I am freezing my butt off driving my car. I have no heat and I believe several folks on the list agreed it was the monovalve, but I just want to make sure.
So pull it out (four screws, 5 minute job) and see if the solenoid is full of water and/or the rubber diaphragm is torn. Unplug its connector and you should be getting full heat all the time. It's your monovalve. -- Jim
