Need to check your coolant level under the hood. If it is good suspect water pump.

SOURCE: OMGosh...denali blows out hot air on driver side vents

You can do on of two things to see if it will reset the hvac system. Remove the negative battery cable wait two minutes then reconnect. This may reset the hvac. If not you can turn your switch on, but don't start it. Pull the shift lever down to 1st gear tilt the steering wheel all the way down. Now start pulling toward you with the trim on the dash to remove the trim. When it is removed, you can remove the Hvac controller. Once you remove it disonnect the wires wait two minutes and reinstall. This should get you cooling.
