Answers :

I remember my 94 yukon had a little flap by the heater air box under the dash that was motorized. This went out on me. It is possible the diversion flap on yours, like most cars, is vaccum powered. So if thats the case it is either a vaccum leak, or a bad thermostatic control unit. Chevys have been know for bad controls in these vehivcles. The fan speed switch is a common one to go because it is used most often.
