hey Guys and Girls,

completely out of no where, my fan has just stopped working in the car (98 Stagea RS)....

no matter what fan speed, turn it on and off, whether i got it on hot or cold temp - no fan at all!!

If i turn on the AC - i can hear the AC compressor turn on under the bonnet, and if I set it to allow air in from outside its ice cold air coz the AC compressor is on....

but still, can't get the fan going, checked all fuses - nothing is blown?

anyone had this before?? i was thinking of disconnecting the battery incase something needs a reset....???

any help appreciated!!!!!

That happened to our wagon a few months ago. First I took the fan out of the car and powered it up to a battery. Fan was ok. Then I went to fuse box in enginebay, found fan fuse and removed and installed a few times. Fan hasn't stopped since. All I can put it down to was crusty terminals??!!.. hope this helps. Happy boosting.

Probably dumb question, but which fuse (whats it called) in the fuse box is the one for the fan??

I had a look at the aircon one - but thought that might be the one for the actual aircon compressor??

which one did you pull out/clean??

Happy Boosting to you too!! :blush:

Not sure of which one was the fix, it was months ago?? But I would go both A/C fuses and motor fan fuses. All I did was remove and replace a couple of times each. Did you check fan is ok, off a battery?

well its not the fuses, I took out evey one, cleaned the pins with a bit of sand paper and put them back in, still nothing....

disconnected the battery for a few hours - nothing again....

can anyone please show me where the 'how to fix' thread is for the electric motor? all I can find is the how to clean your aircon filters... but not the actuall electric motor... is it also behind the glove box?? unfortunately its time to test with a battery as advised above and replace if required... :laugh: really CBF'd!!!

also anyone know where i can buy a second hand/reco motor in the northern suburbs in Melbourne??

Cheers!!

Easy to get fan out. Look in under glovebox, fan has 3 screws holding it in, plus power plug. CBF???. You will miss aircon!!

ok ok i'll look at it this weekend!!! LOL

I really CBF'd but its something I must fix, its my wifes car at the moment with our little one and the aircon must work - not good driving a little one around in a sauna!!

thanks for your help skidkid!!! :down:

No that is not plug for fan. The screw directly below your little finger in pic is one of three screws that hold fan in. If you take the 3 screws out, plus remove power plug, fan will fall out on floor if you don't catch it. Hope that helps.

Unfortunately it wasn't just a matter of cleaning the pins....

plugged a multimeter into the connector... its only getting 0.3v (which is sweet F**k all!!)

I would love some suggestions for the next thing to try....

or is it time to take it to an auto elec...?? if so, can anyone reccomend a good one in northern subs. Melbourne?

pull out anything to do with the electrics of the fan (maybe the control unit thingo)

open it up and check for bad solder joints - your still getting some power, just not enough

google what bad solder joints look like

if they are bad all you need do it heat them up a bit, maybe whack some new solder in and your done

its a common problem on 32's due to older age, guess you got unlucky

pulled out the control unit thingo - all the solder joints looked fine - went to wreckers to try plugging in another one incase the relay in mine was stuffed - and the dude at the wreckers reccomended testing the climate control resistor / heat sensor (what ever you wana call it.....)

so he grabbed another one from an R33 (looks like they're the same), plugged it in - and guess what...!!! THE FAN STARTED WORKING INSTANTLY!!!!!!! FIXED!!!!

turns out another dude a few weeks ago had the same problem in a WRX - and thats how he fixed his problem too!! :)

so anyone else has a similar issue - now you have another thing you can check!! :D

I've been having exactly the same issue. Mine seemed to start randomly when the temp outside got to 33-36 deg.

So ok, thought metal expansion/contraction... Also if i hit a decent bump it would come on.... thought number two, something loose..

Pulled the fuses and replaced, swapped out the two relays (behind fusebox under the dash), checked the loom etc disconnect battery.

Fan is fine, bench tested it

No Joy....

Now that I've located this thread, which im glad i did, thanks for the tips/discussion, im trying the sensor... give it a wiggle/tap/clean terminal fingers crossed, if not down to the wreckers to try a replacement.

If none of that works, temp fix,,, fuse/relay/on off switch and connect the sucker direct to the car battery!

(ps. use a multimeter to see how much amp draw and use select correct fuse)

Will let you know what happens.

I replaced my sensor today, also got one out of an r33 at wreckers. All is working again! so happy to have aircon back!

Looks like some of the older maximas/pulsars use the same one also, but someone had already removed them so could not compare..

im about 99% sure they be the same.

Had the same problem. if you open up that fan speed controller and unsolder the board, underneath there is a copper link that in my case had come away from the board.

Resoldered and problem fixed!!

Have a look and you might find its the same problem, You'll then have a spare one :)

      Feedback on Carbonetics: R34 GTT cooling panel

      By IM-32-FK · Posted

      @DraftySquash @Duncan he's not talking about the part that sits against the radiator support, he’s talking about the lip that sits towards the front outside of the car. anyway I had a look at other cooling panels and came across this one https://justjap.com/products/carbing-radiator-cooling-panel-plate-nissan-skyline-r34-gt-t?variant=37829684134087&currency=AUD&utm_source=google&utm_medium=organic&utm_campaign=Advanced feed&utm_content=Carbing Radiator Cooling Panel Plate fits Nissan Skyline R34 GT-T (Coupe)&srsltid=AfmBOoonzPDKqe9NgKi5U0AkFc2XvbXETGmNWvfNcyBT5DUZagMYHg9DZ70 if you take notice it’s the same shape.  well thankfully the justjap listing has a description and it says : - Nissan Skyline R34 GT-T Coupe (M/T -07/2000) this means it’s specifically for a s2. S2’s have different front bars to s1 so that lip with the 3 holes are *probably* mounting points for the s2 bar. im not 100% sure but im almost certain it will still fit a s1 bar

      Everyone is too used to learning from places like HPA "how to tune" and what to expect at what point, rather than being able to see "The computer says I'm in cell with Row = 8, column =4, and I can see my fuel is lean, so lets add more" Everyone wants "real units", which helps for someone picking it up for the first time and seeing how bad the tune is if they're not used to touching it.   However, I think for most of us who want to play with it, you're 100% right, we're only needing to learn about it for OUR CAR. Which makes it great, and we don't need to care what the real values are, we just need to know which cell it is, that's causing the lean or rich point, or that we want more ignition timing or less. But again, everyone wants everything super you beaut and nearly self tuning, with VE maps, and a billion compensations...   Though then there's me over here when I'm doing reverse engineering work just reading data in hex format that most people couldn't work anything out from. Yet I can see what's going on.
