Here are some of the warning signs of a bad heater control valve: no heat comes out. heat is always on and you can’t turn it down. heater operates erratically, putting out more or less heat without any control changes. coolant leaks. low coolant level. higher than normal temperature gauge readings (from loss of coolant).
