hey everyone.....
i replaced my heater core and finally got that working but when i turn it on to the vent control the little doors that control where the air is going is not working... it kinda works for heat and defrost... the heater core is working... is my hvac control dash bad..... i was think it was because i took it apart and when i press on the thing that controls the door openings, it will close but if i take my finger off it will not work... so what do you guys think... could it be a bad hvac... im pretty sure thats what it is.... oh and if it helps i deleted my ac over a year ago....

 

The valve with all the vacuam lines hooked to it is all you need to replace not the whole a/c heater controls

 

thanks man... thats what the problem is... i know exactly what your talking about and im getting a new one through my local gm... thanks guys....

 

Your welcome
