Hey y'all haven't been on the forum for a while as I decided to just bypass the heater lines for now and plan to come back to this issue which I suspect as a few have said that it's either the heater matrix or the heater pipes. Decided this was the best course of action as I was really just trying to get it road legal and had other more important issues to fix..... Like front subframe rust and all my suspension needed to be replaced ðŸ˜ðŸ˜. But thanks again for all the advice and help!!
