your motor could have burnt up, or your relay could be bad, or you could have possibly have a wiring fault
The relay on the heater/blower circuit on a Ford Escort MK6 is probably behind the glove compartment. There are two popular places that Ford puts its heater/blower relay switches. The other place would be next to the blower motor itself.
A bad heater blower motor resistor would effect one or more blower speeds other than high.
there is a resistor that controls the speed and should be near the blower motor its called blower motor resistor
The heater blower switch and the electrical plug attached to it may be at fault. Remove the heater control unit from the dash and inspect the plastic electrical plug attached to the blower switch, you may see it has melted. The switch and plug is available from your local auto parts store.
Most likely is a short in the wiring from your heating/cooling/vent controls to the blower motor, or simply the blower is going bad.
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.
1st check fuse , then or resistor and then blower motor itself resistor is usually under hood right by blower motor or on the ducking it self google images resistor for your kind of car so you know what your looking for power should be going into it when your heater is on and coming out the other side the higher the setting the more power coming out the other side going to blower motor
Possible options: * blower motor * electrical connection * switch assembly * resistor assembly * fuse There may be other possibilities but that's all I can think of at the moment.
The blower motor resistor assembly is located under dash on passenger side.
It's under the bonnet by the blower, it has a push and slide connector and sometimes a other 2 wire connector.
Assuming you're talking about the blower motor, because the blower motor resistor is faulty, and needs to be replaced. On the high setting, it doesn't go through the resistor - on the other settings, it does.
The Fuse/Relay box under the hood has a single connector that has power for all three running through it. Check that.
