Fan blower motor squeaks

[MikecinGb]

I'm about 3.25 years in on my 2014...65k miles. In the last few months (it's cold in Kansas), I've started to notice an unbearable noise when I turn on the heater. It's worst at speeds of 1-2...becomes less audible at speeds 3-4 as the frequency increases.

In doing a little searching online, it seems several owners dating back to 2012 have traced it to the fan blower motor. I've tried contacting customer service. Obviously, I'm out of warranty. They told me to get it officially diagnosed, which would cost about $90...then about $350 to get it fixed.

I'm pretty disappointed in that it seems to be an older issue dating back to 2012 that was not fixed for 2014. Perhaps it just took that long to manifest itself. Either way, seems like a quality control issue, not a normal wear-and-tear issue. Anyone else had this problem and how did you fix it?

I have a 2015 hatchback and i notice the same noise. However it's only when i have the air blowing in the windshield defrost and feet/windshield defrost position. The noise goes away whenever i switch to just feet, face/feet, or face blowing.

Haven't fixed it yet as it's a little chilly out to fix it myself and my stereo is loud enough that it overpowers the noise the majority of the time lol.

Would love to know if someone has an easy fix for this though

You may have seen these threads already but just in case.

Good luck, I don't think its that common and probably cause by things falling into it.

I just replaced the blower motor in my 2012. Couldn't take the noise any longer. I think it gets worse when using heat. Bought the part on Amazon and did it myself. Hardest part of the job is cutting out the old blower motor. You could probably get away with cleaning and lubing it.

Thanks Palmaris. I believe it was this site I stumbled upon when originally searching about the issues. At one point, i'd seen a customer service rep say to contact her. Honestly, I was hoping I'd get something like that. When I called customer service and talked to dealer, I was told they had ZERO complaints about two issues and I know that's false because I'd seen many complaints online.

It's no wonder people prefer other brands of cars. Here are the issues on mine just over three years in:

Driver side door lock button stopped working (right around 32k miles...2k after warranty)
Windshield wiper fluid hose continues to disconnect
Fan blower motor is unbearable to listen to

My blower motor has the same issue.Never did it steady enough when car was on warranty.3 months after warranty expires and now a steady noise...Chevrolet denies all sorts of issues where you can see tons of complaints about things all over the place about this car.
The dealers favorite line seems to be "Unable To Replicate"..I have been extremely dissapointed in the Sonic overall and the service or lack there of by dealers and Chevrolet.

Mine was replaced as a warranty at 40k

My guys also said they couldn't get it to do it. It takes a good 10 minutes, usually highway driving, to get it going. Then it won't shut up. Time to start emailing people, I guess. Just silly to make an investment that big and have some issues that seem to date back to 2012 and then they deny ever hearing about it.

What warranty was it covered under?

2012 Sedan LT 1.8

My wife claims our 2012 sedan makes a clicking/chirping sound from the blower motor, but I can't hear it... High frequency hearing loss? What did you say dear? $73 on Rockauto, but probably a pain to get to in cold weather.

I had this problem about a month ago. It ended up being there was some rust dust on the motor causing the chirping sound. Unfortunately the new motor was expensive, but got a new one in there and it sounds good as new.

Ok cool, my 13 only has 40k on it but they denied lubing the clutch pedal under warranty. I wasn’t sure if those would be under the same category or not. Thank you!

Common issue, but I've never replaced one in any of the three Sonics I've owned. Wife claims the 2012 sedan does it, but I can't hear it.

Turn up the radio a bit, develop high frequency hearing loss, or both. Problem solved.

I had the issue on my 2012 Chevy Cruze (same engine) about a month ago. It turned out to be that when the spark plugs where replaced the tech didn’t put them in right.
