Hey y'all,

I have a squeak coming from the passenger side dash board. The squeak only happens while the fan is on and i'm driving over any sized bumps. It also squeaks most of the time when I initially step on the gas pedal. This is strictly related to the fan or blower being on and driving over bumps. And also when I initially step on the gas pedal. The torque of the engine starting to move the car must move something in the fan or blower motor system and makes it squeak.

This is a HIGHLY annoying squeak!!! Someone please help!

I had something similar happen to me. Thought it was a leaf or something in the a/c blower motor. Had the dealership look at it and they said they got some leaves out of it and it was fine. Noise was still there but much quitter. Over the next week the noise got louder and louder. Took it back in and they looked at it again and said, "Oh, you're going to need a new blower motor. This one is going bad." $140 for the "diagnostic". Took it home, figured out how to remove the blower motor myself (underneath the passenger dash - spent a lot of time upsidedown in the passenger footwell.) Looked completely fine except it squealed when I turned it on. I sprayed some WD40 down inside the bearings and no more speak. It has been three years since I did that ONE time and still runs without a sound. The dealer gave me back the $140 after I explained to his master mechanic how I had "fixed" the blower motor.

As an aside - it just doesn't seem like anybody wants to try and fix anything anymore. Just want to "get a new part" to fix the problem. Pisses me off.

That’s the world we live in these days. Gone are the times where a tradesman would REALLY fix / repair a problem. Instead we now live in a modular world where everything is replaced with a new one.

Maybe when people go to the dealer they should be explaining they want something explicitly fixed and not replaced and see what answers they get back. Of course that’s not going to work for everything. But would be interesting to see what the dealer does. ….. or doesn’t do

Hey did your squeak only happen while the fan was on and you are driving over bumps at the same time. The bumps didn't need to be big. Just enough to shake the fan or whatever it is squeaking.

Agree totally. All those electronic modules at $400 or $800 when by replacing a mosfet or transistor for $4 plus say 1.5 hrs labour would do the trick.

Those parts are just so overpriced that some oversight should be put in place. Like telcos and their roaming fees. Robbery.

one other thing that can make a noise from within the dash is the Sat-Nav DVD drive if you SUV is equipped with that type, you might check for that. That happens to me in particular when the car is cold before it warms up.

When I had it out the more torque I put on the housing while it was running the louder it got.

And, YES, as I went over bumps it would start or get louder.

So was this blower motor or fan easy to access, you say? Do you have any link to the instructions on how to do this and check? Maybe I could try some WD40 before I threw money at it.

The blower motor is not technically difficult to get to but it is in an awkward spot. If I recall correctly - laydown face-up in the passenger footwell - you will see some screws on the panel underneath the glove box. Remove that panel and it will give you access to the blower motor. There are quite a few screws holding the blower motor in place (maybe 6 or 8 and it is tricky to get out but you can do it. (it's an even bigger pain getting it back in) Once removed it becomes obvious if something is stuck inside it or if it is the bearings making the noise. You can also reconnect the power and turn the a/c on while it is removed and check the noise again. I sprayed some WD40 down inside the bearing housing and turned it on again to check it - no more noise. And as I said, I did this a couple of years ago and have not had any more noise come from the fan.

Even though it was frustrating due to the awkward position I had to lay and all the cursing I did trying to get it back in correctly it ultimately saved me the $500 the dealer wanted to replace the entire motor.

Sorry I didn't take any photos when I did it.

So did you have to disconnect the car battery to do this repair?

It's SUPER easy to get at. If you've ever replaced your cabin air filter, it's almost that easy - there are a few more screws and you need an extension to reach a couple of them, but it literally took me 15 minutes start to finish to replace my blower motor.

There are a couple of threads on blower motor replacement around. Even going slow for the 1st time, it shouldn't take more than an hour. As others have stated, the tricky part is that you have to work on your back in the passenger footwell. A good head light (like you would use for camping) is plenty of light for the job.

how much did you have to pay for a new blower motor?

The blower motor was about $85 USD IIRC. Well worth it - now it doesn't squeak anymore and I don't have to worry about it failing. At some point, the squeak becomes a failure when the motor seizes up. I didn't want it to happen in the middle of winter, so I replaced it in September.

I'll be getting a new one within the next 2 weeks. If the blower motor fails in the meanwhile, will it mess anything else up? Or will it just mean that I want have any fan/blowing capabilities until it is fixed?

If the motor fails, it only means it won't blow air any more - means your Treg will be chilly on the inside. There are stories about a little smoke / dust when they seize up, but I wouldn't worry too much about it. If it happens, it happens - nothing you can do about it.

You can grease it. But it's a lot of work to do and then redo again in 2 weeks when you get the new one. So I'd wait it out, if possible.

I will attempt this project this week since my motor finally gave out. It started squeaking at higher speeds so I would just run it at a lower speed. That lasted through the summer but now it hardly runs at all. Thanks for the good advice on how to remove it.
