There are some legitimate parts dealers on EBAY, and those that you should definately "steer-clear-of".........the best way to find a good one, is to look for an EBAY Top Rated Seller with a Return Policy.

For the record, here's another successful FSU repair where there were no blower problems, but the battery was drained overnight.

The other two symptoms are erratic blower operation, and no blower operation, usually accompanied with battery drain.

The FSU solved the problem (UK vehicle).

Help


Hi everyone, Lois from Australia asking for some help for me and my busy other half.
I have been trying to help Greg (OHalf) find a part for a bmw318i 2001 E46 auto.

we were given this part no 64 11 6 920 365 a website just answer.com as the correct part no. for a final stage unit (Blower Motor resister)

I have found the thread dealing with a similar part no, but a different model,and not certain if this no 6411 6 923 204 will fit our car model. uor vin is NJ07028,

It seems that perhaps, the part has changed slightly and may be an imorovement on the old one. I would really appreciate if any of you cool guys can help clear this up for us.

and if so who in the USA shipps to Australia this part.

Hoping someone can help

Lois

Hi you have an E46 2001 can you tell me what part no. (Blower motor resoster )you ordered we are a bit confused about the correct part no to order I was given 64116920365 for our 318i vin no NJ07028 model but it seems the part has changed. The prices for parts here are through the roof for Bmw's, we will try to order from the USA I hope.


Thanks Lois and Greg Australia

Outstanding post! THANK YOU!

Wow. This is truly the best of what the internet is about.

Thank you very much to Elvis for the great pictures and description.

Thank you to Bimmerfest and all participants for maintaining such an excellent forum.

You save me hundreds of dollars -- and made me realize that I should never go to the dealer again.

This fix cost me less than $100 and 20 minutes.

THANK YOU!!

Awesome! The issue in this post matched matched the trouble I was experiencing with my 2003 X5. I ordered the part and made the repair in about 20 minutes. I'm not auto repair saavy -- in fact, have never done my own oil change or wiper blade replacement. These photos and instructions were exactly what needed.

Incredibly helpful

Accomplished this replacement yesterday on my 03 525i after several weeks of dithering. Took 30 minutes start to finish, and I am anything but mechanically savvy. Thank you!!!

I would like to thank you for the excellent description of the AC/H/V blower symptoms: from premature failure to erratic malfunction and how to repair the problem. The job aid procedure makes it clear, and better than the official repair book.
You have a special Talent and you are making really good used of that talent… the satisfaction of helping others: It does put you in another level.

Once Again thank you.

who can help?

Hi

hoping that someone can assist.

We own a bmw 318i 46E 2001 sedan
After some consultayion we have purchased a new final sage resister blower with the correct part no for this model

Have looked at the very helpful pics from Elvis on the forum dyi.

The problem now is that perhaps because the car is a right hand drive, there seems to be other obstacles in the way before getting to the remove the resister.

Here is the problem !!!

The final stage resister wont come out due to the support bracket for the fresh air/internal air flap, servo/motor.
HOW DO YOU GET THE BRACKET OUT OF THE WAY PLEASEHoping someone can help, we can send a Pic if that will help

Regards Lois ans Greg Australia

Thanks to EVERYONE!

I purchased the Resistor from Rock Auto, www.rockauto.com $38.79, for the URO Parts brand "after market" unit.

Parts came on time fit great worked great.

Thanks to all for your posts, particularly the photos, and the detailed install instructions, literally a 15 - 20 minute deal after dealing with a Multitude of Jump Starts, 2 batteries, (one under warranty that I feel bad about now, because it was probably NOT DEFECTIVE), and a full winter in storage because I was too cheep to take the car in to have someone bend me over the log to diagnose.

This is a GREAT forum I will try to contribute when I can, and hopefully everyone else will as well.

By the way in addition to the resistor assembly I also purchased FRONT UPPER controll arm assemblies (the ones that point down, most forward on the vehicle), for $28.79 each Dorman Brand, came with the nuts great fit nice looking parts. MFG. Lifetime warranty.

