Ok.. here's the DIY for the cricket/electric buzz behind the dashboard (driver's side) culprit was the fan. You will need the following description and part number from the dealership: BLOWER WITH COVER PART NO. 12-14-1-437-454. Cost $70.00. It takes approx. 30 mins to change and you will need the following tools a hexagonal tool set and a phillips screw driver.

Here we go.. STEP 1: remove the plastic cover just above the pedals..

JUST A FRIENDLY REMINDER REMOVE THE PIN
COMPLETY OFF THE FASTENER..
IF U PULL THE FASTENER WITH THE PIN INSIDE IT WILL BREAK!!!

STEP 2: remove the 3 screws from the blower.. yes this is the culprit to the cricket noise!!.. which dealer could never find..
Warning! once blower is free.. it's NOT!..
DO NOT PULL ON IT!! it's not yet free from the electric connection..


STEP 3: open hood.. head out to the front of the car.. find the electric box and remove the 4 hex screws, then remove the plastic cover..

STEP 4: Where my index finger is, in the back of the box you will see the connector to the blower slide it off (after releasing the safety clip it slides down not up...) Then disconnect the blower and retrieve it from the inside..

STEP 6: get replacement, connect it.. and place everything back!!

Hope this helps and enjoy u'r cricket free car!!
Where did you buy your blower? I can't findit withthe part number? Thanks

when you look for the part number take the "-" out of the number.

Took the blower out and lubricated the shaft from both sides it with my P.T.F.E precision lubricator. Hopefully it will prolong its life for a couple of more years.

info on part numbers

FYI, it looks like part number 12-14-1-437-454 (12141437454) has been superseded.

It looks like there are two versions - one with a 3-prong connector and one with a 2 prong connector.

To check which you need, go to www.realoem.com and look up the part making sure you choose the correct year/model. From the main group, go to #12 - Engine Electrical System, then go to the Subgroup and choose 12-35 Control Unit Box.

You're looking for part #5 called the "Cover with blower".



It looks like for cars up to 2003, the correct part number is 12907571019
For cars 2003 and up, the correct part number is 12907570074

Double check with RealOEM or your local dealer to be sure.

If I get the e-box fan disconnected, do you think I can make a 4000 mile trip without any problems? I have the fuse 28 problem, if I connect the fan the fuse keeps blowing.

My car has the chirp also but goes away when I turn the fan speed up or off.
That would be the other fan right? The one out under the hood?
I guess I can unplug this blower under the hood and see if the chirp is still there.

If your noise goes away buy turning the HVAC blower up a few bumps or turn ilt off, then your HVAC blower is the problem.

4 common cricket/motor sounds in these cars are:

1. DME blower
2. HVAC main blower fan
3. HVAC controller micro fan
4. SAP air pump motor, but this thing is not really a cricket when it goes bad, more like an angry bear!

I was able to quiet my DME fan motor with a small dab of lithium grease. I took the fan all the way out, but it would be much easier to do it without taking the fan out.

Under the dashboard the fan and motor are accessible after removing the trim. The cover on the fan motor isn't screwed in ,so it just snaps off. Move the wire out of the way pop the cover off, put a small dab of lithium grease, snap the cover back on put the shield back and thats it.

Great info

this is great info, thanks to everyone who has posted! I have an intermittent screech that goes away when i turn the fan off, so i am replacing the HVAC motor this weekend. This really helped me narrow down the issue!

Anyone have a DIY link for replacing the hvac fan blower?

Read the entire thread. A lot of tips, suggestions and part numbers have come to light since the original 2006 post.
