Fan speed switch not working.

This is a common problem. At first the connector on my resistor pack failed. Then the motor stopped working unless I wacked it. It's all working now. Here's my write-up with pix and fix info:

I just completed mine. Used parts 87138-04052 and

$31 82141-04M40

82141-04M40, both Toyota Genuine Parts along with some 16-14 Gauge Butt Connectors I got from O'Reilly's.

Took maybe 15 minutes and was not that complicated at all.

AC now works on all speeds. Yeeeehaaa!!!

 

After having fixed this several times on Toyotas, I got tired of paying for the fix and tried a coronary bypass on the troubled wire.

1. This is where the trouble starts:



2. I made a mark on the resistor to note where the troubled connection hits the resistor:



3. On the same side as the mark, there is enough open space on the black base to drill a hole big enough for a 12 gauge wire:







2. I soldered a wire to the base of the resistor and pushed it through the hole:



5. Moving the soldering rig to the passenger footwell, I scraped off some insulation and soldered to the troubled wire on the other side of the connector, creating a bypass around the clogged artery:



6. Added some black tape and reinstalled the resistor:





All told it took about 45 minutes to do, and since there was some 12 GA wire laying around here it cost zero dollars. I did this 6 months ago and it's still holding so I am calling the "coronary bypass" a success

 

I guess thats one way to fix it. You might try upgrading to the new resistor.

 

Haha, I was shocked when I replaced mine and found that the stock part looked like something out of a terrorist suicide bomb.

 

Thanks for this thread. I had this same issue and replaced the resistor today. All the fan speed settings work again!

 

Yep thanks bfuckin rock and roll!

 

I had to replace my resistor using this tutorial and it fixed my fan issue. Sadly the "NEW" resistor Toyota is selling is still a big monsterous piece of crap and burned out within 6 months.

 

I let the dealer fix it since it was still under warranty and the new resistor lasted 3.5 months.

 

THIS!

It's it will probably bend again, but it was obvious this was caused by the lack of contact between harness and pin (arching, heat). Cleaned up, bent contact back up, coated with dialectic grease. Working fine.

 

Thanks for the post. I just registered to Tacoma world and it is awesome. Can't believe I've never looked into this site.

 

Thanks! My fan has been intermittent for awhile. going to go check out the harness this morning. Might grease the fan bushing while I'm in there.

 

Probably a stupid question, but where is the best place to order these parts???

EDIT: nm......I just pasted the part numbers into Amazon and found them. The only thing I couldn't find there were the "connectors". Is that just the crimps, and if so, can I just use regular old wire crimps? What gauge of crimps are needed with the new part #'s?

Excellent write up!

Thanks for posting and sharing.

My 07 just started doing this last night, and I am not excited.

I spoke to my service manager and there is a TSB on this exact problem. Therefore hopefully not a dime out of my pocket.

However mine is currently working again so I cant have him diagnose and do the TSB just yet, for now I just need to get down there and checked out how bad this resistor is fried.

Thanks doe the fix!!

 

Yours is a 2007 and is well past the regular warranty period. TSBs for free are only during the 36Kmile / 36month warranty period. After that I would expect to pay. Not wanting to pop your bubble, I would rather you know the facts before you go to the dealer.

Recalls are always no charge.
TSBs are free during warranty, paid after.

 

If you just want to fix it per the TSB, it should cost you about $40 to DIY. I installed the new resistor and spliced in the new pigtail connector in about an hour the other night. You can read my personal thread about this ordeal here: https://www.tacomaworld.com/threads/another-fan-motor-thread.388963/

Everything is working really well after a new cabin air filter, new resistor, and new pigtail connector.

 

Me too. Did mine a week ago. I have an 08.

 

I have an '06 Tacoma, and I have been fighting a similar problem for about 2-3 years. The fan was intermittently working, and would always work if I turned it on high and pounded on the fan unit. This was fine until that stopped working, I looked through the posts, checked the resistor wires, resistor, checked the air filter, pulled the fan to make sure nothing was caught in it. Nothing seemed to work, as a last resort I pulled the fan out and took it apart, cleaned everything and re-assembled. When I put it back in the vehicle, not only did it work, but I have even more airflow than ever before. Here's a picture of the "dust."
