No cabin heat in Dodge Grand Caravan.

So the most important question to answer here is, Where is the antifreeze going? Is it running out onto the ground? Is it steaming out through the exhaust when the engine is running? Or is it draining down into the oil pan where it can cause the most damage? You must tell us before we can give you an answer to your No-Heat question. I hope this is a help, or at least a place to start helping?
