Q: Where is the heater control valve located?

Where is the heater control valve located

My car has 158000 miles.
My car has an automatic transmission.

The heater control valve is located in the engine compartment, on the firewall. From the illustration, it appears to be either in the middle of the firewall, towards the top, or on the passenger side. There will be a couple of hoses running to it, and a mechanical arm with a cable running to it.

If you need some assistance with the replacement of your heater control valve, consider YourMechanic, as one of our mobile technicians can do so at your home or office.
