The arm that connects my ac blend servo to the door is damaged, so the blend door does not move when I switch between fresh air and recirculated air. The servo is fine. Does anyone know if there's an easy way of repairing this or which part I should order? In the pictures you can see that the piece thay connects the servo to the blend door is missing. the snall nub at the top that has a jagged edge is broken. The white arm with the ring on it should have a piece connected to it which then connects to the nub.
here is a better angle.

I just had my mechanic replace the door/AC filter assembly on my 2008 GS350... not sure if its the same part for your IS but this fix was a godsend for me. No more rattling noise, instant hot air, keeping smelly dust out of
cabin, etc., etc.

I think I found the part. Can anyone confirm?

wow thanks, that link was very useful. I need the part that's part of 87020A. Seems like I have to replace the whole thing.

in case anyone else is doing this repair.

Not sure if this link is as useful as it used to be now that photobucket has killed the pictures, but it's still the most comprehensive one on the site for this problem: https://www.clublexus.com/forums/is-...to-circ-3.html
