07 TL, non-navi. First thing in the morning, the outside air is cold (30 to 40 degress) and the car has been sitting overnight. When I start the car, the vents begin blowing cold air at me on a high setting. I typically leave the climate conrol in auto with the mode setting to the floor and dash vents. So I have to turn the system off to avoid the cold air blowing at me and then turn it back on after a few minutes when the engine has warmed sufficiently.

Maybe it seems trivial, but my 86 Toyota Supra, with auto climate control, had intelligence built into the system so that it would not start venting at me until the car had warmed sufficiently. I wonder why the Acura techies missed this.

When I asked my salesman, he said, "Well yeah, it's trying to warm the car as fast as possible." With cold air?

 

Can't say what might have changed since 05 but my 05 (non-nav) doesn't do that. It's pretty good about waiting untill the car has warmed up a bit before it ramps up the flow to the cabin. I wouldn't think they would change that behavior.

See what other 07 owners say....but I have a feeling they won't have the situation you describe.

 

If you put it on Hi it will blow no matter what the engine temp is. However if you set it to the highest actual degree setting (i think it's 85 or 86) then it won't blow until the air is warm.

 

You might try leaving it on "full" auto (i.e. don't try to tell it what vents to use) and see if that makes a difference.

 

Crashandburn said, . He is 100% right. As soon as you change any climate control settings, i.e. front defrost on or manual vent selection, the system is no longer in full auto mode and will blow air no matter what the temp is.

 

my 04 definitely does not do this. I noticed it yesterday morning that it definitely delays coming on full blast until the car has warmed up.

 

You're right, if i leave it on full auto, it doesn't behave the way I described. But I still say it's a flaw in the system. I never set the fan setting on high, and it shouldn't blow cold air on high when the setting is 72 and the ouside air is 30, full auto or not.

 

I disagree. That's why there are two different modes: full auto or manual override for the fan speed. What woudl the point of a manual override be if it didn't change anything compared to auto mode? You'd have 10 times as many people complaining about the lack of direct control over the fan speed. Acura designed it that way so no matter what the inside/outside temperature is, if the user wants full fan speed, he or she should be able to get full fan speed.

 

I would agree if I had the fan set on high. But, as I said, I did not. The only thing I changed was the mode setting so that it vented thru the floor and dash vents. The system set the fan speed on high all by itself.

 

hello? is this thing on? if you change the MODE of the hvac system, it is no longer AUTO. What would be the point of AUTO if you manually change the mode? Auto would just control the fan speed? How does that make sense?

 

I wouldn't call it a flaw -- the system is probably doing exactly what the designers intended. But I would agree with TL-k100guy that it was a strange design decision. If the system is in full auto and you manually change the vent mode, the system is no longer in full auto but it is also NOT in a fully manual mode of operation (the system still controls the fan speed automatically). So there doesn't seem to be any good reason why in the situation described in the OP, the system shouldn't continue to wait for the coolant to heat before ramping up the fan, just as it does in full auto. Especially since the operator can still take back manual control of the fan speed at any time.

I would hate to be responsible for designing the user interface for vehicle systems like HVAC and radio. Everybody has a different opinion about what's the best and most logical way to set up the system so no matter how you do it, it's still going to feel wrong to some people.
