Can you buy new brushes for these ? I’ve saved many home extraction fans just doing similar to you , clean with air , then contact cleaner and then lube the fan sleeves

 

yes you can.. Just take the old ones out and get the width and hight, the do approximate length... if you can't find that in amazon, et, just measure width and height..

I actually removed the spring, to just check them out, and saw they had good amount left, so did not worry in measuring, but in the past, even when I could not find right away the right measure, I bought them a big bigger, and did sand them with fine sand paper, and in the end facing the motor rotating core, I did sand a concave surface to match the round surface, but you don't have to do that.

If you want to go hardcore, can always do what this guy did, buy a graphite block, and and build your own..

 

These here at Amazon measure 8 mm x 9 mm x22 mm , so you need to check w=the width and height you have, then compress the spring, and get an idea for the depth.. and it won't be hard to find , even if you need to order slightly bigger, and sand a bit. Some have weird terminals in the end, that I repurposed and used on new brushes, by splicing the cable w small crimping metal splice, or you can solder.

 

Ok so diy only solutions ( which is fine ) , cheers

Blower wasn't working, I noticed that I had heat, and AC compressor engaged , but no blower . VCDS said blower buttons were working . Bunch of other errors , that I did not even worry about ,

So I removed the motor following this video and cleaned that sucker real well w a can of compressed air , hand brush , and electronics spray cleaner ...

Removed the terminals from the resistor , and applied 12v current w 2 wires from battery directly to the motor , and noticed that the motor was working real well.

Since I saw so many reports of blower problem and resistor , I bought one from Amazon for 30 bucks .

I had checked the refrigerant pressure , and noticed I had no warnings, even though can't find the refrigerant pressure anywhere .. 🙄🤦maybe I am not looking into the manual properly, which is a great possibility 😂.. latter will look into that again..

Could not find resistance values as usual , either for the resistor pins , or blower motor , I just noticed they were different, when the new resistor arrived as noted in the pictures .. the resistor installed in the motor is the new one, outside the old one, btw. I have no idea what those numbers mean, just noticed they were different.

- That indicates that the resistor was indeed the culprit , and all is now working as it should ,& will have to check the refrigerant latter.

Btw: the brushes on the motor still had a lot left to go, so I did not need to replace them, and add new ones ..

This motor was really dirty .. when I sprayed compressed air before I sprayed the electronics spray cleaner, there was a lot of black dust coming out.

Just having lots of fun friends, while saving money , and at least this time , it wasn't that complicated .

Awesome job!
I re-read this a few times but can only assume it works and also works on each speed selected w/no problem as I didn't see it written.

 

It's working ! Almost broke it again, though .

Next time will ask Siri to write the how to ..

 

@New2Tregs
and thank you for the compliment.

Due to thousands of requests, turning into millions , the reading on the new resistor, on K setting or 1,000 omhs, was 0.541.

So I think based on my understanding, that the new resistor had 541 omhs , and the existing bad one 983 omhs, if I understand this correctly, and welcome higher powers to confirm this.

You are correct with the Ω readings.
If you use Ohms Law you can understand why a higher resistance would cause functionality problems with the motor for the blower.

 

How many miles on your Treg? I literally just did this fix about 2 weeks ago and I'm at 230k miles on my 2014. Ordered a $40 resistor on a random website since I wasn't 100% sure it was that. I had taken it apart and applied 12V with the resistor and then without the resistor and it spun up just fine without the resistor. Also had 12V supply from the car. Just wasn't sure if it was the controller or something. Works great now tho and a fairly painless job actually to change. Not sure what failed, I looked for any shorts on the circuit board and couldn't find anything.

 

@Snow60X 117k miles .

I saw that this is a common issue, even for cars with less than 100k miles . Fed gov has advisory somewhere nothing that there is a print defect on many of these resistors , that causes failure .
