How many Aussies have a faulty A/C controller

[SweetChuck]

I'm curious as I've worked on 3 units recently and they all had the same problem and all were 91-94 models. A tell tale sign of imminent total failure is the fan speed either goes flatout or not at all, despite setting .

This is old news to those that have been around a while, but a timely reminder.

It's a well known fault that can cause serious damage to the trackwork on the board from leaking capacitors. All 3 of the one's I've repaired had badly etched tracks to some degree.

I urge all Aussies to check their unit as a replacement is rediculously expensive and hard to find. Even if it is working properly and you know what you are doing, pull it out and examine the board. If you see any corrosion like in the pic attached , it needs repair ASAP, as it will only get worse.

Have apparently two issues with mine, the usual fan only on high and also something to do with the sensor for the flap adjustment not reading properly.
Was about to send it to America to get repaired, i was not aware you also repaired them.

Hi Sweetchuck,
I have a 94 model with the usual problem, 18degrees c and high fan speed. Waiting on mate to help remove unit. please advise your contact details so I can forward unit to you.
Cheers,

Good to know that you can fix them.
Mines running fine for now but who knows in the future.

I'd still check it out next time you have the console off, easy to check and repair early

Yes I can repair them no problem, day job is electronics engineering.

I don't want to be out of line here though and step on anyones toes, or break any site rules. So by all means PM me any interest, and I may make a Aus vendor page for anything NSX electronics as it does take a lot of time and shipping costs sending these modules abroad when we can use the brains trust in OZ !!

Will vouch for SweetChuck. I believe thats my board pictured in the initial post.
Just need to get down to whrdnsx on the weekend to swap him back his a/c unit whilst you repaired mine.

I think the board in the pic was off the black NSX I have here, yours was in pretty bad shape also.

They all fail and I have seen some in very bad shape. Most I am able to save but the sooner I get them the less work it takes to get them back in working order.

Hey Sweetchuck,
don't supose you fix head units?
Cheers Owen.

Never have , but if I can find schematics I don't see why not .

My '99 flap makes a screeching noise when it changes. Is this something that can/should be fixed or just live with it?

P.S. Brian K did a quick, reasonably priced capacitor job on mine a few years ago; Still works but responsiveness to dialling in temp changes is a bit hit & miss

Its likely a repair will fix it. Which flap?

Not sure; under-dash noise related to aircon; How do you go about diagnosing it?

I would run the test procedure, http://www.nsxprime.com/wiki/Trouble...Control_System
and see if you get anything.

Took mine out today.........CCU was working perfectly.........BUT.......some caps have leaked.

Was going to fix it myself but will put it in the safer hands of SweetChuck.

It is wise to get to them earlier, yours would have failed without a doubt.

Got my board back from Rick today, sent out Monday so fantastic turnaround!!!

The board left a bit worse for wear and now is sparkly clean.

I'd highly recommend Rick for service and expertise............

Remember, even if your CCU is working ok, I'd take it out and have a look.

My NSX had only done just over 75,000 kms, garaged most of it's life.....and it had signs of leakage on 4-5 caps. So it probably would have went within a couple of months.

PM sent,...... could be a good time to have this checked, it will be warm again in Melbourne before you know it!!!! ( yes, I'm being sarcastic about Melb weather)

[IAN94]

Sweetchuck strikes again, CCU board back, fitted all OK. as you would expect.

Thanks Again,
