BLOWER MOTOR ON WHEN THE ENGINE IS OFF AND KEY OUT.
 

I'm looking for some help AGAIN..I parked my 2001 x5 4.4, came back 2 hours later and the blower fan was stll running.
I located the 50 amp fuze in the glove box and unplugged it to stop the fan.
Whats up with that? Is there a sensor or some type of relay that is causing the problem??

I tried looking through all the Forums but I'm new to this site..Is there a easy way to look up what I'm looking for or do I have to keep looking at everything posted?:dunno:

Hi Fuzzy

Try changing the hedgehog mounted on the end of the blower on the drivers side, this is a common fault on most Bimmer's and when faulty causes the fan to run on and flatten the battery.

Forgot i am from England so hedgehog maybe on the other side on yours, not sure.

Good luck

The component is known as the Final Stage Resistor, sometimes by the letters FSR. It looks like a hedgehog.

There is an article on this site on how to replace it, here:

The articles, how-to's, and online references are all tabs across the top of this page. Some may only be visible to paying (Premier) members.

You can also do a search on the phrase final stage resistor or FSR, and you will find many posts. It is a common failure.

The FSR is on the right side of the vehicle, as pfs600 notes, so it is fairly easy to get to on a LHD vehicle.

Good luck.

Thanks for your help.
If this thing is a resister, is there a way to ohm it out to see for sure if is GOOD OR BAD?

If the fan is always on, or always off, or doesn't respond correctly to the fan speed selector switch, just replace it. It is a common failure point. I share your interest in diagnosing things properly before just replacing them, but this one is so common that it isn't worth it. It isn't expensive, and you can replace it yourself.

Just replace the FSR, its a bit fiddly but i did mine last week and it takes about an hour from start to finish, As has been said its a VERY common fault. You will see when you replace it that the original one has far less spines on the heat sink compared with the new one you put in, this causes them to overheat. I paid £40 for mine so in your money about $80:thumbup:

this post shows the problem

yes replaced mine. same exact symptoms. think i paid $65 for the resistor. it literally just plugs in. sure all the diy will make it clear.

I replaced mine about two months ago and now my fan stays permanently on while vehicle is on, but shuts off once I power off. Is this normal?

Easy enough job - more so on LHD cars.

Agree re not needing to check it 99.9% certain it's FSR.

Small hands useful so call on a younter relative if you struggle.

This isnt normal you should be able to control the fan by the speed selector button.

Where is this "speed selector button" located :dunno:. I have a 2002 3.0i

Maybe i didnt explain properly but its the + and - control in the center section on the air con control pannel under the display.

You did explain correctly, I mistakenly confused blower motor with aux fan. My aux fan remains on at full speed while car is on regardless of a/c unit being on or off but shuts off once vehicle is turned off

I did replace the FSR that everone thought was my problem. Guess what? It was and it does work now.
I just love this site! Thanks everone!

Hi hello
I hope someone can help me out. I installed a FSR in my car, but it was the wrong one because the blower kept on going when the car was turned off and it created a bunch of smoke after continous use. I took out the fuse and it stopped smoking. Now i just tried installing the right FSR, the wire connection that attaches to it has been burnt. Yet I was still able to connect it. Now when I went to re-insert the fuse, sparks were created and the fuse burnt. I am wondering what to do next.
Thanks

Replace all of the burnt wiring, and hope that you haven't fried any solid state controls.

Have you thought about engaging the services of a professional mechanic?

FSR electrical connector wire, what the name for this connector wire, need a new one, ALSO where can i get it.....

JCL If i engaging the services of a professional mechanic,with every little problem why would i need X5 World, this set is to help do-it yourself hers which are on this set to fix there ride cheaply without a professional Mechanic....

Wires that connect to the FSR are likely part of the vehicle wiring harness. Replacing one or more harnesses is a big job. I think it is more reasonable to replace just the burnt-out wiring with wiring of the appropriate capacity/gauge. You will also need to source connectors.

This site is to share information among enthusiasts. It is not to teach or encourage people with limited mechanical ability to do repairs that leave them worse off than when they started. Sometimes the best DIY advice is to simply not do a repair, but rather to hire somebody with the skills to do it. Brakes are a good example, as I see many suggestions to throw a set of pads in, when in reality people should understand the risks involved.

Do you know that the FSR you put in was wrong, or was it just one that you purchased from an internet site that may have been the right one, but badly assembled?

In your case, you initially decided you could change an FSR, likely based on reading all the "just do it, it is easy...." posts. You changed it with one that was not the correct version, and you fried some electrical circuits. You appear to have made the problem worse. Now you need to replace the wiring, and replace any additional electronic components that were damaged by putting the wrong FSR in. Anything that smoked is likely toasted. You have reconnected wires, and are getting sparks. You have a short circuit. Have you ever seen a vehicle that has had an electrical fire? It can burn to the ground. And you want us to diagnose which wire to replace, over the web, without ever seeing it?

If you cannot read the published wiring diagrams, determine the appropriate wire gauge, splice in new wiring, and test the circuits for continuity and short circuits, then you shouldn't be working on it. If you do continue to work on it, you should start off by purchasing a fire extinguisher in case of future misadventures.

Sorry if that sounds harsh, but what you choose to do next could cost you a lot more than you have lost already.

:iagree:100%

hello mates,

i have a question, i been searching here on these threads but i dont seem to get it or find an answer, everynite after the X is parked for more thn 7 hours, i get in, in the morning and before i even put the key in to start it i been hearing a tweaking noise behind the radio/ climate control section on the front dash.. first i thought it was my cd stock inside the cd player, but i remove it. and the radio is off and i still hear a tweaking like sound behind there... could that be my blower motor goin bad or wat.. :dunno: ur inputs well be greatly appreciated. thanks in advance

If it sounds like the cabin blower is running and the x5 is not running at the time, replace the resistor!
I replace mine and it IS now off when the X5 is off.:p:
