Interior & ExteriorDiscussions about the interior, and exterior of your vehicle.
This is a discussion thread titled "Man, this A/C really does...", within the Interior & Exterior forum, part of the Technical & Vehicle Assistance Forums category.
The Tundra is my first new car with the new R134a refrig. and I miss my 4Runner's R-12 system. That thing made you feel like you were in a freezer. This Tundra makes me fee like I'm in a small, portable frigerator, with the door open! And for a such a small interior (vs the 4Runner's larger interior space), you'd think it would cool a lot better, but it isn't the case at all.
R134a works OK if the system is made slightly bigger.
Last summer some folks found that their heater valve, behind the engine on the firewall, wasn't closing fully. It only took a small adjustment of the control cable.
I'd say that something is with your A/C is wrong like KLS said. My A/C kicks A$$. I've gone to the desert in July where outside temp was well over 100 and it was like an icebox in the truck. Did a little romping around Anza-Borrego right after I bought it to "test it out" if you know what I mean!
My dealer calls it the 3-second A/C because in just about 3 seconds it already freezing cold air coming out of the vents...and I have to agree.

I often carry a windbreaker in the truck, just to keep my arms from freezing as I'm driving. Must look kinda funny to the other Houstonians.... almost a hundred degrees out and there's this guy driving with a jacket on!
I put a thermometer in mine and it gets down too 40-degrees on the highway and 45 in town. It also cools my cabin down just fine. It's the best AC I have ever had!
I find that the cooling seems OK in my truck, but that fan is real weak. The PreRunner I have get's super cold on low, the Tundra needs to be on the 3rd highest to equal what the Taco gets on Low.
Anyone else notice this??

I agree. If you put it on recirc it's better, but it's still not ice box cold like I'm used to on the older cars.
I just drover my pathfinder with it's r-12 refrigerant and that is ice box cold. You have to move your hands around on the steering wheel so that your knuckels don't get sore from the cold.
Maybe I need to make sure that the heat isn't stuck slightly on. It's pretty cold. But not nearly as cold as an r-12 system. It's cool, but I can only get it so cold. Putting a thermometer in there is a pretty good idea. Then it's not subjective.
I'll have to try to test ride an new tundra to see if it ride any better with the air on. I wouldn't think mine is defective, but it might be.
I just know it's not nearly as cold as my pathfinder is.
If you turn on your air to recirculate, it will cool down faster. I have found that after the truck is hot, the intake for the fresh air will be like the heater is on if you just turn on the vent with the fan on and no AC, so recirculate the cool air for a while. My wife had an older Honda Prelude with a huge black dash and if you ever had the fan on with the fresh air it felt like the heater was on. In fact, you almost had to drive all the time with the AC on, it was like a huge solar pannel. All the air was being heated by the engine compartment and the black dash. I have found the tundra to be very cold, even at start up if you leave the recirculate on to let the system cool down than let in the fresh air.
My A/C in my 2001 Tundra works great. It gets so cold condensation forms on the shift lever. Best A/C of any vehicle I've ever owned. It was 100 today in Sacramento, and it was blowing ice cold with no complaints from me.

That's where i reside. I work at McClellan Park, and really when I went out for lunch and came home, the A/C wasn't cold like a freezer like in my old 4Runner. Yes, I know that re-circulating air is best for blowing the coolest air, but still it wasn't cold enough, just cool air like from a refrigerator, which to me is un-impressive
I live in Mass. I agree mine is not that cold. Maybee my heater control is stuck too. It was'nt that hot today but hot enough for a/c. I was comfortable but not freezing like im used to in my previous cars!

Okay, let get rid of the subjective nature. Ice box cold, cold, cool are all subjective. Let's benchmark.
Yesterday, it was 80 to 85 degrees here and the coldest I could get my cab with full on air conditioning with the recirculation on was 65 degrees when it was 85 and 60 degrees later in the afternoon when it dropped down to 80 degrees.
That was measured with refrigerator thermomer which seems to be pretty accurate as I benchmarked it against my heating thermostat in my home.
Leaving the air on 4 is obnoxiously high, but that's as cold as I can get it.
Can anyone else on here benchmark what their performance is in a similar manner?
If I can only get a 20 degree drop at 80, then that means that at 100 it's going to be 80 degrees in the vehicle. That is uncomfortably hot. Not as bad as 100, but still too hot.
Now, it might be that at 100 the efficiency increases so I can get a 25 degree drop, but usually it's the other way around. Most likely due to ineffeciencies of the heat sink, I'll only get a 15 degree drop. So that means the vehicle will be 85 on a hundred degree day.
I don't feel 80 or 85 on a 100 degree day is cool at all.
Sixty or 65 on an 80 degree day is okay, but that's only when on max cooling and that's still not that acceptable. I'd rather leave it on 2 at the max. Maybe 3. 4 is too much.
On low on my pathfinder with recirc on it is much, much colder even on 1.
In fact you really can't leave it on anything higher than 2. It's too cold. On 4, well, you get ice cream headache if the air is blowing on your neck. It's uncomfortably cold when you go past half way unless it's really, really hot.
My tundra with half the air volume doesn't even compare. Maybe my heat is on a little like some others on here. I'll have to try it on max cool recirc, then shut off the air and see if warm air comes out.
A good benchmark would be atlest 20 degrees colder than the outside temp. Your unit can blow air as cold as 40 to 45 degrees but it should be within the 20 degree seperation. This is what the Air conditioning shop said when the retrofited one of my other cars to 134A. The new 134a freon works different the the r12 and will not be able to get as cold.

It was 80-degrees out that day I believe. I measured it with a thermometer.
Man, this A/C really does...
