#2 of 20 How's the A/C & heater?
Jul 21, 2005 (2:24 am)
I've owned my '96 Forerunner since new, and one of the things that's always impressed me is the "HVAC" system. The heater in that Toyota will almost burn your hands if you leave them against the vent. And the A/C has plenty of volume and is cold as can be. Does the new electric a/c blow as much volume, and is it as cold as other Toyota's?

My 1990 4 Runner does the same.
The heat is welcomed in the Winter..when it warms up the entire truck in minutes.
I still have it....for sentimental reasons...

To answer your second question.
The HH AC does a good job in maintaining an even, temperate climate, in side.
It does not 'blow you out' as does the ICE driven prior Toy Models, but I have felt comfortable manually (Non Ltd) setting the temp.
I have had occassion to redirect the vents as it has gotten cold on exposed skin when directed on it.

On the Limited edition, you can set put the temp in "Automatic" and set the thermostat. Then, the system just takes over. If it's got a lot of work to do, it'll turn the fan on high and gradually reduce it as it approaches your desired temperature setting. When it's got itself set on high it's pushing a lot of cold air your way.
To help speed the cooling effect, it puts the system on internal circulation. I tend to not like the additional fan noise in that mode, so I manually put it back to external circulation. I've owned a lot of Toyotas and this one's climate control is just as good, if not better, than the others.

I am admittedly ignorant about these things, but am curious about the following:
1. Wouldn't turning off the heater and fan shut off the A/C compressor?
2. Would you expect the A/C compressor to have such a drastic effect on mileage (below 20 MPG)??
Thanks for your thoughts.

Yes, anytime the climate control is off, depress the off button, the A/C will be off.
On a "normal" car at highway cruise it is not unusual for the A/C to account for as much as 10% of the fuel burn on a hot summer day and 5% during the winter months with the average OAT well above freezing.
In city stop and go it will be worse.
Your ICE must run for four reasons.
1. Motive force.
2. Battery charging.
3. Cabin heat.
4. Maintaining the catalyst at optimum operating temperature, ~800F.
Absent manually turning the A/C off the incoming airflow will first be chilled and then at least a portion must be reheated to maintain the cabin at or near our comfort level setpoint.
It seems to me that converting the compressor to electric drive was needless if you still have to run the ICE as an integral part of climate control, heating or cooling.
Overall it seems to me that climate control as implemented on the Highlander and Rxh will likely reduce the fuel economy more than on a normal vehicle.
#8 of 20 AC Indicator Light w/NAV
Mar 10, 2006 (10:40 am)
I just got my new HL, and I was trying to figure out the AC indicator. After I push AUTO, that button light comes on, fine that is clear, then i push the Climate button, and the screen brings up all the climate controls. The AC indicator in the touch screen has a yellow bar, I push the nav screen button and it turns blue. OK so I assume that yellow indicates that that the AC will turn on if needed, and the blue indicates that I have manually turned off the AC.
Can anyone confirm this? Is a yellow bar on (automatic), and blue bar off?

Yes, that's true. It's supposed to look like the Auto button you just mentioned. Yellow is lit (on) and blue is unlit (off). It doesn't necessarily mean "automatic" because you could have AUTO shut off but you could manually set the fan speed and turn A/C on, can't you?

I searched the manual and found where it tells you one can turn on and off the AC, but it did not say which was which. I am pretty sure you can have manual control over the AC and fans if you want. It is just too cold here in San Diego (if you can believe that), to test the AC.
