If you're talking about the lever on the passenger side of the rear heater, it's on the heater valve and shuts off or allows flow through the heater core. Pulled toward the front of the van allows flow (and heat). In the summer one normally repositions that lever toward the rear of the van. You want that valve open (towart the front) when bleeding the cooling system.

I once thought I had a leaky core and found it was only the O-ring where that valve attaches (my '84). the '85 did in fact have a leaky core and was bypassed when I first got it.

That valve is only in one line so the rear heater is still subject to coolant pressure whether the valve is open or shut. the heater core cannot be isolated with that valve. You did the right thing to bypass it until you can replace what's leaking.
