That sounds like the Blend Door Actulator has decided to go loopy. I heard of people turning it to hot and getting cold, Normally when this bit goes it makes a click click noise

My 2002 gmc serra has a issue with the ac and heater the lights turn on but no air I hit a bump and it will turn on for a second but it stop blowing air cold or hot what could it be....


the blower motor resistor relay are bad about shorting out and melting the connector causing a loose connection and when you hit it or a bump it'll make connection and work. look under the passenger side dash and you'll see two wires coming from the blower motor. trace those two wires to a little black box with somemore wires pluged into it and try to unplug the other connector that has about five wires coming from it. turn your key on and your a/c with the blower speed set on high, try moving those five wires if the fan blows and quits, then this is the problem. you'll have to replace the resistor and the wire connector.

The AC blows on #4 fan setting but doesn't blow at all on 1-3


That is the blower resistor. 4 is wide open, so, no resistance. I had 4 of them put into my truck. The wires were burnt and shorted the others until the problem was found. Check the plug if you do this yourself.
