NSX heater fan switch not working-- ideas?

[Steveffl]

Hi all.... I have a 1998 with 34K miles. Everything has been working fine, however the heater control rotary switch (the right side one) doesn't work correctly. The only way you can get the heater blower to work is to turn it on full blast. It doesn't come on in auto, or in the manual mode.

Does this sound like just the switch or something more sinister? Is the switch difficult to replace, and should I start there? I am not a mechanic, so anything much harder than an oil change I take to the dealer. Thanks much, Steve

^ +1. Most likely its the classic NSX CCU failure, and no one has more expertise world-wide on CCU repair than BrianK. Stay far far away from the dealer on this, unless you only use them to remove the unit and mail it to BrianK.
