Question in regards to heater fan knob?( air pressure )

[Lime Green NSX]

Hello, a friend with a 91 NSX would like to know what makes this happen.

When he turns on his heater on auto and it doesn't make a difference what setting you have it in or if A/C is on or off. When he adjust the heater control knob and turns it all the way on there is no air coming until the knob is fully turned on, so he jsut gets a blast of air but as soon as he turns it down he losses it again. What would control that or be the reseaon it would be doing that. thank you in advance!

Well I guess heater fan controls dont come up but I guess climate control and blowing does!

thanks.

Yes the fan only runs on high is the most common problem seen with NSX climate control units. It's time for your friend to get his CCU repaired. Email me and we can get the process started.

Thanks, I just got off the phone with him and he thought it was that. Would you be able to tell what resistor has blown?

I fix about 100 CCU a year so I am sure I can find and fix the problem.
