You could try just wiring up a standard little 120v electric heater. Resistance heating elements don't care if they have AC or DC flowing thru them. A 1500 watt heater on 120v would be roughly a 150 watt heater on 12v. I would think that might be about right to warm up the foot area under the dash.
The problem might be the fan in the heater. Ideally you'd find one with no fan but that would probably be kind of large. You might be able to swap out the fan motor for a 12v DC model.
That's an interesting idea, I'll have to play with an extra heater I have when I get home. Thanks.

The heating elements won't care, but the induction motor will. Best case, the fan won't run, worst case, the fan will burn up since it's designed for AC current.
Could use one of those quartz heaters that doesn't have a fan, but they're kinda big for down in a foot well.
