My heater won’t blow hot air anymore unless I’m going at highway speeds. Did some research and looks like it is the heater control valve that needs to be replaced. Having trouble finding an older version for my 2004. Only see lots of options for newer models. Can I put a newer heater control valve in my 2004? Or does it have to be like the one I have now? Having trouble finding a replacement part that looks like the one I have.