Dorman is an American Company that has been in the aftermarket business for many years, and distrubuted through MAJOR National Parts houses. Although I imagine that they do not manufacture the part, I feel confident that should I have a Warranty Issue I may be able to use a local distributor.

Thanks you all AGAIN.

is it blowing air of anykind (in other words, when you increase the fan speed does it blow air in a stronger fashion?)

My opinion would be that isn't your FSU, or the velocity increase of your air would not increase. Although my BMR is not the same as yours.......mine has cold & hot air adjustments on the vents on my dashboard and the doors. If the vents are set to red for winter driving then.......... they blow hot air; if set to blue, then they blow cold air.

I have to agree with stevendc, that if it is blowing any air of any temp and you can change the blower speed, changing the Staging Unit / Resistor it is not going to solve your problem with Air Temprature.

Make sure that the AC Compressor Clutch is actually engaging when you turn on the AC. Have someone turn the AC on while the hood is opened and you are outside listening, there will be a noticable click and change in engine speed, you may also notice that the AC clutch engages and disengages this is known as cycling, as the system builds pressure the system will "Cycle" in and out to conserve on fuel consumption, once up to pressure there is only so much that it can do, by "Cycling" the system cuts down on the amount of engine power that it is consuming to run the AC compressor it self.

If the Clutch does not engage at all, there could be a number of reasons for that. Air Conditioning is a sealed system which is always under some pressure. If you have a leak there are bypass switches in the system which will not allow the system to Start as to prevent damage to components. Low Pressure Switches and High Pressure Switches. It could also be as simple as a fuse.


AC on Autos is fairly simple however some very specialized equipment is required, and not many of the parts are in expensive. There are alot of independant shops that I am sure can help you. Not to mention in some states the sale and distribution of the chemicals required (Freon) is strictly regulated.

In a good functioning Automotive Air Conditioning System you should be able to get around 20 degrees "F" in temp change from the outside to the vents in the car.

Good Luck

0. Get a flashlight, a #2 Philips screwdriver + a set of 6-inch needlenose pliars
1. Move the passenger seat back & lay the backrest down as far as it will go
2. Lie on your back, hands above your head, ready to work in the foot well
3. Remove the #2 Philips screw holding the passenger left-food kick panel
4. Slide this kick panel straight back (toward the rear of the car) to unclip
5. Slide the underside of the glove box straight back (two clips, no screws)
6. Locate the FSU harness connector and put your pliars on the two "ears"
7. PUSH (this is the important part) a millimeter or less inward, & then unclip
(Note: Step 7 took me all of the Superbowl & even then I broke a clip ear!)
8. Once the FSU connector is off, push on the one FSU connector to release
9. Pull out the old FSU and measure resistance from each terminal to the aluminum fins
10. Measure the resistance of the new FSU's terminals to the aluminum fins
11. As they say, assembly is the reverse of disassembly
12. Test the A/C & air & especially listen for fans after the key is pulled out

RESISTANCE FROM TERMINAL TO ALUMINUM FINS:
#4 #5
#1 #2 #3

pin 1 OLD: 600 K ohm NEW: 11.2 ohms
pin 2 OLD: 3.02 M ohm NEW: 1.22 M ohm
pin 3 OLD: 2.219 M ohm NEW: 608 K ohm
pin 4 OLD: 2.136 M ohm NEW: 602 K ohm
pin 5 OLD: 3.05 M ohm NEW: 1.277 M ohm

Been months since I had the battery drain and ordered the new fsu from the site you recommended , what a savings . i just changed it out took a little longer than an hour. probally would have taken have that time if i was not looking at two different sites. What a wonderful feeling . the A/C works like a dream now that we are going into spring/summer. the fsu unit does not continue to have the blower going even whn the car is turned off. Thanks again your words and pics were such a help.
