The line (23) applies vacuum to the heater hose water valve (20) via the solenoid valve (22) that is on the firewall. From the solenoid, there’s a vacuum line (21) that runs down to the water valve. When the water valve is closed, coolant flow is blocked from the heater core in an effort to increase a/c cooling performance.

The solenoid is energized and the water valve is closed when the a/c panel temperature dial is turned to the “max” detent.

Here’s a parts catalog, the heater system is in section 8.
