The A/C works the same way, nice that it doesn't blow 160 degree air at you, very "civilized"!

On the way there
Along these same lines, my auto gets too hot at first and then settles down and does a good job controlling the temp. In the summer it works normally. My normal routine is to let the cabin heat up, then turn down the automatic control, then turn it back to the normal setting after 10-15 minutes. ?Dirty sensor? Otherwise I like it, and my wife liked it enough that it was a "must have" option when she was shopping for a new car.
To hijack this thread even more, the climate control in her '04 Sienna is much, much better than in the Cruiser, so I think Toyota has been doing their homework on this item.

mine does the same, seams to overshoot hot then after it figures it out goes to cold, I am hoping it was the dirty sensor.
The CC in my 97 LX450 sucks, its either HOT or COLD. I plan on cleaning the unit, specifically the thermosat.
My question would be if it ever worked properly in the first place. If so, has anyone priced a new one?
Has anyone looked into using different components while keeping the same controls?

seems Toyota relized the auto CC sucked in the 80's! the 100 series can be completely manualy controlled if need be.......thankfully 
However I must say the 100's auto CC works great.......so far
yes moms 97 auto CC in her 40th sucks the big one, I think Toyota spent $3K trying to make it work right when under warantee

The climate control system in the 80 series works quite well actually. I think alot of people don't like these systems because of ignorance. Alot of people slide the temp way up on cold mornings because they want heat right then slide it down when it gets to hot so the the system reads that it is way too hot and tries to compensate by releasing colder air. People don't realize if you just leave it at say 75 it may take a few minutes longer to warm up the cabin but the cabin will stay the perfect temp the whole time. The less you touch it the better that is why it is AUTOMATIC. let it do all the thinking just set it at the temp you eventually want it to be. These systems are actually very efficient and for those of you that think its screwed up that the ac is on when you have it set for hot temps thats how any auto climate is. The air runs through the dryer with the ac on thus preventing the fogging up of the windows. Most of you probably already knew this I just had to state this for those who didn't because it is really annoying to hear people complain about things when they are ignorant to the way it works.
I agree that the auto cc is made to a set and forget system. Though I really hate that the system resets to recirculate and it does it on anything under 75*, just annoying to change it back to fresh.
It's interesting to know that a manual unit will plug in and work. HOWEVER an auto cc WILL NOT work in place of a manual unit, even if it is switched to manual mode.

Well except for the fact that most the time when the cc and ac is on and set to warmer air in the winter the engine does not run that much hotter hence its winter so there really isn't a waste of gas as compared to if you had the ac on in the summer
I'm going to bump this old thread with a question. I have a '97 with the climate control system. I want to pull the unit and switch it to manual as discussed here. In another thread (here) the first post mentions that when he did this it disabled the LED for the recirculate switch. Has anyone else had this issue? I haven't read any other threads that mention that.
EDIT - to answer my own question, I flipped the switch to manual and it does disable the light on the recirculate switch. The unit functions as a manual unit but you will have to put up with the non-functional light.

Sorry to bump an old thread ...but it may be better than starting a new thread.
I have a 1997 LC with automatic climate control. And ...I may have a bad A/C System Amplifier.
The A/C System Amplifier (88650-60212) located under the dash over the gas pedal area appears to be unique to the LC80 (& LX 450s) that have automatic climate control. ...Correct ?
Will switching from automatic to manual mode by using the switch on the back of the control button module bypass this amplifier ? (and save me the repair/replacement costs for the amplifier) Or, is it still a necessary part of the system ?
Thanks !

Re-bump...
People say that switching from "A" to "M" solves the problem. I tried that and it didn't work. I removed the A/C System Amplifier and gave it a good look and it looks pristine. Something else might be going on, but symptoms also point to the amplifier.

So we meet again.
Except for a bit of fine dust, my amp looked pretty nice ...but when we opened the board (it's 2 boards connected and folded/stacked) we noticed just one one small drop of dirty water on the corner of one of the boards. We did a cleanup of the whole amp and connectors with circuit cleaner ...and it worked !!!! So, I suggest you not give up on the auto amp without cleaning and reinstalling it first.
My symptoms/problems included: AUTO, AC, and CIRC/RECIRC buttons totally nonfunctional ....no lights either; no blower ...the lights worked on the buttons though; but, all of the vent controls all worked (I could hear the vent doors moving as I pressed each one) ...and the vent button lights all worked.
So, if you have the same (or similar) symptoms, the problem is probably is associated with the auto amp. And, it may just need a clean-up.
Also ...there is another HVAC related amp located behind the glove box ...though I have not yet read of anyone having a problem with that one.
It's curious that the AUTO/MAN button on the back of the control box does nothing. ...Then, what was it's intended purpose ??? ...Or, what else has to be done to make it functional ??? It must have been put there for a purpose. ...Or maybe (and I kinda doubt this) your problem is not with the automatic components of the system (relay, fuse, wiring, etc.) so switching to manual doesn't help anything.
Anyhow ...I wish you the best of luck in getting this problem resolved quickly.

I'll take a closer look later, only had a little time today. My symptoms are identical to what you described. It happened all of a sudden yesterday, that's the weird part...
Still looking into it.

OK I took a VERY close look at the contents of that little box. There was a tiny bit of oxidation around one or two resistors. And some part I couldn't identify. I cleaned everything off with IPA, a cheap paintbrush and some Qtips.
Sweet Fing Jesus I have that sweet annoying auto A/C function back again...

Ouch "I hate when that happens!"
I'm glad an auto amp cleanup worked for the both of us.
I'd still like to know if the auto system can be switched to manual ..in case the auto amp (or other auto climate system component) decides to quit on me in the future.
