My blower doesn't work on its lowest setting, so I'm thinking of replacing the resistor pack if its not too expensive.

Does anyone have the part number?

Also, I've read that it resides behind the glove box, is it relatively easy to replace?

Plug in your VIN at one of the online Toyota dealers and behold the miracle of online shopping.

Toyota is great for having several part numbers for the same part.

as was said plug your VIN

As to easy to change one never knows at any time the simple things can become a major problem

I was near the dealer earlier so I just dropped in and had them order it, it's

87138-35050

I'm a bit concerned as it's called a "RESISTOR", when I was under the impression it was a PACK of resistors (one for each of the lower speeds). If it's only a single, I can't see how it would fix my issue. Can anyone chime in on this?

It is a resistor assembly looking at the print for my 97 4Runner the plug has 4 pins 3 for the different speeds and one for ground.

Just what year are you working on.??

I am not sure just what year Toyota changed things around in the earlier years high speed was direct meaning the resistor was bypassed.

Now in the newer vehicles it looks like low speed is direct which makes no sense.



Your blower motor does work on the other speeds??

You checked that your switch is working in all the positions ??

This will fix your issue if the blower motor resistor is the problem!!

Better to figure out just what is wrong first.

If you don`t own a multimeter now is a real good time.

Yeah blower motor works on all but the lowest speed. I suspected the switch at first but after looking online I was seeing that the resistor assembly was the most common failure. I figured I'd try the resistor assembly first since it's supposedly easier to get too. I have a multimeter, so I can test it when i get to it.

I've had the dash trim off before and would prefer not to take it off unless I have too, paranoid about breaking clips and getting extra interior squeaks (the result of the last time I removed/reinstalled)

Whats involved in getting to the resistor pack? I'd like to see a step by step if possible, its my DD so I can't have it sitting apart for long.

Anyone have a step by step for this? 3rd gen 4runner

Here ya go:

1. Remove the glove box by unlocking it then removing the two (2) screws in the lower part of the glovebox.
2. Remove the horizontal bracket by removing the three (3) 10mm bolts.
3. Disconnect the plug from the socket of the resistor.
4. Remove the two (2) screws that hold the resistor.
5. Pull out the resistor and replace it.
6. Reinstall the parts by following the reverse of step 5 to step 1.

The resistor in my '91 truck was a series of bare metal coils laid out on a plinth---looked like something Guglielmo Marconi might have built in 1912; It failed about every five or six years in the old '91.
Flash forward to '97(current 4runner) and the blower resistor is a more modern looking unit with the resistor elements encased inside a ceramic block. Progress? I hope...
