As the title says, hot air coming through center and side ac vents. Car is a 72 with factory air that appears to function properly with a minimal amount of air flow however.
I currenly have top and front dash pads out, where/ what should I be looking for. Have been a car guy for a lotta years and worked on old Jags, but will admit to some intimidating looking work ahead of me. Thanks for all your help.
Additionally, any recommendations on replacement of any components living back behind the dash as I know I won’t want to revisit any time soon!

Thanks Lars. Is this a job done from inside or outside or both? In lieu of this, would disconnecting heater hose eliminate hot water going to heater core just allowing for ambient air sneaking into the cabin?
Many thanks
Dave

Thanks sambrand. I can see I’ll be facing a steep learning curve. Appreciate all the help. I get cold ac air from the center and side vents with ac on. However with system totally off I am getting warm air through the vents. Help Mr Wizard
