I have a high pitch whine from my passenger side blower fan inside the lower dash. Has anyone had this problem and replaced the fan themselves? The dealer wants $299.99 for the part and I can't imagine it is that hard to do. Still too cold and icey in Wisconsin to take my car apart yet.

I have that sound as well...
I just figured it was the fan and it wouldn't hurt anything. So I just leave it alone. Lol...

Blower Fan replacement

I have a high pitch whine from my passenger side blower fan inside the lower dash. Has anyone had this problem and replaced the fan themselves? The dealer wants $299.99 for the part and I can't imagine it is that hard to do. Still too cold and icey in Wisconsin to take my car apart yet.
Yes, my heater fan bearings wore out and as they did the fan would emit a similar high pitched whine,
although in my case it would only whine / chirp under mild G loads
(when accelerating / braking or turning) and only in cold weather -
it would go away in summer.
In cold weather, it would also whine continuous at specific low fan speeds,
but changing the fan speed would reduce it to the occasional chirp.
Lived with it for about three years before the bearings eventually seized,
leaving me with no fan at all.

The fan replacement is relatively easy, the whole job can be done with no tools.
Fun part is access, tight confines under the dash while lying on your back
crunched between the seat and the dash (I pulled the seat when I did it).
A younger more limber person could do this without pulling the seat,



but removing the seat made it a whole lot easier for me ;)

BTW I have Climatronic with the variable speed fan controller, Climatic should be similar.

First drop the foam heater partition by releasing the two thumbscrews and working it free.



Once that partition is out of the way, the fan is visible / accessible.

Removing the harness connector was difficult simply because
getting your fingers in the right place to release it was difficult,
I used a couple of probes to get it free.





You have to release two locking fingers, one on each side of the connector


The tabs on the control module the connector locks too ...


The Bentley shop manual said there was a screw holding it in place.
The location for the screw was obscured, I had to use an inspection mirror to see it.
When I finally got a view of the screw location, discovered the screw was not pesent in my version.
The hole for the screw was there, just outboard of the fan control module.
(Visible in the pic below on the far left).



So after slightly lifting the locking tab (sticking out on the lower right in the above picture),
it simply twisted to free from its bayonet mounting.
But, that harness bundle passing in the back of that area blocked it from simply dropping out,
it has to be worked free of the harness bundle.
(harness bundle is covered in a black wrap, visible in the second picture above, underneath the blue arrow.)

My US 2006 mk5 GTi Climatronic fan was VW pn 1K1 820 015 D





The current Climatronic replacement fan is VW pn 1K1 820 015 L.

I ended up using a $220 aftermarket Climatronic replacement fan
that the online vendor claimed was an oem Valeo unit,
but it turned out to be a cheap chinese clone. Just the same, it works fine.

VW OE replacement fan for Climatic is VW pn 1K1 819 015 E,
and is about half the price of the Climatronic fan.
An aftermarket Climatic replacement fan can be had for less than $100.

I am guessing you have Climatic, as the Climatronic fan from a dealer
cost more than the amount your dealer quoted for the whole job - oe Climatronic fan > $400.

BTW When researching the job, I ran across a few posts where others
removed the fan and lubricated the fan bearings which did eliminate the whine for them.
So you might be able to cure it for practically no parts cost.
Of course, a dealer would not do this as there is too much of a chance
it would come back again after just lubrication.
