As snowbird said, it's most likely your passenger climate control system. Could be a short in a wire or a burnt acuator that moves the passenger door open and close. If you don't have the money or time to troubleshoot the problem you can pull down the glovebox and you'll see a metal rod about 8 inches long connected to the acuator. If you pop it off by the white connector, you can move it to full hot or cold. If it was the heater core it wouldn't matter where the air is comming out, it'd be the same temp.
It'll take you 5 minutes tops to simply check it by moving that door.

Hello,I work on these cars and have issues w/ this in the past.The Buick uses the same evap core as the cadillacs and are considered a (split design),and are true dual hvac system.That being said I have found a slighty low ac fren charge can and dose cause this condition.If the ac has been charged then the issue can be a blend door actuator.This can be found behind the glove box (small black box w/ 4 or 5 wires going into it)held in place w/ 2 or 3 ,5.5mm screws. try to have the ac recharged first and see what happens. Have a great day! RAY
