Got round to doing mine today. Took 4 hours. Not as supple as I used to be. The disc in Alphard actuator was worn out. Got avensis actuator and swapped them over . Nice and warm now. Big thanks to Gold star for video he posted. Will put pic of old disc on here.

Blimey, got your monies worth out of that component!!! LOL

Car was only imported in March. Obviously colder in Japan than I thought lol

I think I may have the same issue.  Constantly hearing a ticking sound from the actuator.  Hot and cold temperatures do work but would have to set at approx 27 degrees with higher fan speed for the hot air to come through.  I can partially see the flap actuator at the bottom of the centre console (just by the foot brake).  Can you kindly advise the steps on how to access this and replace?

Hi Waseem. If you go to the technical guides section on the forum,Goldstar has put a video link on detailing how to repair the actuator. Really helpful I couldn't have done it without seeing that first.

Thanks for this Martyn. Really useful video and top marks to Gold Star.

I'm struggling to find the actual part number based on the one I already have in my 3.0 Alphard which is 063700-8590 (based on the pic)

On eBay there are plenty of Avensis ones with part numbers ending in 8580 or 8610. Was hoping to do a swap of the whole part but not sure if I specifically need 8590.

The Alphard ones (8590)are like gold dust . Couldn't find one anywhere. Was quoted £ 279 with delivery around end of November. Decided to get the Avensis one off e bay and swap the worn part over. It was from an 06 Avensis cost me 20 quid.This is it 

I'll probably have to get an Avensis one and swap the disc over as well.

Got a quote from Toyota and they quoted £239. Didn't realise they're so expensive
