Is running your day-lights every time you drive use up your fuel?
#3 of 5 Air Recirculation Q. by foxyesq Jun 12, 2007 (6:55 am)
I have a 2005 Ltd. V8 (duel climate control). When I first turn on the A/c, after the car has been in the hot sun all day, the system automatically recirculates the hot interior air. When the inside temperature finally cools, the system automatically switches to allow “fresh” but hot outside air into the car. Wouldn’t it make more sense to pull fresh air in when the car is hot and to recirculate the cool air? I notice that it is considerably cooler, less humid and more refreshing if I manually change this and have the cool air recirculated. Does anyone know why Toyota (and manufacturers) set up the climate control systems this way? Am I missing something?   Thanks. Replies to this message: md4runnerman (Jul 01, 2007 6:06 pm)

Replying to: foxyesq (Jun 12, 2007 6:55 am) Well the thinking is that vehicles actually cool faster when the air is in the recirculate mode, despite what you may be leading up to in your discussion. I have read it in the owners manuals too, for maximum cooling, turn on the AC (duh) and press the recirculate button. Seems to work for me that way in all the vehicles I have owned. Once most of the cooling is achieved, it is OK then to open it up to outside air, which tends to be warmer.

Replying to: pattoy (Apr 07, 2007 5:52 pm) Hi, Did anyone have any suggested solutions for this issue? I have the exact same a/c problem on my 2004 SR5 V6, though I haven't noticed the RPM dropping yet. The dealer took the dash apart to see if there was a blockage but nothing. They have called Toyota help twice and don't have an answer.
