Hey guys

Which blend motor would it be if I'm not getting full flow of air from the demist vents.

I'm getting air through face vents at same time as demist vents.

Thanks

Distribution motor, top one on the RHS accessible through the hole where the instrument cluster lives. It's either jamming part way through the travel or needs calibrating. Have you got the book showing on the HEVAC?

The easiest one I guess. No book symbol. Had one once in a blue moon.
I have a feeling its sticking inside.

If it was sticking I'd expect to see the book as it wouldn't be able to travel over the full range when it does it's self test. If it has been calibrated with it unable to manage full travel, it will think everything is fine even though it isn't moving all the way.

Gotcha.
It used to work.
Not sure how I'll check it as instruments will be out to look lol.
I don't have a nano either :(

If you have the instrument panel surround out and the instruments unscrewed, you can move it over enough to see what the distribution motor is doing. The Ascot suddenly started showing the book and Nano told me that was the distribution motor. Had a look and found it was tight at one end of the travel. Not feeling like pulling the dash out at that particular moment, I gave the spindle a squirt of silicone spray where it enters the heater box, worked it back and forth a few times, put the motor back on and it's worked perfectly ever since.

By bending the ducting out of the way, it's only thin and bends fairly easily.

i used a small screw driver , the screws are reasonably loose, to put them back i taped them to the screw driver.

I used a neodymium magnet on the screwdriver shaft.

Right, I revisited this today and had a closer look at whats happening.
It looks like the motor is stopping about in the correct places according to a video i found. It moves smoothly.
I'm gussing that the motor was replaced "recently" as the screws holding the top one in are different and it looks fairly new.
Probably not been calibrated though.

I dont have a nanocom to check though :(

The blend motors will eventually recalibrate, but i think it's after 500 ignition cycles !!

Yikes, that's about 8 months using it twice a day.

If you're passing Swindon at all then let me know and I can hook it up to my Nanocom
