Help with AC please

[Michigan NSX]

I will check my fuses.

The weird thing with my system (also a '91) is that although I have the same problam as SilverOne when using one if the AC modes (face/feet & face, etc...), ie when not on MAX I just get cool air, If I turn on the AUTO function (the middle of the left knob) I can vary the fan all I want and it works properly. I just can't direct the cold air where I want it.

Thanks to everyone for their research. If I ever do find the problem I will be sure to post what my cure was.

I checked the fuses - they are fine.

Check the postings in Silverone's thread---a check of the AC system can be completed. I added to that info....If you have a service manual the info can be found there also---see Technical and look for Silverone's thread again...Turns out I had just blown a fuse on my left side....Could be that your mixture air door is sticking
