As an avid reader of this section of Prime, I've come to recognize that there is a sub-culture of NSX owners who have both the confidence and expertise to deal with almost any problem that may develop in their cars. However, there also appears to be a significant number of owners who, when confronted with complex problems (e.g., climate control control modules), ask for help on this forum rather than have them fixed by a dealer or NSX specialist. From the wording of their posts, it appears than most such owners have neither the confidence or expertise needed to actually solve the problem. I know for some, DIY is part of the joy of ownership. But for the mechanically challenged (and believe me, when it comes to a very sophisticated car like the NSX, most of us are in that category), why not attack the problem directly by bringing it to a qualified shop? Is it just a matter of money?
