I have a 96 Riviera that when the air conditioning is on it is only coming out cold on the passenger and back seats and on the drivers left vents and the center vents it comes out basically about 75 degrees. Any suggestions on what part it may need? :(

It sounds like you have a blend door malfunction. Somethime you have to replace the A/C controller. It also may be as simple as a vacuum hose under the dash.

Check for a blend door malfunction, a failed A/C controller, or a disconnected or leaking vacuum hose under the dash.
