Remove the squirrel cage from the carrier in the engine compartment. You can reach in and feel it. Those were prone to break on rangers and explorers (Don't change from dash, floor, defrost etc. with the fan on high). If you take it to a dealership the will charge you 5.5 hours to change it. If you feel brave you can change it with a crow bar though said squirrel cage opening. prying up and sliding new blend door in place. You have to purchase a new carrier to get the blend door.
This is the hard way. The easy way is the HeaterTreater kit at www.heatertreater.net or you can check my other postings on this forum for additional information.
There isn't one. There'll be a fuse for the HVAC blower, but the heater itself doesn't use electricity (other than the blower fan). That year Ranger should have cables going to the blend door, so there won't be electricity there.
how to replace a blend door actuator on a 1999 ford ranger
The blend door sits vertically in the heater box behind the glove box. If you fully open the glove box, you can see the actuator motor on top of the heater box in the upper left hand corner. On the bottom of the box is a "pedestal" that is the bottom axle point for the blend door. The door axis is between the motor axle and the pedestal. If you are having issues with a Ford Ranger blend door, you can find diagnostic procedures with pictures and a cheap easy solution to the problem at HeaterTreater www.heatertreater.net, or follow the Google ads on this site. cgallen
It sounds like the heater blend door is not working. Unfortunately to gain access to the blend door for repair or replacement requires removal of the entire dash assembly. Big Job. I would suggest purchasing a shop manual for that vehicle if you intend on doing this job yourself.
The heater blend door is not run by vacuum. It is run by an electric actuator.
It does not. It is cable controlled thru a "blend door". If you are having no heat, it could be because of a clogged heater core, or the cable has came off the blend door, or the blend door control.
Sounds like the heater control valve. It could be the blend door actuator motor,which is located on top of the heater housing. this is what controls the fresh air flow through the heater.
How do I locate the heater blend door actuator in a Ford f150 pickup
I do not have heat in the car and the blend door clicks. How do I access the blend door in a 2005 Ford Explorer?
First check the fuses then check your blower fan then check the blend door and blend door actuator and then the control panel
Changing the heater temp blend door actuator requires removal of the dash assembly. Big Job. You will need a shop manual to attempt that one.
Low on coolant, stuck open thermostat, plugged heater core, faulty temperature blend door,
Yes, it is possible the blend door is broken in the heat position.
The heater core is like a small radiator - the engine coolant flows through the heater core . The blend door mixes varying amounts of unheated air with the heated air to regulate the temperature
You either have a bad a/c heater controller or a bad or weak a/c heater blend door..........
How to unlock a buick roadmaster
Plugged heater core. Faulty temp blend door mechanism.
either need a blend door accuator or a heater box
Low on coolant. Bad thermostat. plugged heater core. Temp blend door malfunction.
The temp blend door actuator is located on the HVAC unit behind the dash assembly. To replace the temp blend door actuator the dash assembly needs to be removed. This is a fairly large job with to many steps to post here. If you intend on doing it yourself I would recommend purchasing a shop manual for that vehicle. The manual will pay for itself after the first job.
Deep under the dash next to heater core
Mercury Mountaineers have a "blend" door in the heater box. It is probably malfunctioning. You can find more info by searching for Ford + "blend door" or "no Heat"
There is a mechanical lever on top of the heater that you can reach if you remove the plastic covers under the dash, just flip it to the other side.
It sounds as though the blend door in the heater ducting is stuck open. In a vehicle as new as the Dodge Magnum, this can be fixed by calling the nearest auto parts store for a replacement blend door actuator and replacing it by following the instructions in the package. If no instructions come with the part, you may need to invest in a repair manual which can also been obtained at the part store.
