Blower motor squeek / chirp on low *FIX*

just treated mine with frog lube paste and a heat gun. So far its holding up better than the last 10+ products I have tried.

 

haha nice, never thought of using that

 

DuPont Teflon Multi-use lube. I get it at Lowe's.

 

Got it!! Sprayed it in, and it is for sure quieter!

Found this too...

I've found the reason for the ticking sound. My dealer kept saying "normal" and "there are leaves in the fan". I kept telling them otherwise until I got pissed enough to just take apart the blower fan and see where EXACTLY the sound was coming from. The sound is coming from the metal faceplace which covers the wire spool around the spindle of the fan. the faceplace must be balanced properly because it holds in place the spindle which is rotating for the fan to blow. when the faceplace is off balance by one of two screws that holds it in place, the fan ticks like a MF'er....as you balance the plate, the tick goes away and is as quiet as a mouse.

#1 I took my glove box completely off making sure to release the springy thing first on the right side towards the passenger door and then just popped her out.

#2 I then got out my trusty ratchet with a 5.5mm socket and removed 3 screws on the underside of the blower....the fan will slide out easily. leave the wires attached (be careful as the fan is still runnin' lectric)

#3 let down the door that holds the cabin filter in and remove filter. now you can reach up in there and see if any of those mysterious leaves are present. blow it out with your air compressor or just root your hand around in there to get anything out.

#4 hold the black plastic fan housing in your hand carefully and reach over and turn your a/c on the low setting (BE CAREFUL as that thing is quick to get away from you and can take a nub off pretty quickly) make sure you can hear the sound coming from the assembly in your hand. If so, move to step #5.

#5 remove the covering with a phillips screwdriver (4 screws - i think) and remove that cover to reveal a silver metal cover with TWO (2) lubed screws. THESE ARE THE SCREWS THAT MUST BE BALANCED. Take a pair of vice grips and grab the black housing with them so you can get your hands away from the moving fan and so you can hold it steady. then use your phillips screwdriver on one of the two screws and notice how you can make the sound/tick worse as you tighten one of the screws.....too tight and the fan slows down and/or TICKS, too loose and the fan slows down....(spindle getting in a bind).

There is a point where the fan will turn fastest and the sound will disappear magically. You'll see what I'm talking about once you're in there adjusting the screws to find that perfect point.

#6 re-assemble and enjoy!

 

I tried this lubricant but it only lasted one day.

Ok, I've officially jumped on the Teflon bandwagon. The copper anti-seize I used only lasted 1 year. Instead I decided to go with the Tri-Flow dry lubricant, it goes on wet and dries fast. Let's see how long this one holds up.



"Tri-Flow® Superior Dry Lubricant is an elite formula created for dry and dusty conditions. The drip bottle application, with a convenient straw, allows for deep penetration in hard to reach moving parts. Featuring paraffin wax and high-grade petroleum oil to allow the lube to go on wet, but then set up in a dry, 'wax-like' film so it will not attract or absorb grit and grime. Perfect for dry, dirty, dusty conditions, while still providing adequate wet weather performance. Holds up to extreme pressures and resists water wash-off. Provides incredible efficiency without attracting an excessive amount of contaminants."

Sorry, man I've never used it on my blower motor (my blower has been trouble-free since I bought the truck new). I was simply showing the other poster a dry Teflon lube since he was inquiring.

I use the Multi-lube on my motorcycle chain; best chain lube I've found for o-ring chains, as it lasts a good bit and does not attract dirt. Most dedicated motorcycle chain lubes are notorious for being tacky, attracting a ton of dirt, and ultimately forming a nasty paste w/ that dirt that ends up grinding the life out of the chain. Mult-lube does not do that. So far, I have over 12K miles on a stock DR-650 dual sport chain (it's seen rain, mud, water crossings, dirt, offroad abuse, and highway) and I've only had to adjust it twice (both times w/in the first 500 miles while the chain completed its initial stretching).

Has anyone found any water leakage on your blower motor or filter? Anyone know why or how water leaks into there?

 

Dang...my blower motor starting to make that clicking noise (35K miles). same thing happend to my Honda CRV at about 70K miles. I was unable to open up the honda crv blower motor so replaced it at a cost of $35.

So you are saying even after I change out my Tacoma blower motor, it will just happen again? On the low and second speed settings I can hear it. Any speed higher the velocity of the air hides the noise.

 

Update: over 2 months have passed and it's still quiet.

 

I tried this fix for my 2011 this afternoon. So far its quiet I hope it last. Thanks for the write up.

 

At the dealership getting the fan motor serviced now, I'll let you know how it goes.

 

Just got back from the dealership, the motor is now much more quiet.

Official service notes:

"CS blower motor makes chirping noise on low. Tech inspected concern. Tech confirmed noise coming from blower motor.

Tech replaced blower motor with new updated blower motor per TSB 0162-11. Tech re-checked blower for noise - Ok at this time."

I did this fix 5 weeks ago. I used synthetic wheel bearing grease. No chirp so far. Great fix. Took only 15 minutes.

 

Got tired of the squeak on my 2011, I after reading through some of the fixes in this thread, I got to it.

Tip for those trying to take the fan hub off (which is a must if you want to do this right), carefully drill a 3/32" hole directly above the motor shaft in the center of the fan itself. Use the smallest punch you have, and having the whole assembly braced in a vice so that the stator and shaft assembly can move freely, gently start tapping the fan hub off. Careful not to let the whole works fall and break as you make the last few taps. Worked great for me and such a small hole isn't going to effect the integrity of the fan at all.

After that ordeal, I actually found there was not enough vertical movement in the 2 sections of the motor assembly, essentially preloading these bushings creating too much friction, and thus making noise. After removing 1 shim from between the bottom portion of the shaft and end cap (the part you take off for removal), and a liberal lithium grease job, alls quiet after re-assembly.

Hopefully it stays that way.

 

Sound good. Thanks for the write up. Any Pics ?

 

I should have taken some, but I was more worried about getting it done.

 

OK, thanks 4 reply.
