it might be that the moter on the fan is starting to go. i have had that noise on two different vehicles and it was the blower motor. and it went with in 6 months to a year.
The heater fan ONLY blows the air, it does not make the temperature of that air. Your heater temperature controls how hot the air is. Adjust your heater temperature for hotter or cooler air.
AnswerIf it's a rapid clicking sound that becomes more rapid when the fan is turned up high, you probably have a foreign object like a leaf stuck in the blower.It sounds like your Air door actuator or temperature actuator
No one but you can decide. The whole reason for a water bed heater is to make the people sleeping on the bed comfortable. For that reason, the temperature should be raised or lowered according to your comfort.
Temperature control in dash by heater core is broke.
The best thing you can do to make your Oscar more active is to raise the temperature of the heater you have.
You need to find and fix what broke. The first places to start would be coolant level, engine temperature, and dash heater controls.
Probably a bad thermostat - stuck open so the water temperature in the engine block doesn't get hot enough to make the heater warm.
because god decided to make it like that
Check the coolant system to make sure you are not low. An air bubble going through the heater core can make an odd sound.
Pressure does not make any change in the speed of sound But temperature affects it. Velocity is proportional to the square root of kelvin temperature Humidity also affects the speed of sound. Higher the humidity more the speed
Not a whole of symptoms to work with here...The most common cause of "... heater not working..." is a failed temperature blend door actuator motor.See "Related Questions" below for more
Temperature makes different sounds because of the friction and volume involved, like for example a very high temperature would make a loud noise because it is working hard to get all of that temperature out of one place.Oh who am i kidding i dont know the answer do I.
