Where is the blower motor resistor. Please be more detailed than the last response. I'm a carpenter... not a mechanic. Picture maybe?

The blower resistor in a Toyota Townace Noah with a 3S engine is typically located near the blower motor, which is responsible for directing air into the vehicle's cabin.
Here is a general guide on how to locate the blower resistor in a Toyota Townace Noah with a 3S engine:

1. Locate the blower motor: The blower motor is typically located under the passenger side dashboard, near the footwell.
2. Identify the blower resistor: The blower resistor is typically a small rectangular or cylindrical component that is connected to the wiring harness near the blower motor.
3. Remove the blower resistor: To access the blower resistor, you may need to remove the cover or the panel that covers the blower motor. You can then unplug the wiring harness and remove the mounting bolts to remove the blower resistor.

Note: The location and accessibility of the blower resistor may vary depending on the specific model and year of your Toyota Townace Noah with a 3S engine. If you are unsure about the location or how to access the blower resistor, it is recommended to consult a professional mechanic or the vehicle's owner's manual.
It is important to handle the blower resistor with care, as it can be easily damaged if not handled properly. If you are not confident in your ability to replace the blower resistor, it is best to seek assistance from a qualified mechanic.

Usually, when the resistor goes bad it will still work at high speed! check the connector to make sure is making a good connection!

The heater blower motor resistor is located underneath the dashboard in the heater/AC compartment.

Do not try this at home. For HVAC professional use only. This video shows yours truly changing a blower motor ...

Sounds like either the blower motor switch or the motor resistor has failed.

this is located on the case under the hood. here is a picture hope this helps

If it only works on high the blower resistor is bad.Would also check the connectors at the resistor and blower motor for poor,melted or frayed connections replace or repair as necessary.

First check and see if you have voltage at blower motor with key and switch on, with test light, if you do have voltage, blower motor bad, replace it, if you don't have voltage at blower motor, next to it, is where the blower motor resistor is at, follow the wire from the blower motor to it, check voltage there, should have voltage, if you do replace blower motor resistor, resistor cost about $45.00 at auto parts.If I can be of more help. please let me know.

This is what you are looking for. I've got a similar problem and need to get my blower motor resistor out. I've found the resistor, but it has no bolts holding it in. It has what looks like torx or something similar, but nothing will fit. In fact, they look like they are plastic and possibly stripped out. If you have any luck let me know how you got it out.

Yes its the blower motor resistor.

More then likley theres some trash or something in it, or possibly the motor itself is on it's way out. There not that bad to pull out of that body car, just pull it out and see what you can see.

The blower motor is under the glove compartment

You can replace the resistor on your own. Please find a detailed diagram which would guide you to do it.

Thanks

there is no relay for the heater fan it's a 15 amp fuse and is on the accessories circuit. the reostat is responsible for all 3 speeds .with the key off there should be no voltage to the blower motor whether the fans speed fan switch is on or off. the fuse will be located in the fuse paneleither on the drivers left side in the dash or underneath the dash in the fuse block. you have a short in the harness that is under the dash and most likely it's a bad plug on the harness. your going to have to do some searching but that's where the problem short is... please rate
