Matt,
Thedealer found the problem…. It was the compressor. Once they duplicated the problem, it was easy to see the low pressures. They’re replaced by the compressor and expansion valve now. Thought you might want to know. Good luck.
I took mine to the dealer yesterday Brent is a really good diesel tech. As of last night, he hasn’t duplicated the problem. I hope he does better today If he finds the problem, I’ll let you know. I’m still betting that it’s the BCM
If my truck has been parked for more than a day, it will take 10 plus miles for it to start working. Running down the highway the ac works fine, but if I pull into a parking place and idol, the ac stops cooling. Once you start driving again, it starts cooling.
