With the ac on, the passenger side blows cold and the driver side blows hot. Have tried to adjust all dash controls, but no help.

Possibly a failed temp actuator, or one that has overtraveled its limits and defaulted. Have the system scanned for trouble codes, it should have code(s) that relate to the problem.
