The higher I turn up my fan, the louder this low, powerful hummmmmm gets. On low it is barely noticeable.

It works fine on all levels though, and blows hard.

Sounds almost as if there is a blockage as I can imagine the fan motor could sound this powerful. It is loud throughout the whole dash.

Anyone else?

63,000 miles on my 08.

 

Check your cabin air filter, it may be blocked and causing a vibration or you may have sucked in some debris. Worst case scenario is a blower motor starting to pack it in, but check the cabin filter first, you may be surprised what these things can suck in. Our '06 somehow inhaled some long pine needles and it was making the classic "burned up fan motor" noise, changed the filter and cleaned out the needles...all is quiet like it should be.

 

Well, thie cabin filter was due and I had high hopes... Alas, the noise is still there.

I fear after only 3 years and 60,000 miles, the Red Sled may have a date with a new blower.

Anyone done one before? It's under the passenger side dash, correct?

 

Oh, here's a pic of a Seattle cabin filter after one year: http://t.co/bUwrvmO

 

Ick! Yeah that's about what they look like here in the Charlotte area too, kind of amazing what it catches and what you'd be breathing in if it wasn't there.

Here's a link on a blower motor replacement, its a slightly involved procedure but if you're handy with tools and mechanically apt, it looks like its only about a 7 on the PIA scale.

Haha, I'm handy with the tools... But what do you consider a 10?? Hahah

Or a 5 for that matter! I can see the sucker behind the glove box, looks easier but doesn't everything? :)

Thanks for the link, I'll peruse!

 

Lets see, a 10 would be my current project. Converting a '61 Corvair Greenbrier van into a turbocharged Corvair Greenbrier van...something even Chevy wasn't crazy enough to attempt.

 

And a blower is a 7??? Looks like a 4-5 on my scale, including your project which I'd never take on alone!!

Pics somewhere? Sounds cool! I have yet to attain toy car age... Getting there though!

 

Its a 7 on my scale because of my bad back, once you break your back, the allure of being upside down under a dashboard losses all of its appeal.

Here's a pic of the engine that is in the van now, its a 180 hp Corvair Corsa Turbo engine that I stripped down and had bored .30 over, that along with a billet stroker crankshaft bumped the engine from 164 cubic inches to 198 cubic inches(3.2L for you metric folks). The turbo is a unit made by Rajay for Corvair retrofits, its blowing into two Rochester RV-X carbs with 10 pounds of boost. The two large chrome tubes in the pic that lead off to the right are going into a modified Saab intercooler located in the right rear wheel well, its also running an electronic boost controller with an Air Research waste gate. All this adds up to 292 hp on the dyno, its quite the step up from the 140 cubic inch 95 horsepower engine that I pulled out of the van. Now its not done enough to drive for more than quick test hops, the additional power is overwhelming the rear suspension and giving me some headaches.

Still have lots to do, like fabricating a new engine cover, converting the rear suspension to one from a 1965 Corvair, upgrading to disc brakes all around, and a few dozen other things.

 

First off, that is truly bad ass! Thanks for the pics.

As for the back, I've never broken mine, but I can sympathize a little. In 1999 I was stopped in gridlock in my truck and a dumb truck with a second trailer (both full of cement) rear-ended me.

He was doing 55 and on acid. I had many injuries of course, but the one that stuck is my lowest three discs bursting.

As you well know, that part of your body doesn't regenerate ... So I'm also wary of anything low, going "inverted" as one does in the dash board scenario you described, etc.

Love the pic, glad you've kept moving, it took me a few years to fully make my come back but I fully appreciate that it can go either way, I've seen people fall into the void after suffering the injuries you have.

Thanks for the tips and continued luck with your project. I almost bought a Corvair convertible about 15 years ago, red with tan top for 3400. 4-speed I think.

I should have.
