5) When I call for AC, I get 12V on one heater valve but not the other - think this is my source of heat!

So - think this is my problem - why is one side calling for heat???
Could be IHKA is fubar, but I would like to troubleshoot more.
Problem is one side, so am thinking about which sensors have a L & R...
Bad Interior air temp sensor?
Perhaps a bad heater core sensor?

Has anyone found a way to read these sensors directly?
For troubleshooting purposes, try to disconnect the connectors of the heater valves to override the valves not to sending heat into the A/C system.
