Heater control valve
Where is the heater control valve located on a car
Experienced mechanics share their insights in answering this question :
Hello. Typically the heater control valve is in the underhood area mounted near or on the engine compartment firewall. In that location just look for the valve plumbed into what are typically 3/4 flexible rubber heater hoses (often "molded" hoses), one hose "in", and one hose "out" of the valve. Until recently, these valves were mechanically operated via a cable. So, you might see a cable attached to a lever on your valve. With the trend to more electronic controls, on newer cars the valves can be controlled electronically, in which case you will see a wire and plug connection to the valve and no cable or lever. On older cars, sometimes the valves get sticky as the cable, sheath, and lever accumulate dirt and corrosion. You can lightly lubricate the cable and lever with an appropriate lubricant that is safe for rubber and plastics. If you have been directed to this valve because you suspect it is involved in a malfunction or repair issue, feel free to rely on YourMechanic to diagnose your heater control valve issue and help you with any needed repairs.

The heater control valve (sometimes called the hot water valve) is used to control the rate at which coolant flows through the heater core. The valve is located on the heater inlet hose.
Some heater control valves will be located in the engine compartment at or near the passenger side firewall. Others are located behind the dashboard near the passenger footwell. Refer to the factory service manual for your vehicle to determine the exact location.
The heater control valve (also known as the hot water valve) is the component that collects some of the hot coolant from your engine and diverts it to the heater core.
The control valve is used to control different parameters of fluid, by which the required specific task is completed in a proper way as desired. The other functions mentioned in the options are the functions of the Direction control valve. Sequence valve and hydraulic fuse respectively.
A mechanical thermostat uses two strips of metal, laminated together in what`s called a bimetallic strip in the thermostat`s sensor. As the temperature of the house goes up and down the two different types of metal expand and contract, and this switches the electric circuit connected to your heating system on and off.
The flow of coolant from the engine to the heater core is important. The only way that this flow is regulated is by having a fully functional heater control valve. There are a number of things that can mess the coolant flow up, like damage to the heater control valve.
The heater control valve allows the flow of coolant through the heater core to be controlled and switched on and off without affecting the operation of the rest of the cooling system.
Difference Between Solenoid Valve and Control Valve
A solenoid valve is an electromechanical device used to control the flow of fluids. A control valve is a mechanical device used to control the flow of fluids. Solenoid valves are more expensive than control valves. Control valves are more durable than solenoid valves.
The flow of coolant from the engine to the heater core is important. The only way that this flow is regulated is by having a fully functional heater control valve. There are a number of things that can mess the coolant flow up, like damage to the heater control valve.
Heater doesn`t work
If the heater control valve breaks or gets stuck, the coolant flow to the heater core may be restricted or stopped completely. Without coolant flow to the heater core, the heater will not be able to produce warm air for the cabin.

Overheating issue, when heater is on its normal temp. but if heater is off it begins to overheats, until heater is turn on again.
ANSWER : It sounds like your engine might have a restriction in the cooling system. If the cooling system has a restriction that prevents its flow, this will cause the engine to get hot. The heat is dissipated from the cooling system by means of the radiator.
When a restriction exists sometimes the radiator alone is not enough. The heater core is like a small radiator inside the dash and is also another means of dissipating the heat from the cooling system. So essentially when the heat is on you are introducing a second radiator into the system which will help to cool the engine down.

Evaporative Emission Control System Purge Control Valve Circuit Malfunction how to fix and where is it ?
ANSWER : Hi there. The best advice I can offer is for you to complete one of two things. First, it would probably be best to have a professional mobile mechanic come to your location and complete a check engine light inspection so they can pinpoint what part of the EVAP system is causing your failed emissions test. If you decide you want to do this on your own, then it would be a good idea to purchase a service and repair manual for your Ford Mustang – so you can look at detailed diagrams and replacement instructions.

Where is the heater control valve located?
ANSWER : The heater control valve is located in the engine compartment, on the firewall. From the illustration, it appears to be either in the middle of the firewall, towards the top, or on the passenger side. There will be a couple of hoses running to it, and a mechanical arm with a cable running to it.
If you need some assistance with the replacement of your heater control valve, consider YourMechanic, as one of our mobile technicians can do so at your home or office.

Yesterday my heater control valve broke. so I replaced it but it still overheats and there’s no heat. Should I replace the t-stat
ANSWER : You will need to have the a/c controls in the heat position when filling up the cooling system to get out all the air in the system. You may need to replace the thermostat if the engine was overheated bad you may have blown a headgasket. Once all ait is out of the system check for overheating. You may need additional work to fix the overheating if the engine was allowed to get too hot when the valve broke.

ABS, ESP, EBR malfunction
ANSWER : You’re getting into an area that is kind of a dark art when you’re getting these kinds of codes. While I don’t know any of the symptoms that the car is exhibiting, I can tell you that failure in one of the control units can lead to codes showing up in the others and the ABS, ESP is a likely culprit since it interprets the wheel speed signals and sends the information to the other modules. You’re right that the module has to be coded, and I don’t think that Snap On has the software for that so the only place to go is the Star Diagnostic. (The consumer version of the Mercedes SDS ) You can Contact YourMechanic and see if anyone in your area has the appropriate equipment for this. Otherwise, this may be a case that would best be consigned to the Mercedes Dealer.

Does my 2012 Ford Escape have a heater control valve?
ANSWER : Hi there, thank you for asking about your 2012 Ford Escape. To answer your question, no, your vehicle does not have a heater control valve. Hot coolant will continually move through the heater core as long as the engine is running. The heat is isolated within the hear core box to keep the interior air from heating up when the heater is not in use.

Heater control system will not power up even though there is power to it
ANSWER : Hi and thanks for contacting Your Mechanic. When the penny was in the cigarette lighter, the penny act as a conductor and shorted out the circuit. The cigarette lighter is either powered all the time or powered when the ignition switch is on, but either way, the cigarette lighter is tied through the ignition switch. Check the fuse box for power to it and ground. If the fuse box has power and a ground, then the ignition switch burned from the short in the cigarette lighter. This would explain that phenomenon light issue and all of the electronics failing in your vehicle. Check all of the wiring to the ignition switch and the main power to the switch. If there is power to the switch but no power coming out of it when the key is in and turned to ACC or ON positions, then the switch needs replaced. If the switch is working fine, then the fuse box has a short in it and it needs replaced. If you need further assistance troubleshooting your massive electrical outage in your vehicle, then seek out a technician, such as one from Your Mechanic, that can assist you.
