1957 Chevy Bel Air heater controls ventilation system

Today we review how I rehabbed the heater system with a new heater core, replaced the blower motor gaskets, new ventilation control cables and how the whole system works. Heater cables are prone to rusting up and freezing over time. It’s best to replace them with new ones. I tried out two sets of cables. The first set was not good and kinked immediately. I bought a second set from Route 66 parts. They are great!! https://www.rt66restorationsupplies.com
