I have a 2000 cadilac escalade.. I just had the compressor. dryer orfice tube and hoses replaced. the system was pulled down and held over night.. my problem is the systems works fine sometimes,, goe

These trucks are known for temperature control door actuator failures. Does it have dual zone climate control? Is the temperature the same from left to right. Does the rear get warmer too? If it has automatic temperature control (setting to a specific temperature instead of just turning a knob from blue to red) it will only blow as cold as you set it. Intermittent problems can be difficult to pinpoint without seeing the truck.

Both AC and Heat blow the same air.

Sounds like a flow flap or vacuum control head issue. The system uses 1 blower motor and one fan resistor. Both systems are intergrated to produce a BLENDED temperature. This means that to raise A/C temps originating at say 20 degrees to come out of the ducts at 45 degrees for cooling you need airflow through the heater core WHILE the A/C is on.
This is done with a blender flap. Hot air that is potentially matching the water thermostat (165 degrees) is expelled to blend with the 20 degree air to raise the discharge temperature to 45 degrees and up.
In winter, the A/C is engaged by design to keep the compressor lubed with oil. Usually this happens in Defroster mode, but through either Design or defect, may occur in heat position.
Now some of the Digital Climate control units have a Diagnostic sequence you can activate with certain button pushing combinations. Research Your Model, Year and then Climate Control Diagnostics on the internet. The sequence is something Dealers know about.
This Diagnostics would identify a malfunctioning Flap valve actuator.
I recommend people to visit a Salvage yard which allows you to dismantle a car yourself and see how the car is built.
Hope this helps and makes sense to you.

The ac in my 1998 Lincoln Towncar is bolowing very hot air. The evapoarator and lines under the hood are cold and there is condensation present on them. The temperature controls switch seems to be working...

Your lines are cooling but you still have heat coming out. Check you heater lines going to the firewall. On one of them is a valve most likely with a vacum line attached. You should be able to close that valve manually and see if that resolves the issue. If it does you have two options. 1, Replace the valve or trace down the vacum line and see if you can repair it. 2, You can disconnect both heater lines and connect them together basically removing the heater from the equation. Another problem could be the AC coil not working as it should due to a blockage of some type but this is unlikely since you lines are cooling.

Heat will not shut off when air conditioning is on. When temperature is set to 60 degrees, outlet temp is 105 degrees.

are you sure your ac is working at all. a old school solution would be to put a cutoff going to the heater core in the water hose.

2004 Chevy Silverado AC is blowing warm air on passenger side.

You have dual zones that are controlled by temperature actuators the passenger side has lost its memory or has gone bad you can put it in self programming by disconnecting the battery for ten minutes then hook it back up start the truck turn the temperature control on but do not touch any other controls let it go thru the self programming for about 6 to 7 minutes then select your temperature you want if it still does not work properly you may have a bad actuator or a bad connection at the actuator
