The blower for the ac and the heat is not working at all.
The first thing i would check is the heater blower motor for power.If the blower motor has power then pull and wiggle on the blower motor resistors pigtail or connector but make sure the heater and fan motor and the ignition switch are turn on so you can here if the motor comes on. A lot of times these blower motor resistors get hot enough to melt the connector causing it to loose its connection.

Well had the same issue on my duel climate controll 04 2500HD but changing the heater control solved the different temp.The only other thing would be your mixer door motor.There are two,one for DR side is probibly stuck..As far as the blower motor.The resister should have taken care of that.Sounds like you may have another bad one.May want to take a volt meter to the resister plug in and run you different fan speed just to make sure that you get voltage to the different conecters.

First check the coolant level if the engine is hot check the reserve jug on the firewall--if cold before start up remove the radiator cap and check coolant level add as needed. If the thermostat has been removed it needs to re-installed. It is possible that the heater hose(s) is stopped up. After letting it run for a period of time both heater hoses should be hot to the touch if they aren't something is restricting the flow of coolant the system needs to be drained and flushed. I have also see some vehicles form an air lock in the coolant system causing the same thing. It then needs to be (burped). This can be checked/done by removing the radiator cap while the vehicle is idleing and watching the water level in the radiator squeeze the upper radiator hose to see if the water/coolant level rises in the radiator. When you release the hose you may need to add some coolant this forces out the air. Hope one of these things. These are some of the cheapest fixes and if they don't work/help then you need to start looking at the heat control selector.

I'm having the same problem right now. Although mine started a couple years ago. At first you had to slam a door, hit the dash, hit a bump,etc., and it would start blowing again. I replaced the fuse thinking it would fix it because I heard clicking from the fuse.(wasn't the problem) then figured out as long as I didn't turn it off, it would be fine the next time I drove the car. But if you turned heat/ac off, the next time I got in the car, I'd have to slam the door, etc. for it to work again. After the intial incident, it's been fine until now(again, 2 yrs. later). I have now order the blower motor from Chevy(everything for this car is *special order*) so you may want to start there. Good luck!
SOURCE: Heater/AC blower works on high only
Blower housing resistor fried up.You will have to replace whole blower assembly.
SOURCE: blower fan not working. AC still cooling. Not
Sure. But could also be fan switch or motor. Check with a test light to make sure where the voltage stops.
