Update: no fault codes as expected, so motor itself works but I think a connecting cog or whatever to the rear flap is broken. I took it in for its mot at ŠKODA and got them to look at it, they concur about what the problem is, but reckon the dash needs to come out just to get to the motor (not cheap). Is that the case? Has anyone fitted a replacement motor? Location does look pretty inaccessible.

Yeah I did take that off but I think the motor is too far back (fuse box in the way). I’ll take another look in the morning when it’s light. Also my fault code scanner is due back anytime. But if the motor is operational but just the rear cogs slipped off then I doubt it will throw up any codes

Thanks. The far one might have popped off the teeth of the motor or something. It’s having its mot tomorrow so I’ll see what the technician says

Or does one motor operate both flaps?

Also just went back in and was able to gently poke the far vent with my hand and manually open it, so I do think that motor is shot. I opened it a tiny bit so some air can come through but when recirculating air is on, it will preferentially take mostly air from the wider open flap.

I struggled to see much, but took a video of the flaps moving (starts in recirc, then fresh and back to recirc- you can hear pitch change). I could be wrong but looks like the one closest moves but the far one doesn’t- it says valeo on it. Assume the far one is the broken clean air one. Looks a right pain to get to! video is too big to upload so here is a YouTube link: Took screenshot 1 of it in recirc, screenshot 2 in fresh air (the far flap doesn’t move)

Great thanks. I’ll take a look and see if I can manually move the flap

Thanks. I’ll plug the code reader in later. if it’s that, is it an easy fix or does the whole matrix need replacing?

Thanks yes I checked the air intake as per post, and that’s clear. but the recirc to fresh air thing- is it one that switches, if so, why does it blow on recirc but not fresh? Seems like something else blocks the recirculating air when switched to fresh. Are there two actuators?

Hi all when recirculating air is selected I get good airflow, when I use fresh air, it is minimal to nil. I have replaced the cabin filter (even running with no filter makes no difference) I have checked the air intake (outside of car below windscreen) and it’s not blocked. I have tried a flap calibration (holding AC and front blower buttons), which made no difference. I noticed when I replaced the air filter with the filter cover open and had it on fresh air mode, it sucked air through where the filter cover goes, and when I put it back on, it sucked it closed like a vacuum, as it tried to get air from somewhere- until it sucked it closed it blew air when in (falsely, due to cover being open) fresh air mode. So something isn’t open/clear between the air intake and the cabin filter box. is there a separate fresh air actuator or something that opens the fresh air flap at the same time as another that closes the recirc? Rather than one that just changes from recirc to fresh? As soon as I change to fresh air, I hear some flaps move then suddenly the pitch of the fans increases (like under stress due to no air flow). if there is an actuator, is that easily accessible and fixable (moderate level of mechanic here, at best 😃)? I have an ODB2 fault code reader and will use that later but last time I ran it, it had no codes. But my wife currently has it in her car so can’t check until this evening. many thanks!

Ok so for the benefit of others I did find the intake location, On the passenger side below windscreen as Ootohere said. Photos below. just needs the cover popping off then there’s another shield with 2 torx screws to remove. it wasn’t blocked so I’ll open a new thread with a new question to avoid confusion in this one.

Yeah could try taking that off - it is between the two wiper blade motors? Plenum or something? I did find this old post but wasn't too conclusive:

Hi. I have tried searching in vain (on the car and on the internet) but cannot see where the actual fresh air for the cabin comes in. It seems it must be blocked - when I put my heater or AC on, I get good air flow for recirculated air but not fresh air, its virtually nil. I thought aah, I will change my cabin filter. In the process I tested with no filter in at all, and the flow is also near to zero, it sounds like its under huge strain when using fresh air. I just wanted to know where the air comes from in the (assume) engine bay? Or wheel arch? Any help would be appreciated.
