Got an "Aria" heater in my 52 Chevy 3/4. It's hooked to an old lamp switch and it works great. The problem is that even though there are defrost vents at the windshield, there are no ducts and there is no outlet on the heater to duct to the windshield. What's up with that? Will need the defroster worse that the heater this winter. Any ideas?
