LC200 A/C turns off on engine restart (5 Viewers)

[blatant]

So I went ahead and checked the cabin filter, even though I still had miles to go before needing to change, by my records.

What i found.

1. I had it on recirculate, upon opening the hatch, i could see the filter. I pulled it out. Promptly, the accordion came down. Vehicle was not on.
2. I pushed start twice, hit the recirc button to outside air, then back to recirculate quickly, a double tap, and the accordion went up.
3. The filter was extraordinarily dirty. Rather than cleaning, I ran to the dealer, shelled out 17 bucks for a new one.
4. Put the new one in and I'm all set. Back to normal operation regarding the auto button and controls etc.

So given that this just happened, out of the blue, I have nothing to add really since the cabin filter was messed with thousands of miles ago by me, and done as the manual states.

The only things different in the vehicles usual operation as of late was 100+ miles of rough forest roads over the last week and the excessive dirtiness of the filter. Maybe the crazy roads and dust coupled with all the other dusty, rough roads since last change prompted the system to act like this to indicate a filter issue/dirty filter??

Hope this helps someone in the future.

I have the same issue with my car, i have to wait around 20 seconds before i can turn the AC System back on?

Just experienced a similar issue w my ‘11 LC200. The climate settings would reset every time I got back in the vehicle. I’d have to manually reduce the temp to Lo and turn back on the fan each time I started her up - annoying in Phoenix even in February.

I did a quick thumb through the owners manual and couldn’t find anything helpful. Much of the Google search results left me equally lost.

Which brings me to yet another reason to be thankful for this community. It took me two minutes to adjust the cabin filter and now the issue is resolved.

Thank you for this thread!

Absolutely love this forum. Had the same problem thank you for the thread

Had this same issue. 2008 LC. Bought it used a year ago. It was annoying to me, but what matters more is that it annoying to my wife, which ratcheted up the annoyance level exponentially. I had checked the filter a year ago, and did not pay any attention to the Recirc/Fresh air mode buttons, so I have no idea which one was activated. In retrospect, it probably was Fresh. This time, I set it to Recirc per the manual. When I opened the access panel to the filter, I saw he accordion door and was able to flip it back (or "up" depending on how you want to look at it), and then it would flop back down. I pushed back on it with some force (not a lot), and I felt and heard it click. Then it stayed in this "up" position. I assume that is the Recirc position. Now it works the way it should. Thank you Thank you Thank you Skyak.

2017 Land Cruiser, having the same problem after cabin air filter replacement (30K)
The auto does not stay on, temp defaults to 75; and the driver temp is linked (vs separate) to the the passenger temp.

also seems the auto seat warmer doesn't stay on....maybe I have something else going on too....
just took it back to dealer; glad I found this thread; I sent this their way

Ok so this just happened to me after jiffy lube replaced the air filter.

The accordion door was down and I had to manually lift it up. I heard the snap and it is staying in the upright position and now comes back in automatically at start.

However, changing it to back to fresh air does not bring the accordion door back down. Is there a delay or did those bozos break my filter door?

Is that even something I should worry about getting fixed? How much difference can that accordion door really make?

If you heard a snap and it won't cycle between exterior air/interior circulation then sounds like you have a problem. Yes, it will cause issues with fogging.

Ok thanks for the feedback.

Apologies for my naïveté, but is the only purpose of the recirculating / straight through air buttons the raising and lowering of that accordion door?

Or another way to ask it, if the light for recirculating is on, but the accordion door is shut, am I only getting the straight through air flow? Conversely, if the straight through air light is on, but the accordion door is up, am I getting recirculated airflow?

 

[Sac Cerevisiae]

I can’t recall which is which, but you should see the filter switch as you cycle through the button. If it stays in one position then you’ve got a problem. Could be an easy fix. There are a few threads on solutions.

 

[afgman786]

Good luck getting Jiffy Lube to admit they are at fault...

