I experienced this with my car before the controls packed up all together, so I'm almost certain your heater control unit has developed a malfunction.
Contact Kaz, who repaired mine a few years ago, will no doubt confirm what I think has happened to your climate control unit.
If so you will just need to remove it and send it of to him so he can do his magic.:)
Good luck anyway.

Hi, Jamie.
If you are saying that there is no air flow from any of the vent/mode, then try rotating the fan speed control dial located at the right side all the way clockwise to max speed setting. If suddenly you started to get the air flow but only when the fan control at max speed setting, then this is a typical A/C Climate Control Unit (CCU) failure mode.

If you are saying that you don’t get any air flow from the centre vent even when manually selected but fine in other vent/mode, then you may have issue(s) on the CCU, mode motor, linkage wire, etc or simply something obstructing the VENT mechanism.
I saw security, ICE, etc cables blocking the mechanism from time to time.

As in NSXGB's post, try the method from Wiki on NSX Prime. The original is actually from the workshop manual attached below.

finally getting around to sorting this issue- how much work is involved in sorting these potential issues?

are they time consuming/ costly?

Hi, Jamie.

Could you provide us with the answers to the questions in my previous post above?
Depends on the answers, it could be simple as replacing just the blower motor relay or it could be more serious and your CCU board may need majour refurbishment if it is the main cause of your issue(s).

I not need to add much more to this as Kaz covered the points. But more info would good.

All I can add to this is, on a few NSX when they were in for refresh, I removed vent and air blowed out the cluster build up they get over years, I do this with air gun by compreser, but you have to know what your doing and compreser speed. The amount of dirt, hair, mould etc would blow you away!

I have also used the same method on the Lambos, Mercs, porch, etc that come in and they are same.

Other issue as Kaz would know and tell you is......The electrics. He told you already what to do there.

Please share more info.,

Kind regards.....Sudesh
