dual temp climite control only blows cold no heat on pass side drivers side works fine hot or ac

 

low coolant

 

coolant is full in radiator and res how does one test or locate air duct switch for passenger side control or should I just start with change of dash control unit

 

do u have duel controls one for pass one for driver? Did u open up the radiator cap and look in there not just the over flow tank?
