Hi all, I have just replaced the recirculation flap motor on my 2015 Fabia MK3. I looked all over the web to find any useful instructions and only found some for the Ibiza here which are actually pretty good, but thought I'd add a few additional comments from my own experience. The symptoms were a loud clicking from behind the passenger side dash when the recirculation button was turned on In short it can be done by removing just the glove box although it's a bit fiddly. The glovebox is retained by 6 screws. Three on the top edge (visible when you open it. One inside to the left hand side just above the bottle storage and two underneath (one left and the other right hand side). Be careful when you remove the glove box as there are three wiring connectors (glove box light, glovebox light switch and airbag passenger switch). I found the easiest option is to remove the airbag connector only, and pop out the whole light assembly from the glove box and similarly with the light switch - remove the plastic pin that attaches the damper and light switch to the door and then twist off the assembly the is like a bayonet fitting to the side of the glove box. To warn you, the light switch assembly is quite fragile (the retaining cover of mine pinged off and several small bits fell out). Once you have the glovebox off, you will find the recirculation flap motor to the left hand side of the blower assembly. It is housed in a plastic cradle retained by two silver T10 torx bolts. One on the underside of the cradle and a second one on the front vertical edge facing you . The vertical edge one is just behind the retaining bar to which the glovebox inner screw attaches. Once you've removed both of those, you can push the cradle and motor assembly to the left. It will still be held in place by a tie wrap at the upper part, but there is no need to cut this as the motor assembly can be pushed out of the cradle in-situ Next, there is a blue wiring connector on the top of the motor assembly which when you push the cradle left should become visible. Use a small screwdriver to gently push the retaining clip inwards while pushing the connector up and off the motor. Once the connector is off, you can now remove the motor assembly from the cradle. There is a plastic pin on the top left of the cradle (nearest to you) which retains the motor. You should be able to push the motor assembly to the right which will detach it from the upper part of the cradle. The assembly can then be lifted upwards to clear the lower part of the cradle. The motor assembly will have a part number like v326800390.25844 (for a non-climate controlled version). I found some original parts on the web and brand new, they look to be around £150 or more. I didn't check with the local dealer to confirm, but found a number of reproduction parts on eBay and Amazon for around £15. Clearly not sure how long these will last, but I thought it was worth a go. There are a lot of these sorts of motors around as they are used for different air/heating controls. Ensure that the one you purchase has the same large plastic gear as the one you have removed. To test and set up the position of the motor and flaps, I found the best way was to first connect the new motor to the blue connector outside of the cradle, switch on the ignition, and then press the air recirculation button, which should drive the motor to one position. Then I switched off the air recirculation button to see the motor go back to it's open (fresh air ) position. Now, having turned off the ignition, and removed the connector, I put the new motor into the cradle and refitted the blue electrical connector. Next, I positioned the two flaps. The one in the passenger door well needs to be fully closed, and the fresh air flap needs to be fully open. You can see the fresh air flap by opening the bonnet, and then removing part of the rubber seal that holds the passenger part of the scuttle in place. You can then gently lift up the scuttle and see the flap. I think the flap defaults to fully open, but it's worth double checking. Once you're happy the flaps are in the right positions, you need to reposition the cradle back into place ensuring that the new motor gear pivot aligns into the side of the air blower assembly, and that the fresh air and footwell vents mesh with the motor gear. Once in place, you should be able to refit the two T10 screws . At this point I tested that it was working properly by turning on the ignition and turning the recirculation on/off checking that both flaps moved freely to the correct positions. Once that was all done, I put back the glovebox. One final warning, by having the airbag switch disconnected, and turning on/off the ignition a few times, it will log an error and likely you will see an airbag fault come up. You'll need something like Carista, or Carly to reset the fault. I don't think it's possible to leave the glovebox in a position with the airbag switch connected without it being in the way as the wire is very short.
