HARDROCK said:While not at hot here in L.A., I did have the same problem until I learned how to work the rear air-conditioner. My X cools MUCH faster when I remember to turn on the back air conditioner by pressing the the "rear manual" button, with the rear fan on "high" and the temp on max "cold". I didn't realize the X has two separate air-conditioner compressors and the default when you start the truck is for the rear system to always be off. (also why you will sometimes find two puddles under the X when parked and air-conditioners had been on).
Your answer wasn't necessarily wrong. Depending on what you've got the temp set to, using the rear AC manually @ max fan and max cool could be colder than the fronts.HARDROCK said:I guess I've never be a "Super Senior Member" giving such wrong information as I did...
Separate or not, TRY turning on the rear second half of the one and only same overall air conditioner system and see it it helps your problem.
Set desired temp, press full auto, press RECIRC. Everything will be automatic EXCEPT recirc as you've now set it. I think.thomas said:I have no problem with the AC. However, I do have
some issue about the control. I would like to use
the full auto to keep the temperature. But when
the temperature reach to the setting level, it automatively
set the recycle back to use the outside air. When outside
temperature reach 100s, I think it is waste to use
outside and I dn't want to turn on the AC always On
by turn off the full auto. Does anyone know how to
set recycle with full auto setting?
Actually that's a good point as the front system will mix hot/cold in accord with the temperature set on semi-auto when the rear unit is enabled. However, if the front system is set to 60 degrees in full auto or semi-auto, the system runs at full cooling and does not regulate the interior temperature. (See 2003 owner's manual p. 136) Under that operating condition, I don't know that using the rear would make any difference as the A/C system's cooling capability would then be maxed out. I'll give it a try tomorrow. It's supposed to be a hot weekend (temperature--not social life).TheWorm said:Your answer wasn't necessarily wrong.

What is the humidity there? I believe it is a factor. If it is low, it'll seem like the ac is low on freon and isn't cooling as much as it should. Whereas when it is 90%+, the ac turns the inside into a meat freezer within minutes. Just my experience....lewjdw said:My air conditioner doesn't seem as cold as it I think it should be. Granted, I live in Phoenix where it hit 117 this week but I don't think my MDX cools as well as my other 3 (non Acura) vehicles do. Anyone else whining about this?

That's how it's supposed to work. If you press ANYTHING after it's in FULL AUTO, the display will change to just AUTO, meaning everything except what you've just pressed will still be in AUTO mode.thomas said:
It maybe a problem with my car. I try the sequence as you described. However, when I press RECIRC, the full auto shift
to auto only automatively. And someone mentioned before
that with auto and RECIRC, the AC is always ON instead of ON

.....that the A/C in the "X" does take a while to cool. However, once it gets going, it does make the interior nice and ICE-COLD, but I haven't yet had a chance to try it in outside temps over 85. It probably has something to do with the fact that it has to cool such a large interior area!frostyra said:........... but I think the unit cools relatively slowly; maybe I'll remember to have the dealer check it next time I'm in for service.
I cannot address the 01 or 02 model year. However as for the 03, quoting the owner's manual at page 143:frostyra said:
Unless there's a BIG difference between your X and my '01 X, the rear unit runs on automatic, just like the front does, UNLESS you press the "rear manual" button; then the rear unit runs at the speed, temp, and air direction that is set on the rear controls. Thus, you're not "turning on" the rear unit, you're just shifting it from automatic to manual......
Same as on the '01-'02 models. If that button is NOT pushed, the rear A/C functions automatically, following the same settings that the front A/C is using (if you don't believe me, stick your hand back there and feel what it's doing). If it IS pushed, the rear A/C follows the control settings of the rear passenger control panel. Either way, it IS an A/C, and it IS working.norcalchuck said:

"To enable the rear A/C passenger control panel, press the RR A/C Manual button on the control panel. The light in the button will come on."
You must enable the rear passenger controls in order for them to control the rear temperature, fan speed, and air-outlet choice. You do NOT have to enable the rear passenger controls in order for the rear A/C to work -- if the front A/C is working, the rear A/C is working. So the RR A/C Manual button doesn't turn the rear A/C on or off, it just chooses between having the rear A/C function as the front A/C does, or giving it its own separate A/C controls. That button only enables the rear controls, not the rear A/C. Honest!Quoting also from page 143:
"When the system is in FULL AUTO, the rear A/C passenger control panel cannot be used. The system will cycle on and off automatically to bring the interior to the set temperature."
So in summary, you must enable the rear passenger controls (at least as to the 03).
