Air conditioning not cooling and surges at high speed

It's impossible to tell without testing hands- on, but it does sound like a climate control issue causing air flow concerns inside the vehicle and perhaps temperature blending issues. When you hear the rushing noise and air flow concerns, it sounds like some kind of mode door concern in then dash. Naturally some testing performed by a trained technician will help diagnose the source of the problem. www.repairpal.com/repair-shops
