Where is the heater control valve for a 93 Chevy van, G-20, 5.O
On a 1994 Chevy G20, the heater control valve is typically located in the engine compartment, near the firewall. It is usually connected to the heater hoses that run from the engine to the heater core. You can find it on the passenger side, mounted to the firewall or near the intake manifold, depending on the specific engine configuration. Make sure to check the service manual for your vehicle for precise location details.
Personally I do not know about a G20 1990 Chevy Van but the basics of heating are, the thermostat, heater control valve, heater fan and heater matrix. Does the van overheat at all, engine wise? Could be possible the system just needs a flush out. When you turn the heating dial (presuming it is a dial) you should hear a clunk which normally indicates the heater control valve switching over. Other than that, I've said all I can. Hope to be of some help, hope you get it sorted out.

To clean the control valve on an Infiniti G20, first ensure the engine is off and cool. Disconnect the negative battery terminal, then locate the control valve, typically near the intake manifold. Remove it carefully, clean it with a suitable cleaner (like throttle body cleaner), and use a soft brush to remove any build-up. Reinstall the valve, reconnect the battery, and check for proper operation.
