So this whole driving a classic car everyday is fun and all but I have a problem maybe some of yall know what I'm speaking of..

When I run my heater .. anti freeze comes through the vents .. the passenger side floor board was soaked in anti freeze the other day .. so now I've cleaned that shit up its still fogging my windows almost immediately after I turn my heater on ..

I'm thinking it must be the heater core leaking antifreeze .. but to be completely honest I have no fucking clue .. Please Help !
