They are entirely different systems. One does not control the other. You have a problem in your heater core, heater control, water circulation or hoses.
the heater control has a thermostat for the heater only. that thermostat needs replacing
most of the time it the heater control unit on the motor not the heater core had same problem
The water is not circulating through the heater core or you have a control problem. If the heater is putting out heat then it is probably a control problem. If no heat then - water pump out, low on coolant, or maybe the therostat is stuck open.
I would suggest replacing it.
Usually at the firewall either passenger side or middle follow the heater hoses
I had this problem once with a different vehicle. You may check the heater control. That may be the problem. Hope this helps.
It does not have a heater control valve.It does not have a heater control valve.
Passenger side, near the firewall inside the car.
usually it is a vacuumn problem right at the heater control switch or sometime under the hood
Low coolant? Bad thermostat? Heater core plugged or airbound? Heat control cable not working?
The heater control valve is used to shut off hot coolant from entering the core when the heater is in the off position. A heater control valve can be actuated by either a vacuum line or a cable from the vacuum heater control valve to the heater core. This hose should be warm; if not the heater control valve is stuck and needs to be replaced
Where is the the heater control valve??
There are signs that there is a problem with a hot water heater. When you cannot get your water to heat. It could be signs that the pipes leading to the heater are leaking. It could be a problem with the thermostat in the heater.
under the dash right hand side.
You would diagnose the situation to determine the source of the problem you're having. At that point you can decide what steps are needed to repair the problem.
where is the heater control valve
You can get a heater that magnetically sticks to the pan and warms the engine. You can get a heater that connects to the heater hose and circulates warm engine coolant. You can also get a block heater that replaces a freeze plug. You have to decide which works best for you.
The water pump pushes the coolant through the engine block and head(s) then into the heater core.
The heater matrix can be replaced by removing the heater core and temperature control cables. Replace the heater core and the control cables.
i have the same truck, their is no such item availbe for this year the closest one is 1993. if its a heater issue try back flushing the heater core, very very common problem.
I am having the same problem and I WA told it was the heater core. I am going to give that a shot. Autozone has them for $30.00
The heater control valve in a Mustang is located within the engine. It is right in the heater's core and where the coolant is located.
Blower motor, resistor, wiring or control problem are common causes
