I am trying to locate the rear heater core in a Chevy G20 1992 van. Apparently there are two.
Found the front. Where is the back?
Thanks!

find the rear vents. Then follow the ductwork back to the source. Possibly the rear driver's side? They are pretty big and hard to miss, so I imagine there would be a large piece of paneling to cover it.

Thanks. Tomorrow morning I will be on that core.
Hopefully I will see it.
My van is m life. It is all I have. (US ret.Marine,).
I was getting ready to junk it, because I am too old to work on it. ( I was a car mech all life/machinist).
BUT it is a nice cocoon, and I can run to the mountains and sleep in it....
In February, suddenly stopped. No crank, no start.
I have been stuck on it all these months, because I lost feelings in my hands ( surfing accident) and I don't feel the tools.
It took me two weeks to change the starter located under passenger wheel.
And now I am taking slow and thorough steps to replace the heater core BUT....can t find rear ...
I will try your trip. Thanks a lot, man.
I will post my results.
Thanks, M.I.F.

The rear blower in my '93 was on the passenger side just behind the rear wheel well. Previous owner removed all components though. Heater components may be located in the same place or nearby. Tried to find some info in Clymer for you, no good info for location in there though.

Thanks a lot. Full day for me. This is The Day.
I will let you know when I find it, but...I am thinking of bypassing the rear, because if, IF IT IS LOCATED all the way in the back, I will have to tear down a nice NICE hand built bed + deck I put together.
The best bed ever! ( I have troubled sleep).
I get on top of the hills, and peace!
I'm crossing fingers to fix this heater.
For 5 years, I went fishing, camping without any heater. Makes a difference when you go North.CA.
I am tired of freezing my a..
So, now I am working on a full scanning of the van, I will need a rebuilt engine eventually but this van keeps going. I was giving lots of care, until I twisted my neck in the ocean.
And ever since, doing car work is hard.
Doing everything is hard.
They want to do a spine fusion, but the chances of ending up like a cook on a wheeled are high.
So, I keep moving, pretending I can still push it.
And I am outstretching myself.
I do not have a garage. I have to work around my parking space. Hard.
And working under the hood is ok.
Working under van itself is ha hard.
Wish me luck.
I appreciate your help. Really, Thanks.
Next time,

Good luck. The shroud over the now non-existent blower sits roughly 1 1/2' from rear door on the passenger side. Fairly easy to reach from the rear. Since mine's empty, no clue if the heater components are actually there also.

Tough day. My hands don't grab/feel.
I pulled it all apart. Doing core step by step.
I will check on the tip you have me.
