Had car in to dealership twice. Problem doesn't occur while there. Cools fine. Every now & then it starts blowing hot air out of one side while blowing cold out of other side (dual climatrol). Sometimes it will be the right side & sometimes the left. Temperature setting both @ 70. Saw that there have been other similar complaints list on the Internet, (3) but no solutions found. Always happens on a hot, 80+ day.
