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 or you can check my other postings on this forum for additional information.

Where is the heater fuse for a 94 Ford Ranger?

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.

Where is the blend door on a 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, or follow the Google ads on this site. cgallen

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.

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.
