I turn on the air conditioning
in my car and I only get cool air coming out of the drivers side
vents. The passenger side vents have air coming out of them, but it just
feels like I have my vent on. My car does not have a system that
allows you to select different temperatures for both the passenger and
driver sides. 1997 LeSabre

The 2 vents on the drivers side have warm air blowing out. ... But a system that is 1/2 pound low will cause the passenger side vents to blow cool or cold air, and the drivers side to be less cool or even warm on this car. There is simply not enough freon capacity in the system to cool the air to the drivers side. https://www.justautorepair.com/buick/century/cool-passenger-warm-driver

Possible that the vent is blocked if you meant that the car is not cooling with the AC. If so check the flow of air on the vent , remove and clean the vent.
However if there is heat coming in to the passenger side then the engine room insulation can be open or there is a possible leak from the engine room that allows hot air to flow into the passenger side than the driver side.
I hope this was what you meant, if not clarify once again.
It sounds like the control motor switching from hot to cold is stuck halfway in between the two temp settings. You will have to take it down and replace it, it is mounted under dash passenger side near the blower motor.
Assumed your AC unit is OK, but uneven temperature distribution. Try to throw the heater on an off severtime. A sticky valve on the heater would cause similar problem.
Observe the RPM while parking your car. While the AC cut in cut out (or turn on an off). If it cause no load on the engine. The freon may be low or the compressor is bad. In this case only the intake side of the evaporator is cooler than the other side.
