Ventalation defaults to re-circulate

[jvangun]

I did a quick search and could not find anything related to this subject. The weather has been nice enough around here to roll the windows down and turn the A/C off. I set my controls to pull fresh air in rather than to re-circulate which is what you use for heat and A/C but every time I turn my car off and then back on it defaults back to the re-circulate option even through the A/C is off. Any ideas on why it is doing that and if I can change it? I have a 2000 Land Cruiser.

Thanks in advance.

set the temperature to 75 and it should leave it as fresh air. I ABSOLUTELY HATE the HVAC controls on these Land Cruisers. Worse on the trucks with Nav

I agree. Frustrating when you turn "Auto" off, yet the system still tries to control things. In my 2002, if the temp is set to 70 or higher, it will stay on fresh air, anything lower, it wants to switch to re-circulate and I have to manually change it back. It's always after that "why is it so stuffy and warm?" moment...

I have a non nav 2000 and this is how mine functions as well. I assume its to help the AC reach maximum cold the quickest. Don't have anything to back that up though.

That's true, if you've been in a Ford with a Max AC option, it switched to recirculate. If you pressed the recirculate button on my old Civic's AC it would immediately start blowing harder.

My non Nav 100 does the same thing. It just depends on what the temperature is set at. If I want outside air, I just leave it on 65 and turn recirculate off when it comes on. Annoying but not that big of a deal in the scheme of things.

I'm just happy to hear that there is a way around it Trying to learn all of the little intricacies of my new truck. For example, like the fact that I was trying to get the car to "chirp" when I hit the lock button twice only to find out that I had a remote start already installed. Talk about a nice surprise.

If there was a way to defeat this function - what would that be worth to you?

Is this another benefit of older ac system? My 98 is what I want. How i like it. Full manual control of recirculate. Newer Toyota systems always seem to default to recirc. Is this good feature true of all 3 knob configurations? Does the default happen only on non-3 knob design?

We are talking about 3 dial HVAC controllers.

So my 3 dial 98 ac unit does not default to recirc, but later 3 dials apparently do...When did they change the program? Know you're working on the ac retro fit. Thought this info might help...

Any info is good info. I'm unaware of any program change in the Body ECU but ther are always subtle differences.

Any other 98 owners not have the recirc behavior?

Try not setting it all the way to the lowest temperature. If you notice when you are driving and you have the temp up and it is switched to fresh air, then if you turn it all the way cold it switches to recirculate.

Figure out where it switches at and then leave it there. Might fix the issue.

I didn't reply before because I wasn't sure about the behavior of mine. I checked my '99 over the weekend and it does not default to recirculate in any mode that I tried.

Mine is a 2000 and does. Maybe 2000 was the first year of auto recirculate when the temperature is set to below ~75 degrees.

My 2000 automatically goes to recirculate when I set the temp knob at anything below 70-72.

I think Klaus is right.

Another data point would be rear air.

The auto recirc may be programmatic to that system. There were a number of updates to MY 2000. E Arlie's RA was an option.
