Look about the drivers seat and you will see a small round grill, it is the interior temp sensor. This might be your problem.

SOURCE: 2004 escalade ac problem

I had the same problem. Took it to an AC guy and they told me it was going to cost $1,400 to replace all kinds of parts. I didn't get it done right away because I went on vacation. When I got back from vacation the air blows cold. It hasn't gone back to blowing hot since.

SOURCE: 2000 escalade rear air works fine. front does not

the rear airconditioning uses a thermal expansion valve to control the amount of refrigerant evaporating into the rear evaporator, the front does not it uses a fixed orifice which cannot compensate for anything. what usually happens is that the refrigerant level is low and the rear expansion valve "steals" all of the available refrigerant.
I would recommend having the system evacuated and recharged by weight first(definetly the cheapest way to go). twice i had to replace the txv for the rear a/c because it was stuck open(in the last 10 years! ... not very common). also ther could be a door in the hvac system that is not covering the heater core. american automobile manufacturers usually heat up the heater core at all times and block the airflow when they don't need it, but air always flows through the a/c evaporator assembly(if the a/c is'nt on it's not cold). and last the cooling fan for the a/c system,and the cooling system on the car, is coupled to the engine by a viscous coupling that could have worn out(very unlikely). if that were the case you should have adequite cooling at speed, but warn up at a stop(also symptom of low charge) i hope that this information helps usual leak sources on gm are the compressors.
good luck

SOURCE: Why is 2000 escalade rear a/c vents blowing warm

it may be low on freon or the rear air blend door motor is not working right, the first thing is to check the operation of the blend door, then the ac preasures, low / high sides.

Why do not have cold freon at evaporator coil on 2003 eacalade


not enough info does the front blow cold and just the back blows hot if so there is a mixing valve to let hot water come to the back so in the cold weather you can stay warm if the valve is bad it will let hot water to the back if the front is also warm you probably need a recharge and maybe a leak in the sys.

More than likely, you have a blend door actuator problem. Locate the faulty actuator under the dash, usually on the firewall, and replace.

Here is a TSB (Technical Service Bulletin) for your vehicle for loss of temp control.
File In Section: 01 - HVAC
Bulletin No.: 01-01-39-007
TECHNICAL
Subject:
Loss Of HVAC System Mode and/or Temperature Control 

(Reroute Wiring Harness)
Models
1999-2002 Chevrolet and GMC C/K Pickup Models (Silverado and Sierra) 1999-2002 Chevrolet and GMC C/K Utility Models (Avalanche, Suburban, Tahoe, Yukon, Yukon XL, Denali) 2001 GMC Sierra C3
2002 GMC Sierra Denali
2002 Cadillac Escalade, Escalade EXT
Some customers may comment that they cannot control the HVAC system modes and/or the temperature. These concerns may be intermittent.
Cause
There may be poor terminal contact and/or bent terminals in connectors C206 (RPO C68 automatic HVAC controls) or C296 (RPO C60 manual HVAC controls). Excessive tension on the wires due to the wiring harness being miss routed in the instrument panel carrier may cause these conditions.

If the warranty campaign is over i am sure they can or may have in the system on how to correct the problem.
Good luck and hope this helps, keep me posted if you need help on to the repair procedure.
