Is the radiator fan still coming on ? Is the compressor running ?

vacuum line cracked or lose

blower motor is on the passenger side underneath the dash

Have you replaced the blower motor resistor? It's located behind the passenger-side in-dash glove box. That's what allows you to control the fan speed.

THE REASON THE BLOWER ONLY WORKA ON HIGH IS BECAUSE OF SOMETHING CALLED THE BLOWER MOTOR RESISTOR. THIS IS A BLOCK WITH ABOUT THREE DIFFERENT RESISTORS ON IT WHICH CONTROL THE AMOUNT OF VOLTAGE THAT REACHES THE BLOWER MOTOR THUS GIVING YOU YOUR DIFFERENT SPEEDS.
THIS BLOCK IS USUALLY LOACATED BEHIND THE GLOVE BOX AND IS BOLTED TO THE HEATER HOUSING.

P0740 Torque Converter Clutch Circuit Malfunction, it could be a sensor starting to go bad, have the code cleared and see if it happens again, have you ever had your transmission fluid replaced, (do not have it flushed) might want to do that as a Preventive Maintenance item.

A/C problem could be the A/C controls on the dash are not working properly, the doors inside the dash are not closing completely, letting warm blended air in on the driver's side.

It sounds like your fan motor is either bad or not connected to the power source due to a bad switch, or bad or disconncted wire(s.) This will require you to remove certain components of the dashboard. The center part of your dash will "pop out" if you pry under the edges very carefully. After it comes off, you will be able to access the fan motor switch.You can put a test light on the (+) positive lead to the switch to find out if power is getting to it. Also you can bring a lead wire to the fan MOTOR to see if it runs when powered. IF there is power to the motor and it still doersn't run, replace it. If it runs, replace the switch in the dash.

It needs an A/C discharge line I think I have done over 100 in those cars it is a big problem in those cars.

air blend door jammed, or you have lost vacumn to the diaphram that opens and closed that door.
