This weekend, something weird happened with the dash A/C on our 2002 Dodge Roadtrek 190. The A/C was blowing ice cold with no problems, and in fact my wife noticed how well it was blowing cold. Then about 10 minutes after she said that, it started blowing not cold air. Felt like vent air. I stopped and opened the hood and took a look at the a/c compressor to see what it was doing. It would come on for just a second and then kick off. We parked overnight and the next day I checked the refrigerant level thinking it might be LOW on refrigerant 134a. It was not low on refrigerant. Drove the next 3 hours without any problem at all, a/c blowing ice cold as usual. I'm thinking a relay, or a faulty clutch, or expansion valve? I don't know what went wrong.

possibly iced up in the evaporator,blocking air flow.

I had a similar problem during a heat wave earlier this summer. AC ran fine, then stopped. After getting off the highway and driving through a city, the AC started working again. I don't know what happened, but, I suspect it was the blower motor (no air came through the vents). I was going to replace it, but, since I haven't had the problem since I'm going to hope it was one of those one time weird things that sometimes happens. If you do find out your problem, please let us know. Good luck.

keep the fan turned up and adjust the cold setting down (less cold) to maintain comfort with more volume of air versus icy cold and low air flow.

I had a 96 190P on a Dodge and the AC did this ever now and then. I would just turn it off going down the road for a minute or two and it cleared and was fine. Used it that way for years. Just freezing up a bit.
