bypass heater core

Could be the cables are froze up & the heater was stuck in the "hot" position all the time...? They do put off a lot of heat. My heater box was froze up & stuck in the hot position with the heater core still operational. Summer time cruizing was a nut roaster!

Once I get it finished, I will never drive it in the cold months, so I have since made the duster into a heater delete car. So no more nut roaster!!
