Apparently the local oil change place doesn't know about the correct setting for the recirculate prior to removing the cabin filter. As part of the oil change they generally pull the cabin and engine air filters to try to convince you to purchase their expensive one.
After the last oil change my wife complained of traffic exhaust smells in the cabin and low and behold I checked this site and saw the problem. Luckily, nothing was broken but the lever had popped off the armature, using this guide it was a quick job to remove everything and pop the armature back on.
If the motor is no longer working you can order a new one from Sewell for $125 with the CL discount (8710630430). Please double check with a Lexus parts tech to ensure that is the correct part number.
For this certain part, is it 87106 30480 (SERVO SUB-ASSY, DAMP SERVO SUB-ASSY, DAMP)? It seems the 87106 30430 is for air mix, anyone care to verify?
I'm not sure because I haven't checked whether my servo is broken or not, it might just be the arm like you said....
Can't thank you enough for posting this how-to. Having lived with this for years, I finally decided to do something about it. I'd been quoted several prices > $1K and the cheapest I heard was $800 to fix this.
This took me 30 minutes and $6 worth of Loctite. It always takes me a lot longer to do things on my car, so 30 minutes is nothing.
Hi all, I've really enjoyed the forums and they have helped me tremendously. I too broke my fresh air damper assembly on my ISF and glued it back together. This broke also so I dove in to fix the door correctly without removing the whole blower assembly.
I ordered PART #8702030020 which came with the pivoting door and a new arm. Here is what I did.
1. Remove kick panel, knee airbag, and glovebox
2. Remove the 2 black screws that hold a duct and an electrical box. Move both to expose the broken arm on the end of the rotating door.
3. You will see 4 silver screws with the heads pointing down that hold the top half of the door housing to the bottom half. Remove.
4. You will see a 10mm bolt on the top-right half of the housing. Remove.
5. There is a Phillips screw with the head pointing to the drivers side on top of the housing. Very hard to get to, but remove this screw as well.
6. Pull apart the upper housing at the split in the middle. Be careful but the left half will move quite far. It helps to reach toward the firewall and undo a plastics clip holding the housing together.
7. Wiggle the old door out and the new door in. I pulled the left hinge out first and then the right. Take your time.
8. Install the new door arm with a click. Reassemble and test.
This took me about 45 minutes to do and cost around $35. I hope this helps someone that is handy and who doesn't want to glue their ISF back together.
Same quoted price everywhere $800 the cheapest, and others quoted over a grand. Have this issue for an entire year now, finally getting my hands on it to fix it! Found the assembly on eBay for 30 bucks, hope that fixes it!

Would you mind sharing the link to the assembly on ebay?
I may have to buy one of those too, thanks!
I recently started having an issue with this. I was driving down the road and out of nowhere I heard a weird jamming noise from behind the glovebox.
I did some research and figure it had to do with the cabin filter mechanism.
However, the cabin filter door opens and closes just fine when I cycle between recirculate and fresh air. It just makes a jamming noise once I press fresh air and the door closes all the way.
The last time the cabin air filter had been touched was a month ago when I got an oil change at Toyota.
Is it likely I have a different issue as the door seems to operate properly?
Dissected the glove box and cabin, but a different issue now?
However, after checking today, it seems that the two plastic arm that links the servo to the cabin filter door were out of sync; therefore, it caused the arms to hit each other creating the clicking sound. Here's what I did:
Removed the arm on the cabin filter door and reset it so that the arms are in sync again.
Put everything back together.
Here comes the question:
I can now change from circulation to fresh air mode with no issues and no clicking sound, BUT!!!!! I am hearing a noise that sounded like "when Bumble Bee changes from a CHEVY to a TRANSFORMER" sort of like gears working noise.
The thing does its work but I'm annoyed by the sound coming up whenever I start and shuts down the engine. I'm guessing the servo might need to be replaced?
Took my car to Jiffy Lube last week to get an oil change (I know, went there because of time ). In their efforts to up-sell me a cabin filter, they did it improperly. Removed the cabin filter without putting the A/C in recirculation .
I'm going to the dealership this morning with the Jiffy Lube manager so that Lexus can confirm that JL is at fault. The A/C Heat works only for 5-10 minutes and then it stops. I'm thinking the motor went out as well.
Like some other people have suggested, either lock the glove box or put a sticker. I'm hoping Lexus can sort it all out and JL pay for it all.
The is250 I bought last month already had the broken door pivot and made the clicking noise. I first tried to glue it back, but that only lasted a week. Yesterday I completely removed the door as outlined by cwajciec, drilled and inserted a screw along with more epoxy. The end of the screw was trimmed flush. Seems stronger than ever now. If this breaks in the future, I'll go ahead and buy a new door.
