I HAVE A 2000 LINCOLN LS V-8, 130,000 MILES. I AM HAVING TROUBLE WITH THE AC, IT IS BLOWING HOT AIR EVEN AFTER I HAVE HAD R134 PUT IN TWICE. THE COMPRESSOR IS WORKING FINE AND CLUTCH KICKS ON AS WELL. I DON'T KNOW IF IT'S ELECTRICAL OR WHAT.

It's probably something that you're not going to figure out on your own either. Refrigeration is not a DIY type knowledge.

Feel the refrigerant lines. One should be warm and the other very cold with the ac running.
The LS has those dithering hot water control valves that liked to act up and stick open and burn you out of the car. The LS doesn't use blend air doors. The DATC modulates the valves near the radiator to control the heater.
Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.

It doesn't use a Blend door specifically but it does have a "Cold Air Bypass" door in addition to the dual solenoids for heater control..
COLD AIR BYPASS DOOR ACTUATOR
The cold air bypass door actuator is located on the evaporator core housing. During automatic operation the control module can position the door fully open so that some of the airflow will not pass through the heater core. This will provide for maximum cooling. The door is closed or partially closed during modes other than maximum cooling.
- The cold air bypass door actuator positions the cold air bypass door on command from the DATC module.
- Operation of the cold air bypass door actuator is the same as the air inlet door.
