Does anyone know of any write-up on replacing the resistors for a heater in a 99 4 runner. The heat works, but only on HIGH, the other three options or fan option will not work. The dealer said they would do it, but that it would be easier for me to pick up the parts and do it myself due to labor costs. I agree, only problem being I dont know how to do it...so I would like to find out. Thanks!

I don't think I have ever heard of that happening.

Is this on a limited?

You will need to get a Haynes manual or similar so you have wiring diagrams to go by. Those will also be some pretty high watt value resistors since a decent amount of current goes through the blower.

you only need the resister block, its been awhile since Ive looked at mine but i think you have to take out your glove box, it will be mounted to a heat duct, you will only see the plug, the resisters are in the duct so that air moving through the system can cool them, its not hard to change, just hard to get to....

Very easy to replace just kind of hard to get to just look under the glove box one phillip's head screw and plug.

Ouch! List price is $18 (2nd gen 4runner), you can get it from 1sttoyotaparts.com for ~$13. You're dealer is ripping you off

Do these places ship to Canada though? Cause if they do I need one as well and I'll order it through them.

I have never dealt with this part in any of my cars, could someone possibly post a pic? I have a 3.4l 99 4 runner sr5.

I just want to make sure I buy the right part. "The mechanic said the resistors are bad and that is why your blower for the heat/air only works on high"

Now on the lower setting you can still feel a little air flow coming out, but very little...all three alternate settings blow out the amount of air I would expect to come from the lowest setting.

Thanks for all the help!

lebeau

I can email you a pic.

Holy cow! 30plus tax shipped from Conicelli parts as opposed to 117 plus tax from a dealer here in Ottawa. With the Canadian dollar up into the eighties, it makes it much more attractive.

Lebeau -

Any chance you can email me that picture? Thanks!

I have a writeup with pictures for the repair on a 1st gen 4Runner on my web page:

The same basic steps apply to most Toyota vehicles.

Thanks! That was very helpful...The resistor from my dealer is like 90 bucks!!

Its for a 1999, but wow, that sure is different than 16 bucks...yikes...do you smell some bs?

firemedic

Yes, it is a ripoff, list price is $22.26, get it for $16.03 here: 1st toyota parts

Thanks!

Worked a deal with my dealership to get parts at cost...because they screwed me over on the purchase...got the part for 16 bucks...easy to install.

When I pulled out the old one it was literally fried, charred black and the circuits were all burnt up...part of the ceramic was actually cracked off the part and is still missing somewhere in the air lines.

Oh well..heat is working well now...and the wife is happy because her car is warm in the morning!
