Interior Heater Core

Hey everyone,

I've been working on gutting out the worthless parts of the interior in my 77 J10 and found something a bit surprising. On the passenger side of the Jeep, there was an entire heater core and blower fan tucked up under the dash. I'm pretty sure it's aftermarket, but the vents that fit just below teh factory dash sure looked like they belonged there. Anyone have any information on these things?

I'd love to see some pics. My big complaint about the Jeep's HVAC is that they're separate, I can't use the A/C to dry the air while defrosting. Although I have been mulling over some ducting ideas to see if I can achieve that.

I don't think it's an A/C system. There is no A/C compressor on the truck, and there are coolant lines that run to it.

The rest of the AC could have been removed by a PO. Or, I think it was on here, I remember reading something about someone converting their AC ducts into a heater to get more "in your face" heat, so to speek.

for reference, here's a pic of the stock AC ducts from a wagoneer,

Alright, that picture answered my question. It must be the AC unit. Anyone have any use for the core and blower? The vents and ducting are ruined though...

Next summer I'm putting a coolant shutoff valve in the heater line. Even with the heat off it still blows heat into the cabin. And after opening up the heater box I know why, when the flap is shut air still flows through the box, just not through the core. And the box gets heated by the core.
