Building a heater into rear defroster blower hose

That sounds like something the factory should have done. It would also heat the interior faster. My heater box is in my Duster without the core hooked up I use the defrost on sometimes. This gives me an idea to incooperate an ellectric element in the box. Some of the ideas members come up with on this site are real creative. That is one thing I like about this site. I can't wait to see where this goes. Steve
