Location of 3rd Gen Heater Core

Anyone accessed their heater core or climate control module? Where is it located in the truck? I cannot seem to find any schematics online showing the location, only the part assembly.

Please share any links. Much appreciated. Thanks!

 

I don't think anyone has had to mess with a heater core yet, but it's a safe bet that it is behind the passenger side dash area. The CCM is also probably buried deep in there also. Weird that you can't find the schematics online.

 

Heater core in the Air Conditioner Unit Assembly. The AC Amplifier assembly is also back there.

Excellent. Exactly what I was looking for. So since it's centrally mounted under the radio, I could see a small leak in a hose connection working it's way under the drivers seat. Though I would think you'd smell it in the vent, right? Perhaps it's a residual smell from a previous leak. Great info, gives me some better ideas how to check this out. Thanks!
