The AC only blows cold on the driver's side. The pushing of buttons to do a reset proved no help.

Yep, you can try a HVAC reboot but most of the time the blend door actuator on the passengers side will be bad and needs replacement. Here is a guide to help you reset the system and the location of the actuator as well.
