When the air temp is only correct on one side of the dash, this is most commonly due to a faulty Air Temp Blend Door Actuator. This is a little motor that "turns the door" internal of the HVAC housing to switch between heat and A/C as commanded by the control panel. The front system shares the same system, so if it's cold on one side, more than likely there is no leak nor is the system in need of a charge. If one side is good, the other side should be good, but just not switching over to A/C. So, the Actuator is located behind the glove compartment, mounted to the HVAC housing. Inspect the electrical connector for any loose, broken or damaged wires. Remove the Actuator and turn the blend door by hand making sure there is no binding and that the door is actually turning. If there are any problems here, the housing will need to be removed, opened and the internal door repaired as needed. If everything checks ok here, replace the Actuator.
