Blower fan speed

[Christo]

I have a 1995 NSX and my blower fanworks only on high speed. I have read the Acura service bulletin 92-007 and my dealer said that these problems ie blower motor current draw and power transistor failure were corrected for the 1995 models. Should I assume that my problem is connected to a resistor found in the main control panel. If so is there a part number for this resistor. Any help will be appreciated.

I had this problem as well... I just had it repaired a couple of days ago and am VERY happy. Mine only worked on high as well... check this thread for details...

Yes you can assume you have a problem with the CCU control board. The capacitors on the control board fail, leak and damage the circuit board. It's repairable 100% of the time assuming someone else has not worked on it. I replace all 13 electrolytic capacitors on the board and repair the damage to the board the leakage caused.

Here is a good thread on doing the repair inc parts needed.

thanks everyone for the help. I have only had my NSX for a month as I traded my shelby ac cobra replica for it. It will take me a little time to get used to the mechanics of this car as my cobra had a 480 cubic inch ford big block with relatively uncomplicated mechanics and very few luxuries. I will surely be back on the board with other questions.
