1995 Ford Ranger Heater Blend Door

Most of the time my heater works fine. During very cold weather, I don't get
much heat. My Ranger has an electrically controlled blend door. My mechanic has checked and flushed the heater core and replaced the coolant, but the problem continues. Since it only acts up during very cold temps, the blend door may only need lubrication. I would to know where it is and how to get to it.

Click on the link.
I know you didn't want to remove it, but.
I don't know if you could get at it through the glove box cavity? As far as loosening the instrument panel, I'd have to look at it.

SOURCE: Need to find and fix blend door on 2001 Audi A4 Quattro 2.8L

you would have to remove the dash. i would first check the auxilary water pump to make sure it's not leaking. if your car has electronic climate control turn the heat on low with the engine off the change the temperature and listen for an electric motor sound to see if the blend motor is working.

You just might have an air lock. Try bleeding the system from the heater hose at the firewall. Losen one hose a little, and at operating temp. open slightly to let air out. You will lose some coolant, but just refill the rad. Now, both hoses should get hot.

No heat but a/c ok

Either your heater blend door is stuck or the vacuum line to the blend door has fallen off.
Was your heater working before? It is possible that the heater core was bypassed due to a leak (not uncommon in Ford products).

Need heater hoses diagram for 1996 Ford Ranger 3.0

Hooking up the heater hoses wrong would not cause your problem. I would make sure the system is full of coolant and has no air pockets, and then check the blend door under the dash.

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!

My 2001 ford ranger heater blows out cold air,what might be my problem??

If you are sure the engine is getting up to temperature then your problem will be a part called the electrically positioned blend door and or the little motor that moves the blend door. The blend door moves back and forth between the AC core and the heater core to provide a mix of hot and cold air or hot or just cold depending on what you set the air temperature control at, blue being cold and red being hotter. This is all to common a problem on Ford rangers and Explorers which share the same components of the heating and AC systems. When the door fails it is usually on the cold setting position. The kicker here is that you must remove the dash to replace the parts, the blend door and the blend door actuator motor should both be replaced at the same time, the common reason for the motor to fail is a sticking hard to move blend door due to warping of the plastic it is made from.

The fan works, air conditioning works, but the air wont heat up(knob turns to hot on thermostat). is it a vacuum hose problem, and how do we get to it?

The most common cause of this in the Ranger and the Explorer is that a part called the air temeperature control blend door acuator or the blend door shaft that the electric actuator moves has broken, this door is what shuttles between the heater core and the AC core and provides either heated or cooled air, or a blend of the two hot and cold air streams.

93 ford ranger blowing cold air only on heater setting. where do I begin troubleshooting, also I read about the heater treater blend door. Is this a high probability as my problem?

Check if the blend door is working, do you hear any operation or change when temperature setting is changed? If not, possible blend door problem. Or do it is that you have heat at the floor and not on your face, it could be a mode door problem. If neitherr, then check thermostat? Hold hoses to and from, should be firm. Heater core itself can be plugged on these models. You can check the temperature of the inlet and outlet hoses at the firewall with an infared temperature gun. They should be equal. If drastic difference, core is plugged. Backflush the heater core if this is the issue. If improves and returns, new heater core will be required.