 

[Lush]

Haha, luckily won’t be a problem because the door is now moving up and down as it should. Must be a delay.

I have the exact same problem on my 2010 with about 120K miles. A/C running pretty much always here in the UAE so the start-up delay plus the need to reset everything back to your preferred settings is annoying after each start. Checked the filter and recirculation door which is working fine, haven't disconnected the battery but will give that a try.
In addition, on the front passenger side the system seems "confused"; much less air emitting from all vents compared to the driver side. With the air flow directed to the middle vents, there is actually more air on the feet than from the middle. Changing air flow towards the feet reduces air to the feet but no increase happens in the middle. Have gone through the test mode of the system to no avail.
Toyota repair suggested that one of the control valves must be stuck, something that only can be fixed by swapping the entire airbox from the dashboard. Including service a US$3700 fix. Haven't pulled the trigger on that one, any good suggestions welcome.

The a/c on my 2018 LC200 was resetting to 25 degrees Celsius whenever i switched the engine off. It had just gone through a 10k PMS. I'm so glad i came upon this thread (even if its really old). The service technician who did the PMS didn't reinstall the cabin air filter properly. I did it myself and that solved the problem. Thank you!

 

[tpgrole]

I'm very grateful for this old thread. I had a hunch something was wrong when my climate control reset every time the vehicle was shut off. Found that the cabin filter wasn't even inserted properly, and the accordion door snapped back into place easily. I did have to unplug the battery to get it to reset. So happy to have the heat come on with the auto starter! Thanks!

 

[pjthompson]

Just wanted to thank y’all for this thread. Was having the same issue and found the Cabin air filter wasn’t inserted properly. Inserted the Cain air filter correctly and the problem was solved. Hope this helps someone else.

Rarely is there a “new” problem discovered on a 200 that has not already been discussed here. My 2011 LX570 just started to have this problem this week. I’m in the Chicagoland and lately it has been cold AF. So I use the remote start in the morning. However I’ve been getting in the car to find it cold because the air was defaulted to off. After reading through the thread I thought, “this is weird, no one has worked on the LX accept me for years and I haven’t touched the cabin filter.” So I went and had a look. I found a very dirty filter and a freakin walnut in it. We live out in the sticks and we have rodents. It seems a squirrel, mouse, etc. decided to stash a nut in there. I cleared it out, did the diagnostic code clear and we seem to be working A-OK now. With as sophisticated as these vehicles are with sensors I wouldn’t be surprised if there is some little infrared led and sensor in there looking for instructions so the bellows doesn’t move and break. Anyway, I’m happy to have it working and know I will go and order some new cabin filters.

Well, I think you will be okay about the cabin air filter. There are no wires or sensors that connect with that filter or the plastic tray it sits in.

First I'd say to remove your negative battery cable, attempt to start the motor. That will dump that last charge the ecu has. Wait a few minutes, connect the negative battery cable. Turn the vehicle to ACC (not starting the motor) and let the screen show you it is running through its loading process. Once loading is done, fire up the motor. And let me know what happens.

I believe this has fixed my issue. It started a few weeks ago and the dealership said there was nothing wrong. I worked through several items and eventually came to your rec of removing the neg cable etc. I’ll check it again in an hour or so but the initial dump and start proved positive. Thank you!

I was wrong. I don’t know what’s going on but nothing has solved the issue. Note: When the vehicle is started, the recirculating door cycles before finally turning on ac. I assume that’s what the delay is.

Steps taken:
Recirculating door is working great. Linkage intact.

New filter today

Battery disconnect for 4 hours

Negative pulled, attempt start, waited 10 min, replaced connection, acc until after load, started vehicle, worked great. Waited an hour and tried to start and back to delayed climate control.

Same situation here, performed all the same steps as posted previously. The door opens and closes as expected but after a given amount of time 1 to 1.5 hours of being off, all the previous settings are lost and there is a +/- 30 sec delay before any setting can be changed. It just started to happen out of the blue... not after being in the shop.
