You just saved my cars life. I was convinced the ac was gone and it would be some 2000 dollar fix. If that was the case she was gonna get shipped out to the ol BMW parking lot in the sky. I love her but shes gotta do her part too.

If she could talk Im sure she would say thank you.

Thanks for the great DIY! My FSR just went out last week and I just picked up the new one from the dealship yesterday. Cost $68.54 - that was with a CCA discount. Otherwise it was gonna be something like 100+. Happy to say that the CCA membership paid for itself....

My fan wouldn't "fireup" sometimes when it's at its middle speeds, but if i crank the fan speed up, it'll kick on all of a sudden, but if i lower it back down, it's a crapshoot if the fan will keep spinning or not. It makes a weried nose like its trying to start up, but it can't. Do i need to replace the FSR?

Sounds like the FSR to me.

In my situation, the fan speed works ok initially, then it suddenly goes to the highest setting (maximum blast) and there is nothing you can do to turn it down (aside from turning it off completely). Then, just as suddenly as it jumped to max speed, it then goes back to the initial speed I had it set on. It sporadically cycles between the set speed and the max speed for the rest of the drive. It can be really annoying when it comes on full blast and your in the middle of a call.

I'm planning on swapping out the defective resistor with the new one tomorrow. I'll let you know how it goes.

OK, swap was a success. A real pain in the arse, but a success. It's really tucked up back and to the left of the glove box, which forces you into some pretty uncomfortable positions. Some comments:

1) There were no screws holding in my old FSR, just a plastic clip (I think someone else also mentioned this before). But the clip seems to hold it in just fine, so I just clipped the new one in as well.
2) I didn't unattach the stepper motor in front of the FSR, just let it hang there by its arm (wasn't sure how to disconnect it without breaking it). But after finishing, I don't see why you would need to disconnect it anyway.

Biggest inconvenience was reattaching the glove box door (could really have used a third hand - one to press against to door, one to hold a flashlight, and one to turn the screws).

BTW, he's a pic of the old and new. Notice the cooling fin redesign - 12 to 50, and its much smaller then the old one.

Just finished replacing my Final Stage Resistor

Well i got my new final stage resistor from the dealer for about $100 because I didn't want to wait. I'm not really good with working on cars but I wanted to replace it myself. This DIY here with the pictures is great if you follow it carefully. Thank you very much for your DIY and your pictures!!! My air conditioning works perfectly now!!! [/SIZE]

Just wanted to say it worked for me too! I have a 2000 323I and while it was painful to get in, the pics and DIY was great. thanks a bunch! I can only say that will so many of us having this issue, I really think BMW should step up and consider this a recall item. Anyway, for those of you that need to do this job? My advice:

1 - take the ac tubing off first, it'll make things go a lot smoother
2 - be patient with the FSR, it's being held with a clip only so work it out gently.

thanks

My Ride: '01 325Ci Coupe
It took me about 45 minutes all together to replace it. I ordered it from Fields BMW in Olando. For my '01 325Ci it was $86 + tax, which included the BMWCCA discount. I just went to the dealer and told them I needed a Final Stage Resistor and I was on the road.

The DIY is fairly good. My only extra advice is that you need a long T20 screwdriver in order to get to the top screw. I got one (6" long) at Sears for 7 bucks.

My AC is blowing again!! Yeahh!!!

My fan is making a whistling noise on the lower speeds and it's really pissing me off. The HVAC system isn't doing anything else weird though. Someone told me though that the whistle could be the start of the FSR going? That seems a little odd to me, but I was wondering if anyone here had any experience with this? I'd really like to get this fixed.

My Ride: '01 330Ci Cosmos Blk
I just completed my FSR replacement this weekend. I got the part for 107 with BMWCCA discount from Crevier. I removed the glove box in 2 parts (tray and the surround). It seemed easier to get back together when I finished.

If you get in there and remove the 2 screwes, the vaccuum device in front of the FSR kinda swings away, then you have to push a clip at the top of the resistor housing to free it and slit it out (kinda forcefully too). After connecting the new resistor and slipping it back in, everything goes back in with little fuss.

My job took maybe 2 hours since I did not have all my tools available and I was unable to leave the door open for easier access with more light.

I have a sore shoulder but can say it is completely fixed.

Great pictures and instructions made this job easy. Nice to have my AC back again.
I was living with the crazy speeds for months, until it quit 99% of the time.
Thanks again for all of the help.

My AC just started acting up like the OP, with the variable fan speed regardless of the setting, but mine will not turn off, even when I turn the car off! I pulled the two blower fuses to get it off. I am going to get a new FSR Tuesday, but could it be anything else? Would a ac problem show up on a OBCDII scan?

Same exact problem I had. It was draining my battery. I replaced the battery before I realized it was the FSR. Good luck.

ok my turn next, i will do it over the next week or so when i can get some time, i am going to hit up BMW head office about a recall, i am sick of the problems i have had with my car.
Rear Sub Frame went. (Free after long negoatiation, but off the road for 2 months over summer )
Door seals went (Free after making a scene)
fuel pump died ( got stuck had to wait for 4 hours then charged $400 for it to be fixed)
Lower Controll Arms (needed replacing due to poor OEM ones wearing out) about, $600 i think.
Now this, wow this car is a bag of laughs.
