Each pack has one Air-Mix valve, and they are not common between both packs.

But I'm confused between your saying that you must select a warmer temperature, but yet drive both mix valves to full cold. HUH???
|Quoting Jetlagged (Reply 3):|
The pack controller will automatically drive the air mix valve to full cold if the pack trips. The crew should select a warmer temperature before resetting the pack(s).

He also posted on a 737 specific forum. It turns out his question was about the -800, so no air-mix valves involved.

but the air re-enters the system at the ACM turbine discharge (mix-muff) instead of the mix chamber.
