    Make sure the 2 heater hoses are hot to the touch the same as the upper hose at operating temp, 180 - 200deg. If those are good, possible temp/blend door actuator, is it dual air control.

    not sure about dual air control,it does just have 2 levers one for driver and one for passenger. they don't have actual temperature settings. just little slides that go from blue(cold) to hot(red) It almost seems like the a/c is "stuck" on. by the way thanks for the info

    That is a dual control system, and usually if the actuator was bad it would effect one side or another, not usually both at the same time. Check your coolant level, it has to be full, and your heater hoses.
