Have you checked you heater control valve or heater core if working properly.
the heater control valve or DCCV (dual climate control valve) is located next to the radiator on the passanger side just below the high pressure side service connector

The heater control valve is located on the front part of engine compartment. Its next to the radiator on the passenger side.
Most likely it's the heater control valve. If the heater control valve leaks a little it can allow a small amount of heated engine coolant to circulate through the rear heater core.
The heater control valve on a 2004 Toyota Highlander is typically located on the engine compartment's firewall, near the passenger side. It is connected to the heater hoses that run from the engine to the heater core inside the vehicle. Accessing it may require removing some components for better visibility and reach. Always consult the vehicle's service manual for specific details and diagrams.

No. There is no coolant flow valve.
