Re: Electric Heater?
Those little space heaters that people keep under their desks are typically 1200 to 1500 watts. If you could find something similar for 12V, it would draw 100Amps +/-. J C Whitney sells some little ones with from 10-12 amp draw. You'd need 8-10 of them at $16 to $27 each. Of course they would be easy to mount where you needed the heat.
They also sell a 12v hair dryer with 12 amp draw, about 160 watts for $10. Again you would need about 8-10 of them. For comparison, a standard 110V handheld pistol style hair dryer is 1500-1600 watts.
A standard space heater could be run off an inverter, but a 1500W inverter is about $400.
If you're totally against repairing/replacing the OEM unit, there are under seat and under dash (looks like the add-on air conditioners) models. Check in hot rod magazines.
The salvaged auxiliary out of a van or a set of Carhartt coveralls would be the cheapest options.
