I am just curious, does everyone in this forum with this issue have a 12 inch display or the 8.4?
I am having the issue with 8.4 and I don't have dual climate either. The driver side is not as cold as passenger and at times it blows cool air. Truck is at the dealer right now for the 2nd time to try and address the issue.
1st time they said that they flashed and updated the display (I don't understand why because I do not have the option to control my AC from the display). I went to the dealer and picked it up drove a block and turned around and dropped it off again (My Service Advisor is a GREAT guy BTW, I don't want this to reflect negatively on him) and I showed my SA the difference in the temp. He went to go get a mechanic but the mechanic just told him its probably low on Freon.
Now they said they are going to flush the freon and refill but based on this thread (which I mentioned to my SA) I don't believe its going to fix the issue.
Honestly I am a little frustrated and disappointed with FCA, and to make matters worse I had to purchase a rental package for $175 because Dodge will not give me a loaner to drive while they are trying to fix an issue that is from the Manufacturer. I understand not giving a loaner for an oil change or service but if your truck has an issue and I have to drop it off I cant believe that a loaner isn't provided. Maybe I'm spoiled because I came from a Lexus but that seems ridiculous to me.
I will not stop taking it in until this is fixed correctly and I refuse to do the temp fix so that later on they use it as an excuse to void my warranty. I didn't pay 45K for a truck to have AC issues when it doesn't even have 700 miles on it yet and be forced to do a rig for it to work as it should!
Im sorry for the rant guys, I'm just a little frustrated. I'm just glad I leased it and didn't buy it!
