Make sure the heater core is in the open position by using the shut off valve and turning it to open. next, you may have a malfunction in the direction door the directs the air flow in the dash. a lever may have become lose or separated. may be a bad servo motor not directing the door to move to the heater position. i would start by checking that shut off valve first on the heater core.

SOURCE: ford ka heater blows hot air all the time

Taurus does not use a heater control valve. It runs coolant thru the heater core constantly. You may have a temp blend door actuator problem or a plugged up heater core is also very common. Feel the heater hoses, they should both be very hot, it one is much cooler; you can try to back flush the core.

SOURCE: heater blows cold air. I have replaced thermostat,

Not an expert by any means, but i know my ranger.. I had a small leak at the top of my radiator that still cooled the engine but didnt have enough pressure to get to the heater. The heater hoses travel up over the engine and just were not gettin anything to my heater core. That or make sure the heater control valve is operating.

Heater blowing cold air


1. Check coolant level to ensure full, and thus getting to heater core.
2. If that didnt work, With engine hot and running, and heat on in the truck, feel heater core inlet and outlet hoses at the engine compartment firewall to ensure both are hot an thus getting flow. If not the core is clogged or there is a faulty valve in the flow path.
3. If te hoses are hot there is flow thru the core and either your blend door is broken and shut or the blend door motor or circuitry is bad.
4. You tube Ford Ranger blend door for video on how to access behind the glove box. You can fairly easily remove the motor and undoing so check its operation and also the blend door operation.
Likely your motor has gone bad and can be replaced using a low profile socket wrench to remove the 3 Screws holding it in place. I bought a new motor for $40 at One o te auto parts chains locally.
Good luck!

1999 ford ranger 3.0 heater wont get hot. blend door is working. truck blows whatever the air temp is out side with heater on hot.


That means either you have a vapour lock, your water pump has failed, or your thermostat isn't opening. It is not easy for a non-mechanic to put coolant into a vehicle... more often than not you get a vapour lock. Sometimes this happens if you don't check your overflow bottle daily, (or weekly). If you have no habit of checking your tires, your oil, your brake fluid, your signals, transmission fluid etc then it is easy for you to neglect your overflow bottle. If the coolant gets all the way to the bottom then your radiator will start emptying daily into your overflow bottle and causing you problems.

Heater blows hot air only


You know you are setting yourself up for a fall when you say you checked everything.
Is the blend door working under the dash ?
It controls the vent temp.

Hot air cmes out the passenger side while in the ac mold


Usually a sign of a faulty blend door. The blend doors direct air thru the heater core and evaporator core depending on the temp control on the dash.

96 ranger the fan blows, but on hot setting, air is not hot


If the fan works in all speeds but is not hot, it is most likely the heater core that is at fault.

Heater blows hot air in all control settings 98 Ranger


There is small cable that runs from the back of the temp control switch on the console that goes through the firewall and loops around a valve on the heater hose that is used to control the amount of hot coolant that goes into your heater coil. This cable hooks on the back of the temp control switch also. Bad news, that's probably where it came off and you'll have to pull the control unit out of the dash to get to it.
