1997 Cadillac Deville hot and cold

Do you have duel climate control? One for driver and one for passenger

Yes, it does have an adjustment knob on the pass. Door console, but it still blows cold no matter where that dial is set. Driver side still hot no matter where pass. Dial is set

Ck the freon level, you need a guage for AC. It runs about 28 to 30 psi on the guage, if its lower than that its low and needs a recharge, if its higher its got problems like a blockage, probally the orfice tube

you can also pull the codes for me to see if there is any AC codes in it

push off and warmer on the heater controls at the same time, with the key in the on position, look in the message center on the Insterment panel for the codes and post them here

Thank You all for your input, I found the blend door, or zone control actuator whichever you call it was stuck. I gave it a little twist with a pliers, and now it works fine. Yeah kids will be happier. Thank You for your time.
