Whatever you do, DO NOT leave the recirculate on for more than 15-20 minutes. You will use up all the Oxygen in the car and DIE!!!!!

Seriously??

 

 

I came across this older post, and wanted to share a couple of things.

1. Leaving recirculate on all the time will cause water condensation to build up in the A/C system and cause mildew. Then whenever you turn on the A/C or heat, you will get a mildew odor from the vents. I had this problem with my tC and had to take it to the dealership and have them put some type of mildew killer into the A/C system, which took care of this. Apparently, Toyotas are notorious for this mildew problem, the dealership service manager told me. My Camry did the same thing and had to go back to the dealership to have the mildew killer put into the A/C sytem. Now, I hardly use recirculation on either car at all.

2. In the summertime, the air inside the car can be heated to 160 degrees or more during the day. If you are trying to cool 160 degree air, instead of the 80-90 degree ambient air. It will take the car longer to cool off inside using recirculation in the summertime.

3. Dunno if it was a joke or not, but leaving the recirculate on will NOT deplete the oxygen levels in the car and cause you to die. There is enough air leaking into the cabin to keep the oxygen levels above the minimum 19.5% oxygen your body needs for cellular respiration.

 

Holy crap thats hot!!!! See thats why 5% tint should be totally legal..

Good thought, but you will still get enough sunlight through the windshield to heat the car to 160 degrees F.

 

I am so glad you posted all that. I did not feel like typing it. This is all accurate. I thank you.

 

the 05 tc HAS a cabin filter.

 

actually no it doesn't have one from the factory. Any dealership will tell you there is a note from Toyota that says "flow restriction, no filter used". But a lot of people do put the filter in and have had no problems. Yes there is a slot for it, but the filter wasn't in it from the factory.

 

have any of yall have a mildew smell coming from your vents?

and how come my windows fog up when i have my defroster on when i try to defog my front windshield

 

i think i have used that button once since i had the car....
i dont even recall the last time i used the A/C in any of my recent cars.....

 

When I bought my 06 tC, the woman at the dealership said to turn it on one day a month or so to prevent mildew build up. Dunno if that's the "safe" number, but it did put some warning signs up in my head about mold prevention lol.

 

just doesnt make any sense to bring in the opposite temp air when ur trying to cool down/warm up unless ur defrosting

 

The earlier tC's came with the plastic cabin filter tray without the actual filter from the factory. I'm not really sure, but I also remember seeing in my owners manuel that it was not recommended to install one for '05 tC's HVAC system. Might be different for '08 & '09.
