    No reported problems on the dash or anything else playing up. I turn the heater on and no matter what setting I put it on, no air is blown through the fans whatsoever. Any ideas? Do these cars have heater/AC ECU's?

    Your final stage resistor most likely is dead. Often call the FSU. Buy a Behr/Hella from eBay, don't buy any other brand.

    Not a hard job to do, the fsr or hedgehog is up behind the dash, you can get to it from the drivers foot well, two torcx bolts, one is easy to find the other is up out of sight,

    Hi, just out of interest, can you hear the motor for the blower working, if the motor isn't working then you'll be looking at the fsr, if you can hear the motor running but no air is coming out, try taking out your cabin filter and see what happens

    Well I'm still trying to replace this after 3 days of trying. I cannot get to the top screw no matter what I do, I've bought new tools, but to no avail. Tomorrow I will be buying an even shorter T20 torx screwdriver and hoping it works, because if it doesn't, there may well be a burning lump of Clubsport on my driveway! lol

    Out of curiousity, my daughters 316 E46 heater does all sorts of weird things, stays on after the ignition is off, doesn't turn off when you tell it to, randomly decides to start blowing harder for no apparent reason, etc. could these also be symptoms of the FSR/Hedgehog? Or is it likely to be something else causing the fault on her car? If it's the Hedgehog then at least once I have a tool capable of removing the top screw I can just get it done, otherwise I need to try and figure out why it does that in her car.

    WOOT! Finally got this replaced! Had to buy about £60 worth of tools before I finally got the right one, then, as the screw came out, that became too long, so had to switch to a driver set I bought the other day, which was too fat to get down the channel originally, but was just perfect once the screw was out a few mill and the stepper motor assembly was moveable.

    Any thoughts on my daughters one yet? Like I said before, it comes on when it feels like it, try to turn it off and it might eventually turn off, goes up and down on the fans intermittently all on it's own..... is this also an FSR problem or is this something else?
