Even same generation dont mean aircond panel / fan speed levels are the same.
Below are 'same generation':
1) GM6 before FL: manual aircond (all spec the same)
2) GM6 after FL (GM6.5) : S spec still manual aircond, E/V get digital aircond.
I assume digital version get slightly more fan speed level than manual one.
You still sure you are comparing like with like?
Hmm... so in this case, it shall be different between Jazz Highest Spec and the pre-fl city highest spec, although both also with digital aircond.

If you notice significant difference in air volume since it was new, then it's a sign of weakening blower motor.
Maybe have to ask the SC to check the blower motor

Not sure
If you're talking about fan speed or temperature control.
Is it even like for like?
In any case, just take your car for AC check and service at the nearest Denso and maybe change the cabin first element if you haven't.
For your own peace of mind.
I am talking about the fan speed.
Service at the nearest denso? Like shop that service aircond?

First, do confirm what they say is true by testing it yourself. If so, a few reasons I can think of.
- blower not receiving enough power supply
- blower is physically sluggish
- dirty cabin filter (you can remove it and test the air flow to see if it improves).
- dirty evaporator. The evaporator is located downstream of blower - this is bad as it's inaccessible without removing dashboard, and a blocked blower discharge causes surging (high pressure low flow) which is bad for blower.
Edit: IMO, it's best to compare air flow by having the speed at min, medium and max for better comparison.
Edit 2: low air flow can also be caused by ice formation on outside of evaporator, which blocks the air. If you turn off the AC (to swich off compressor) and air flow doesn't change after a few minutes, you can rule that out.
This is a very detailed reply.
Erm, what you mean by the Edit 2, if turn off Ac, and air flow doesnt change after a few minutes? If turn off AC, then there shall be no air blowing out right?
