Disagree

My Ride: '01 330i, '11 535i
I've read this entire thread and am not yet certain my symptoms suggest the FSR is the culprit. The expense is rather minor so probably will replace anyway unless someone suggests otherwise.

This is a '01 330i. The HVAC console all looks and acts as normal, but I get no blower air out of the system. With fan on high, nothing. There is hardly any flow, and actually not even any fresh air at driving speeds. I do not get the erratic fan operation which immediatedly suggests the FSR is suspect. Also, when I run the temperature setting up to hot, the radiator coolant indicator comes on. I have confirmed the radiator coolant level is fine.

Any suggestions I should investigate before replacing the FSR? Is it felt the FSR is the problem?

Thanks. Patrick

its easy!

If you have a multimetre pull the blower motor cover off, turn on fan, check for 12v.

If 12v is present and fan is not moving, replace the fan.

seems very similar to my case. I replaced the FSR first, and then the fan. I think i had a mixture of problems though.

Let me know

Thanks for the reply.

So I get in my car after work to head home, and the thing is fine......the problem has disappeared, fan operated as normal. Don't know what to think now. I'll see what tomorrow brings.

That was one of my symptoms. Fan would run for a while then nothing.

Replaced the FSU this weekend. Not a picnic for me.

58 yrs old, 6'2" and about 220. Damn near froze up under there. But managed to get it done in a little over an hour. Definite PITA!

Thanks to all that posted. I'm sure this thread will live on another 7 years.

UK 323i

Got the same problem on my 1999 323i, sometimes the fan will work or it's very slow or it won't work at all.
Waiting for the new FSR to arrive in the post, but one question, my 323 is a right hand drive UK model - so is the FSR under the steering wheel side?

It appears I need to replace my FSUR as the fan speed occasionally doesn't do what I want (when it acts up it will not blow at all or very slowly even if I set the fan speed to max, but eventually it will get its act together and obey my commands) but I'm finding wide ranging prices online, from a $46 one on Amazon where a lone reviewer recommends staying away from since it died within months of installation, to a $93 Behr aftermarket from ECS Tuning (the offer a "genuine BMW" FSUR for $96). I'm not sure if the pricing of Pacific BMW has gone up the 8 years that have passed since the OP's original post in 2005 is still $77 shipped.

ECS Tuning has some very competitive pricing on most parts so I'm not sure if I should trust that ECS Tuning is offering the most reliable aftermarket FSUR or if there are just as reliable but lower cost brands from other vendors out there I should look at.

Behr and Valeo are OEM. get the Behr newer version with more prongs at Autohauz for about $60, older version is $50.

Verify the part # that will fit your car.

Thanks for the links! OEM Bimmer Parts sells the Meyle manufactured "new" style FSR, but knowing that Beyr is the OEM manufacturer, I went with Autohaus AZ.

Search and you shall find! Wow this thread was from 2005. Very helpful.

My fan just started going at 100% speed no matter what speed I set it too. It goes to full blast. Car just reached 96,000 miles today. Not bad for a 2001

Thanks everyone for you input

I'm back. Nearly two years ago I had a suspect FSR, the problem was intermittent, but then one day it "fixed" itself. My post is above. Today the blower stopped working, seems to be down for the count. I've checked the fuses and they're fine. I'm committed to replace the FSR.

I've shopped for the part and see there are 2 variations....one with 39 pins and one with 58 pins for the heat sink. AutohausAZ shows the 39 pin heat sink for models with automatic climate control. Pelican Parts shows the 58 pin as obsolete and replaced with the 39 pin part.

I suppose the 39 pin part is correct. Mine is a '01 330i.

Thughts? and thanks. Patrick
