I’m having some trouble identifying the cause of my intermittent AC issues. I have a 2018 1500 Big Horn and I’ve been driving it about 100 miles a day and as the weather warmed up I’ve been turning on the AC. It was working fine for the first few weeks and started to now blow very cold for the first 30 minutes of my drive. The last 20 minutes it would start blowing cold again. As the weeks went on it was weaker and weaker. This past weekend I took it on a 400 mile road trip and I would have to turn it on and let it rest for a minute when it was blowing warm. I’d turn it back on and it was slightly cooler. During the drive there was a little noise coming from the vents and some little white flakes came out of the vents for a second. My friend said he thought it may have been ice since we couldn’t find it anywhere inside and the floor mat has a few water drops on it. It has not happened again since. Haven’t had time to take it in to see if it is just running low on Freon and I have a small leak or if there is a more serious issue. I had checked my cabin air filter and that was clean. The ice coming out of the vents has me a little concerned but at this point I’m waiting to take it in to get looked at until I can find something on forums somewhat relating to this. Any thoughts or suggestions would be appreciated.
