Long time lurker here. 2017 1500 limited, I am having an intermittent problem with my AC. freon pressures are good, E fan works, and I have replaced the low pressure sensor. It works great at all speeds on the road and sitting in traffic. And, then for some reason , the fan slows down and it blows warm air and then cold, then warm then cold etc. at all speeds and idle. Idle is when its the worst. I am thinking it may be the HVAC module. What is your opinion? Went to the dealer to let them look at it, had an appointment today at 0800, then they tell me it will be a week before they can get to it because it has to go into the main line for diag. I was more than a little irritated.
Thanks
