Problem cold in one vent warm or hot in the other

possibilities at the temp you are at is a little low on r134a,you can put in a can from any auto store and follow the directions on the can.The other is a simple stuck duovalve located up by the pass side firewall in the recess that holds the ecu.Looks like two little beer cans sitting side by side give them a firm tap on the sides with the handle of a screw driver,not to dent them just a good drum like tap.
After doing the above run the tests again and also check for errors again.
