some luck cleaning the contrl valve at the firewall

There is a DIY on rebuilding a valve that is relay controlled for the split climate control. If you look under the hood bside the ecm interface boxyoull see two sylinoid devices that open and close to let more or less water to the heater core. I am sure thay play a big role in regulating the heat per side.
Im sure it is under climate control/mono valve. I just looked it up
