air conditioner

AC just died on my 2019 Touring. Dealer is fixing under warrantee. Not certain of exact issue, but wondering if AC issues are common. Tried searching forum but no luck finding similar threads. Cheers, Mike

2007 RTL, in the blink of an eye, went from temperature control beauty to blazing hot. AC on - blows hot. Temperature control system off - blows hot. Auto on - blows hot. Dual - blows hot. The small metal chrome plates on the heat vent adjusters are hot to the touch. Sounds bad. Thoughts?

The A/C was working great today on first outing. When I returned to my truck the A/C did not come on. I tried shutting it off, switching from Auto mode, adjusting the temperature - nothing at all. Not air movement or any indication that any of my control changes were registered. I'm hoping...
