Extreme Condensation From Defrosting Vents Problem

[Lbcnu24]

I bought a car that needs total surgery. Everything has got to be replaced... It sat for a very long time.

My problem now is that condensation is heavy. It goes away with A/C on.

I have been refilling radiator with coolant/water over a basic period of time. Somehow, that coolant is leaking somewhere... but I dont know where...

There is no smell of coolant within the car.

The vacuum system for the engine needs redone.

What would cause this condensation and has anybody ever experienced this problem before?

This car puts out pretty good heat... No problem there...

I was thinking that since my vacuum system is shot, that the coolant may get consumed that way, but I am not a novice with Beamers... just am going through the motions until I am really in motion if you know what I mean ha...

Any advice would help y'all... and thanks in advance!
