The blower motor itself is the most likely cause. It is located under the dash on the passenger side. The plug is usually white with a black and a blue wire. Remove the plug and run a test light between the 2 terminals, turn the key to "on"(engine not running) with the blower switch on in any position the light should turn on. If it does the blower is bad and can be replaced by taking out the 3 screws that hold it in. if the light does not light, the wires and fuse need to be checked. The fuse is labeled "heater" and is under the dash on the drivers side. If the blower works on high speed but does not work on one or more of the lower speeds-- the blower motor is OK. The problem lies in the resistor block, usually found attached to the air duct slightly downstream from the blower motor. Look for a 3 to 5 wire plug-in attached to the air duct. Remove the electrical plug carefully, then remove the 1 or 2 screws attaching the small flat plastic to the air duct. Gently remove the part-- if it has little coils of wire on it, you found the resistor. Treat it very carefully as the wires are brittle. Presuming you look at the coils (and see 1 or 2 with breaks in them) go get a replacement from a junkyard (cheap but used parts), auto parts store, or Toyota dealer. The Toyota dealer part will fit like a glove-- but take your heart medication before they tell you the price.
Heater blower resistor is what controls the low medium high speeds...
Yes, located in the blower motor resistor pack. Follow the wires backward from the blower motor to find it.
toyotas have a resistor bank in line with heater motor each speed has a different value resistor. there is no resistor on high speed. it is located on passenger side in heater duct I thank it has two screws holding it on when you get it out you will see the resistors burned
The blower motor speed resister is burned out.
A bad heater blower motor resistor would effect one or more blower speeds other than high.
Probably the blower motor speed resistor is partially burned out.
blower resistor especially if its chrysler/jeep or blower switch
Resistor on the heater blower motor has failed
Blower wont work on all 5 speeds, usually the lower speeds tend to go first.
The blower motor resistor is defective. They go bad when the blower motor pulls to much amperage.
You have a relay located behind the glove box once removed to the left and you also have a blower resister that controls the speeds located on the passengers side in the blower motor housing..............
replace the resistor pack on the fanblower, under glowecompartment
Only for the high speed blower function. The lower speeds go thru the blower motor speed resister.
you need a new rheostat !
The blower motor resistor is bad.
If it has only high speed, the blower motor resistor has to be replaced to get all speeds back.
If all speeds do not work, suspect the fuse, the switch, the switch connector or the blower motor. If only high speed works, suspect the blower motor speed resistor. If low speeds work and not high, suspect the blower motor relay.
If the heater fan works on all speeds, then the blower motor, blower fuse, blower relay, and blower motor resistor pack are all good. If the fan runs but nothing comes out of the vents, you have a 'mode door' issue (which might include a bad control head).
Sounds like you need to replace your blower motor resistor.
the heater fan resister,it is or should be on inside or on outside heater box.
If you have only high speed on the blower motor or you are missing one or more low speeds, chances are the blower motor speed resistor is burned out.
The resistor block or blower motor resistor is used to control the speed of the blower motor. That is how you get the lower speeds on your air conditioning or heater. The higher the resistance the lower the speed of the motor.
It gives you all the blower speeds except high.
could be thermostat or heater fan if you can hear all the speeds on the blower motor working then it could be your thermostat but your heater core might be plugged as well
If you have no blower speeds at all, first check the fuse. If the fuse is okay I would suspect the blower speed switch and its electrical plug has melted. If the switch checks okay I would suspect the blower motor is bad. If you have high speed only, I would replace the blower motor speed resistor. If you have all lower blower speeds but no high speed, replace the high speed relay.
