an expansion valve is a common device in all type of cooling appliances. It works on a very basic principal. A compressor in the device compress the coolant in the machine, then it released from there it goes to expansion valve, in expansion valve the gas expand. Know if you would be having a basic knowledge about the conservation of energy then you you'd be knowing that energy is required for doing a work. So her work is done in expanding the compressed coolant in the expansion valve. So the energy required for this is obtained from the coolant itself which is hot on coming from the pipes after cooling the object it was made for. The heat of the coolant is used as energy source and gradually the temperature of the coolant drops down and become ready for sucking more heat.

The rear ac unit of your 2003 Tahoe does not blow cold the front works fine the line to the rear does not get cold like the line to the front?
I believe the rear Expansion Valve may need replaced. If it has failed the rear evaporator will not cool as the freon will not flow. These Tahoes have an orfice up front and an expansion valve in the rear (inside the rear HVAC unit under the passenger quarter trim). The coolant lines and the A/C lines have to be undone to remove the HVAC system from the vehicle to replace the Expansion Valve. It's about 650 at the dealer (or you can get the valve for under 100 from an auto parts store if you think you can do the job yourself).
