Hi friends,

I have a 2007 9-3 2.0T w/manual transmission w/about 82k miles on it. Started the car this morning to let it warm up for 5-10 mins prior to driving, came back and noticed it wasn't warm, thereafter noticed that the blower motor was not working at any fan speed settings. While driving, I do notice that the warm air is passing thru the vents so I'm guessing the heater is probably working, just not the fan/blower motor.

I checked the big 40A F23 fuse in the front interior fuse box, it seems to be ok. Any thoughts on what the issue may be, either a) the blower motor itself, b) the blower motor control unit or c) something else? Anything else I should be checking for?

Some additional info; car has been mostly in the garage for the past 6+ months, driven 3-4 times per week, rarely driven in rain (I know water can get past the filter and into the motor...but don't think that is the case) and also, the fan never made any weird noises prior to failure.

Update 4 hours later: Took the car for a drive, fan was still not working, but suddenly, about 10 mins later whilst driving, fan started working again as usual, no odd noises or anything, both heating and cooling/AC is working fine. Perhaps its the fan/blower resistor (pic #1 below) or blower regulator (pic #2 below) acting up and is about to give up soon?

Thanks!

Pretty common I believe. Were there any noises from the fan prior to this? Any odd behaviour like the fan speeding up/slowing down randomly?

Have a look at this videos.

Mine was starting to squeal and I resealed the filter housing and sprayed the top of the motor/fan which seems to have done the trick for now but if yours isn't a fuse then I think you may have to pull the motor.

Hi Rich,

Thank you for this, funny, I was just watching these vids on youtube prior to seeing your message

Just updated my initial post with the following: car has been mostly in the garage for the past 6+ months, driven 3-4 times per week, rarely driven in rain (I know water can get past the filter and into the motor...but don't think that is the case) and also, the fan never made any weird noises prior to failure.

Nor did I notice fan speed going up and down prior to failure, went from operating as usual without any warning to just dead.

If it's the motor (usually is) I can confirm this one works and a decent price.

more than likely the guides which hold the brushes in place have got some corrosion on them & not allowing them to slide up to the commutator when wear is taking place..end result no power to motor..

Hi there, thank you for this. So if what you're saying is correct, what part would I need to replace then to remedy the issue? I'm guessing you're referring to the brushes inside the motor, thus the blower (motor+fan+housing) needs to be replaced?

Someone put a non-oem blower in my car. I ended up having to do the job again. I wouldn't put anything in except a Valeo unit. You don't want to do the job twice.
