Hi all,

I recently purchased a '14 ELR and I am experiencing the following......

If air (hot or cold) is set to 'Auto' with Max speed .... a lot air is felt from the vents.
If air (hot or cold) is set to 'Auto' with ECO speed .... moderate air is felt from the vents.
If air (hot or cold) is set to 'Auto' with Min speed .... air is felt exactly the same as Max.

Is Max and Min air pushed from the vents the same?

I also wanted to point out the 'Climate Power' for Max is 40%, Eco is 24%, Mix in 14% .... at 14% it's blowing the same air as Max (40%). Of course depending on the temperate setting, sometimes Max is 100%, Eco is 60%, and Min is at 20%.

I thank all for viewing and replying...hopefully someone can confirm this for me.

Cheers!

Having it set to auto wouldn't surprise me that a noticeable difference doesn't occur since the fan will blow at the required speed to "auto" adjust the cabin to the desired temp. The reason you notice a slight decrease only in ECO is because that's their "power save" setting. Not too familiar with the ELR climate settings but I would hazard to guess that the "min" setting refers more to the power allowed to operate the A/C compressor and heater module rather than the fan itself although I'm sure someone else could probably chime in with a correction on that. If it's anything similar to the Volt climate screen, rather than a "min" setting, we are graced with a button that says "fan only" and does run the blower at the same speed that max setting would run but without turning on the heater or A/C. The power meter also reads about the same when in fan only mode.

Thank you for shedding some light.

Hopefully someone can confirm this is the case....Min/Max the blower speed is the same.

That is correct for the Volt, and I assume it is similar for ELR. Max/Min settings refer to how much power is sent to the electric heating element or the AC compressor, so it affects how quickly the set temperature is reached and how cold or hot the air feels if you hold your hand up to the vent. On the Volt, there is a small effect on the fan speed, but not much. There is a separate control for fan speed, so you can control that if that is what you want.

That is what I wanted to confirm.

I find it odd for Min/Max setting the Fan speed is the same. But when in ECO, the speed decreases a lot...that is why I questioned shouldn't Min be the slowest.

EU spec Gen 1 Volt has those same Min / Eco / Max settings, I think they are called differently in the NA Volts? (Fan only, eco, Comfort?)

Anyway, I can confirm this behaviour also. For example, if I set my climate to Eco setting, and temp to 22C, the blower usually blows at a moderate speed. If I switch to Min, blower speed is increased a bit and if outside temp is much colder than 22C, the fan speed gradually climbs higher the longer I keep driving. I think this is at least partly due to the computer trying to ensure the windscreen stays un-fogged without the use of heater. In these cases I control the fan speed manually if I feel the fan gets too noisy, the windscreen usually stays clear even with a slower fan speed. I also set auto-recirculation off if I use Min setting.

Max setting also uses a higher fan speed than Eco. But unless I crank the temp way up, (auto) fan speed usually won't go as high as it goes in Min. Just higher than in Eco...

If you set a temperature, then the min, eco, max are how quickly the car tries to get it cool. It's a sliding window. If it's substantially hotter or cooler the car will ramp up the speed and compressor. Once the temp is reached the fan then behaves differently, max circulates it much quicker, eco just a bit and min, still a little. The car tries to move air especially around the dash and defrost at all time to keep the windows from fogging up.

The only way I know to stop the fan entirely to to hit the chevron for the fan speed in the middle ( fan off ). It kills the fan completely.

If you set the car to LOW or HIGH, the car will go all out in any setting.
