I installed 2 cutoff valves to get around a faulty DCCV ( for AC ). Worked great all summer but now the heat won't blow hot when valves are opened. DCCV solenoids stuck in closed position? The hoses seem warm enough so I'm not sure. Clogged core...I doubt. Any clue. I think I have to bypass DCCV completely , which I haven't done. AC and heat will just have to be regulated by fan speed.....lol.
