do my best to help. I work part-time here on JustAnswer to help you and other repair their own vehicles, and I get credited by your ratings.. So before leaving the site make sure and leave me a rating. You can still reply to me as many times as needed, even after the rating.. I will need for you to be my hands and eyes since I'm not there, and to be honest with today's electronics a scantool may very well be needed to retrieve the codes or to monitor data to see what's going on... What codes are in the BCM and HVAC control modules? If you don't know you will need a scantool to retrieve the codes, once you have them post them here so I can tell you how to fix it. I have saw quite a few sun sensors cause issues such as yours but I won't know for sure until you tell me what codes you have.. Talk soon,Brad

A OBDII code reader will not retrieve HVAC and BCM codes, you will need a scantool.. Post the codes when you get them...
