Hot air into car when HVAC off
« on: July 01, 2021, 09:25:04 AM »
67 with factory air

Once the engine is at temp, I get hot air into passenger compartment when the system is in the off position. I have to assume the blend door before the heater core is not sealing complete or the door is out of adjustment. The air is coming out of the vents and not through the firewall.

Is there any other reason this would happen?

Thanks!
