It should be located after the blower in the ducts.

I have a 2002 Lincoln LS and the air conditioning works up until it gets 95 degrees outside then it stops working and just blows hot air. Any suggestions on why this happens?

that car has a intake manifold leak you have to check your car in the morning look in the plastic fill reservoir and it should be you to the cold line that is the line on top the hot line is the lower one make sure it is up to the cold ligne stick something in there if you can not see it

On the central console is the A/C module. Inside A/C module are driver's side & passenger's side air flaps for mixing hot & cold air and directed air flows towards driver's side & passenger's side according to driver commands. The passenger's side flap for mixing hot & cold air according to driver commands is bad. Flaps are actuated by electrical step by step motors. Could be damaged the flap actuator (motor), the flap mechanism (blocked in "HOT" air position), and / or electrical supply wires. You must access the passenger's side flap for mixing hot & cold air, and see what happens when you command cold air to the driver's side: flap mechanism, flap actuator, supply wires, ... Repair & replace bad pieces and test the A/C system.

It is likely that the Coolant Control Valve on your car has failed. This valve is located on the passenger side of the radiator fan shroud near the bottom and has 3 coolant hoses connected to it. This valve regulates interior duct temp by changing the amount of water flow to the heater system.

You need a scanner to diagnose,not a code reader.

The DATC Module ( Dual Automatic Temperature Control Module) is a possible

If your LS is blowing hot air on one side of the dash and cold on the other the problem most likely is the Dual Coolant Control Valve. The DCCV is used to control cabin temperature. This valve is mounted down low on the passenger side of the radiator fan shroud, and has 3 coolant hoses connected to it. This valve if found to be faulty will need to be replaced to correct the condition.

What have done at the dealer before and works you should have bills should be an explanation.

The problem is most likely a bad dual climate control valve. This component is located on the right side near the radiator under the hood. It will have several coolant hoses hooked to it and 2 silver cylinders protruding from it. You can clamp off the heater hoses at the heater core and see if both sides cool then and this will tell you that the valve is letting coolant thru when it shouldn't be.

This will narrow it down to either the valve or the control head inside the car,or wiring in between them. The only way to narrow it down further is if you have a scan tool that could access the climate control data. Have seen several of these valves cause this concern and have only seen one control head cause it.
