Most american cars force the defroster to blow cold air, this is not a problem, it does this by design.

The air ducts need to warm up ...much like adjusting the water for a shower.

For your 2nd question..it's just the nature of the beast.

Hope this helps you

No heat or ac controls on a 1997 suburban


Is the blower running? Is coolant hot in the heater core when you set controls to hot? Do you have a picture of which setup you have?

2004 CHEVY SUBURBAN FRONT A/C WORKS BUT THE REAR DOESN'T TURN ON


There is a blower motor control processor for the back blower - it takes input from the front control and the rear control and decides the fan speed. That processor could be faulty, or the blower motor, or a 30amp fuse in the engine compartment.
In the front system you have a controller and blend doors that direct air thru the heater core and evaporator. You would need to check the operation of those blend doors.

You are going to need to use a multimeter and have a professional test the relay voltages. This should probably only take an hour, make sure they have the proper electrical schematic for your vehicle year make and model.

1999 Suburban, A/C on warm air from front vents, cold air in rear


The car uses the same freon in the front as it does in the rear. If the rear a/c is working, you either have a plugged evaporator in the front unit, or perhaps a bad heater switch. Try switching the heater to hot and see if it blows even warmer air from the front vents. If so, the heater switch is working and then it sounds like a plugged evaporator or maybe a plugged orifice tube. That is a good place to start looking. Hope this helps.

It sounds like you have a blend air door stuck. This is in the housing of the heater a/c blower unit under the passenger side of the dash. There is a motor on the top of the housing that could possibly be stuck or on working.
