Air is leaking at the piston guide bushings. There is increased thrust due to valve issues. There is excessive side loading in rotary applications. The piston seals are leaking. The power voltage isn’t correct. The control voltage isn’t correct. The fuse has blown. There is a power board failure. The wire has become fused or disconnected.
Can a faulty heater control valve be repaired?
To repair a faulty switch, you sometimes have to replace the heater control. Depending on the amount of vacuum, the vacuum motor will close off the flow of engine coolant fully or partially. However, even if the heater control supplies vacuum the mechanical portion of the valve can fail, preventing the heater control valve from closing.
