I bought my NSX about 4 Months ago, one of the pending items needing to be addressed when I bought it was the Climate control issue. I was hoping the problem would be related to a simple CCU repair, unfortunately that only seems to be part of the issue.
I sent my CCU out to SOS for repair, they sent it back to me saying it was not repairable. I then found a company (ASI, www.autoecu.com) who was willing to repair the unit for me. I finally got the unit back in, and all the functions seem to be working, except the fan is stuck on ~80% power, always. When I rotate the fan control to full, I do hear a slight change in the fan speed, but anywhere between off, and 3/4 speed, it will run at 80%. My only option to shut the blower off is to pull the blower relay.
I had thought the problem may lie in the power transistor, so I checked the 3 pin plug at the transistor, and was looking for and have full 12.5v at the blk/blu, and 0v at the Grn/blk, regardless of the fan speed selector position. This makes me seem to believe the CCU is still bad, however, I just got it back from AutoECU and everything checked out on their end.
Any ideas before I go soldering in a new power transistor?
As always, help and input is much appreciated! Thanks guys.
