Default Please help!! A/c wtf issue

I'm sure you've all heard that Port Augusta reached 49.7C on Thursday and because I live around that general area A/C is vitally important!

Jumped in Sh!tbox (has cost me $14k in repairs recently and still counting) today and turned on the A/C which has been the ONLY dependable thing on this tub, only to find the following conundrum.. Tub is '09 Thai D40 King cab YD25.
  • A/C light is on
  • No fan blowing in postions 1, 2, 3
  • A/C motor appears to be running (power draw)
  • Move to position 4, fan starts blowing, but A/C light goes out
  • Max cold air blows for 10-15 seconds before just blowing regular air
  • I'm banging my head against steering wheel and no amount of ripping through all A/C non-A/C settings makes any difference
  • Fuses are fine

I am at a loss and 150kms from my nearest repair shop. Can anyone decipher this enigma machine?

its common for the fan resistor to blow on D40s. if your fan still runs, albeit only on 4, it could be this. took me 2 minutes to fit!

Cheers buddy, if it's that cheap and simple I will shout the bar!

Cofirmed. Resistor it is. Plenty of videos showing that this is a common issue across the globe to Fronteras, X-trails, Sh!tboxes etc.

Thanks again!

It is a common problem unfortunately.

I do recall someone on the forum supplying repaired ones. Or maybe they were genuine but cheaper.

I wonder how well a potentiometer would work for controlling the fan speed. Obviously there would only be one fan speed as far as the switch is concerned (just on and off) and a potentiometer for adjusting the actual speed of the fan. It would mean infinitely variable fan speed adjustments but I don't know how well it would work in practice...

I probably bought mine from the same seller, Eric! Cheap, 2 minute fix, hasn't failed since.

I am so close to burning this P.O.S Nav it isn't funny!

Changed out the resistor with genuine Nissan unit. A/C worked perfectly again for 1 ******* day, then went west exactly like the first one.

Any idea why this unpolished turd is suddenly blowing resistors? I've done nothing to the pig-tit electrically lately. Haven't had issues up until now. Why? Why why why why why why why!?!?!?!?!????

The cheap blower resistors are made to a price not a standard
My brother used a cheap non branded ebay one in his renault clio and it lasted a couple of days
A friend used an ebay one in his holden rodeo and it lasted a few hours
I know theyre expensive but genuine ones are generally made in japan or germany and will usually last decades not hours

Sorry i misread the previous post, didnt realise you used a genuine unit.
Was it new or from a wreckers?
If it was new it was more than likely a manufacturing fault and you will get your money back or a new one under warranty

Its possible theres a high current defect with the fan motor itself but thats pretty unlikely
