Need to Replace Blower Motor ASAP!!!!!

[hsvnole]

Does anyone know of a good set of instructions to replace the blower motor? I have a 2005 e53 3.0i and haven't ordered the Bentley manual yet but want to replace the blower motor starting today and tomorrow. My only concern is the torque needed to re-install the dash and working around the airbag.

I did have the blower motor and FSR tested at the dealership and the blower motor was bad ($1,800).

You have to rip everything in the dash out, starting with the center console, its DIY'able but its a ton of work.

It's covered in the Bentley and here http://www.xoutpost.com/bmw-sav-foru...wer-motor.html

There are no torque specs for interior trim such as the dash.

I suggest waiting until you get the Bentley (can be shipped overnight for MUCH less $s then the damage caused by ripping into without direction).

Not difficult DIY, just a bunch of simple remove/replace labor (with basic tools).

Great DIY job, the part costs 1/10th the labor hr charge.

Don't believe the dealer, they want to rip you off.
In 99% of the time, it is the FSR (happened to my E39 1998 528i).

Get a new FSR from dealer ($90) and stick it in there.
Or get a good used OEM FSR on ebay for $20 and stick it in there.
Or junk yard FSR.

If you want to troubleshoot the FSR circuit, I posted info for E39 below:

Okay. Sounds like I need to wait on the Bentley manual. The instructions in the links I have found appear to skip some steps that will only lead to more frustration.

I did replace the FRS but should probably perform the jumper wire check just to be sure.

I am a little shocked that my blower motor just stopped without sounding funny or acting erratically. Changing the cabin filter and poking the Blower with a stick might also be worth a try.

- Yes, see the link for info to short the pins to supply 12V to the blower motor.
Basically a jumper wire (with inline fuse holder) to jump #2 and #5 terminals on the FSR connector.
If the fuse blows, then the blower motor is shorted out.
If the blower runs, then you are back to FSR and/or fuse controlling the blower.

- A common cause is lack of lubrication. The blower motor shaft runs on some bushings (no ball bearings). Over time, the oil dries out creating drag and seizing.

Below is info on E39, should be very similar for E53:
