I got in the car today and turned on demist, but nothing happened. I couldn't hear the fan running, so I stopped and experimented. The display showed the fan speed changing with the speed control, but still no sound of the fan running. When I turned everything else off, I could hear a faint clicking behind the dash.

I had heard something fluttering in the fan a while back, which was cured by turning it on full blast, so I wondered if it could be to do with that. I investigated the pollen filter, which is no easy thing to do on a RHD ZOE. I found a French YouTube clip which involved removing the Glove compartment, but there was no way that I was going to try that, so I got a worklight and investigated the driver's side footwell. I found what looked like the filter cover which was held in with 2 Torx (T20) screws. I removed the screws and there was the filter, but I was unable to remove it.

At That point I gave up and booked it into the dealer for tomorrow. I'll report back when I find out the cause of the problem.

Please keep us informed of the resolution.

Isn't it quite easy to get at the filter? I removed the passenger side trim panel from the lower dash by just pulling it off, its only held on with push fasteners. This was when I was routing my USB DAB unit. Usually pollen filters are the easiest thing in the world to replace so that your average servicing mechanic can do it in 5 mins before charging you for an hours labour.

What a let-down! I read all of that with eager anticipation, only to be completely deflated with the conclusion! :LOL:

I look forward to learning the resolution.

You cynic! I'm sure every garage charges 0.083 hours for this task, it's just hidden in the £80 you pay for them to "look" at your electric vehicle and think "looks okay, maybe we should put some screenwash in there so that at least the customer thinks we've done something for our £80". ;)

Yes, I hoped that it might have fixed itself when I set off to the dealer; but sadly not, so I had a very cold 15 mile drive.

For anyone interested about the pollen filter location in a RHD ZOE, it's accessible from the driver's footwell. The cover on mine had 2 screws, but the French YouTube video seems to show a cover without screws:


... and seems to be much harder to access. Either way, it requires a great deal of pulling to remove the old one and insert a new one, as the access hole is much smaller than the filter.

I got my ZOE back this afternoon and the fan is running again.

Unfortunately, it's not clear what caused the problem. The tech tried it in the dealer's car park and could see the fault, but when he got it into the workshop, the fault cleared. I suspect that he connected the CLIP tool and did a reset.

I've just had the fan problem again. As it's well out of warranty, I tried pulling F3 in the fusebox (10A, bottom right). The first attempt made no difference, so I tried again, locking the car this time and leaving it for 10 minutes, and this time it worked.

However, it's not behaving as it used to; now when I press the Auto button, the fan does not come on until I increase the fan speed; whereas before, it used to come on at a fast speed and needed to be reduced.

Sounds like either a worn out brush if it's a DC motor, or a fried controller or position sensor if it's a synchronous one. Unfortunately I have no idea what kind of motor it is and indeed, working on it is hell :-( This is not a good time to have a failed windshield fan (talking from experience, driving 900km through a cold night with 7 people in the van)

Well, it's working OK in that the fan and heater works; it's just that it's not quite behaving as it used to. If I press Auto, all the lights on the fan speed display go off; if I then turn the fan speed control, it immediately jumps to 3. I can set it wherever I want after that.

Perhaps it needs another fuse pull, with a longer wait before replacing the fuse. But for now, it's OK.

That's standard operation. Press auto and the lights go out, the car then works out speed itself (up and down) you only set the temp dial for comfort. The rest is handled by the car. Problems occur when you try to manually second guess the car by setting fan speed or where to direct the heat (pick 2 locations, screen and feet for example and then you have issues, pick all 3 and it seems to blow no where).

Yeah tbh Sandy is right

not noticed what fan speed returns to

JJ

Yup soon as you turn the fan speed knob it goes to 3 dots. That's standard too.

Autumn update? I bet there was a mandatory update recently on gbrlink store? I don't update my SD card now, not since I got an "up to date" replacement for free to fix all my problems. It didn't, and it also wasn't up to date.

When turning the speed knob, after pressing auto, it jumps to what ever "auto" was setting it to. Might be 3 dots, might be 1 dot (etc).

Thanks for all of your replies and suggestions. The consensus seems to be that the behaviour of the fan lights is normal, even though I don't remember it working that way previously. So I'll stop worrying about it.
