The air conditioner on my work car gets cool but not cold , I added oil charge and freon but it dont get as cool now as it did before . The farther I drive the better it works. I'm thinking the problem is the filter in the line is dirty . Where is it located on a 92 lesabre with a 3.8 ?
What you are referencing is probably the orifice tube + a screen.
There are many things that can change the air temperature inside the car.
1. Inside AC/HEATER duct under the dash, the temperature door can be open a bit and let the warm air mix with cold air temperature.
2.The purpose of the orifice tube, that is between the high pressure and low-pressure tube you can feel with your hands the cold and warm tube
The screen is blocking particles of metal from A/C compressor if the compressor is defect.
high-pressure side is HOT
low-pressure side is COLD
3. A/C compressor clutch could slip more than it should. The air gap has too much clearance.
The location of the orifice tube is :
New Orifice Tube EX 5151C 302272679 S10 Trailblazer Blazer DeVille eBay
To show you an example withdrawing and principle of A/C system and where to look for your question.
Hope it helps.

Yes the system can be full of freon and yet not work, the pressure switch could faulty, the expansion valve too could be faulty, he drier receiver too.
On switching 'on' the AC , is the AC compressor workingor rather does it engage?
The AC compressor clutch too could be not functioning.
I guess you have to go step by step to check first if the AC compressor does rotate on switching 'on' the AC.

Vent door between the two sides isn't opening or the flex hose going between the two is off.
SOURCE: air conditioner blow warm air after freeon
you could have a leak in the ac system which would be why you had to add freon. take it to a repair shop and ask them to check fo rleaks because adding more freon wont fix your issue if there is a leak.
SOURCE: Air conditioner not blowing cold air-
