Cold air no heat !
 

I have 2003 Camry and it blows cold air when heat is turned on ! it has the digital controls . The temp gage reads normal no overheating , which makes me think its not switching over to heat with the door under the dash or something .. any help would be very appreciated...

could be actuator on the directional flaps

not sure how a 2003 internal radiator works with digital controls

picture is of a 2005 camry set up

and the 2003 heater -AC door actuator
