Air Conditioner Fan In Dash Stopped Working ?

Hi guys, this is a issue i had with my car and no one knew the answer to it when i asked so I am posting up the issue and fix so if anyone else uses the search function they will be able to find a fix.

A little while ago i turned my air con on and it started working for about 10 seconds and then it stopped. The fan just stopped but the compressor was still on and was still cooling the air but there was no fan at all to get the air into the car.

After a lot of mucking around, i got my mate to bring over his r33 so we can try and change over the climate controll unit, he said we should try the Fan Speed controll unit first (being a auto air conditioner mechanic he said it was common)

This unit is under the dash on the passenger side of the car, you have to take your glove box out to get access to it, 2 phillips head screws and one plug, changed over to my mates one and it worked straight away. WIN!!

I phoned the toy shop and they were asking $95 for the part, i refused to pay that much and wanted to try someone from here on the forums but then i remembered we had a R32 front cut in my mates garage from converting his r31 to a rb20 so i stole the part from that and it fit and worked!!!

So yeah the R32 fan speed controller works in the R33.

Just wanted to post up this info to help anyone else that has this issue because apparently its a common issue in all cars. If this post helped you then reply so i know i at least have not wasted my time :bunny:

I took some pics of the speed controll unit. the part with the fins goes inside the air conditioner unit.

I took the black cover off it and it looks like it corroded around some of the joints... maybe pull yours out and clean them up and re-solder them to make sure they are not dry joints and put it back in to see if it fix's it before buying a new part?

hope this helps!

I had my fan die suddenly 2 weeks ago...

Checked all the fuses and they were OK.

Did the climate control test and come up with 20 - meaning OK

After seeing this thread, checked out the fan speed controller unit - took off the black plastic part and it looked ok, but when i lifted the electronic board I found the issue straight away...

check out the pic to see the solder of one of the connections came off.

Thanks for this thread Guilt-Toy, you didn't waste your time. :banana:

Saved $95 and the hassle of trying to find another one. :thumbsup:

Awesome work fellas,

My air-con blower just died & turned out exactly the same as peterns - same connection exactly. Swapped with mate to check. But yeh that coppery looking band had some off in the same spot - will try soldering it up tomorrow (i'll post some pics)

Big Cheer,

Pen

Yeh worked. I have some pics. If you have a similar problem - ie the Air-con Fan Blower is not working when you cycle the Fan button on the control - I would recommend borrowing one of a mates & trying that. If it works then pull your old one out & pull it apart & look under the lid for a broken copper looking connection. Then desolder the 3 pins on the other end going to the chip and pull off the top circuit board . Resolder down the copper looking connection and then resolder down the 3 pins. DONE & DONE!

I'll try this out in mine - in addition to only blowing air out of the window vents, it is convinced it's -23 outside constantly and won't cool any air down argh!

that sounds more like the PBR is stuck with the vent closed on warm air only

look in the driver side footwell you'll see a small motor with a moving and and a rod connected to it, disconnect that rod and move it manually in your direction untill you hear a THUD which indicates the vent closing

Well had a look and with the R34's turns out you dont need to remove the glove box at all. If you look up whilst under the passenger footwell you will see a black thing with a white connector running to it. Unclip this, remove the 3 big screws and the whole fan assembly thing falls down.

Checked the copper film and it hasnt come away from the solder on either side. The fan is siezed so im assuming thats the problem. Anyone know of a good wrecker i can give a call?

Many thanks in advance and sorry if this is classified as hijacking your thread.

Ado POtato.

      Never ending fuel pump drama

      By Murray_Calavera · Posted

      So last night pulling away from the lights, I lost power for about 1 second. Bit weird, but I kept driving... 5 minutes later the pump completely dies. When I tried to start the car, the pump won't even prime.  I left the car for about an hour, tried to start it and it all appeared fine. Pump primed, car started, got the fuel pressure I should have.... Start driving home, 5 minutes later it dies again. I'm stuck in a shit spot this time going up hill with a car right behind me, so I just let the car continue to turn over while praying to the fuel pump gods. After about 2 minutes of turning the engine over, the fuel pump came back to life and I got home (only about another 5 min away).  So I've been digging around online, it seems like the 525 fuel pumps really don't like to be run at 100% all the time. I've found quite a few examples online of people killing their Walbro 525 pumps within about a year of usage when they are run without PWM.  So, my pump is an Aeroflow 525 (AF49-1057) and I've been running it at 100% without PWM. I'm thinking the Aeroflow 525 didn't like being run at 100% and has burnt itself up.  I really am sick of dealing with fuel pump issues, my current thoughts are -  1. Use a Walbro 450 and run it without PWM. It seems like these pumps hold up pretty well to being run at 100% all the time. I only make about 350kw and can't see me making any more power any time soon so this is probably a fine option.  2. Get a Walbro 525, run it with PWM. I know doing this will annoy me as I feel like with only 350kw, its extra expense that I don't "need" and I'll be thinking the whole time while setting it up that I should have gone with option 1. I know I'll be happy with this option when its setup and running, its only the initial setup frustration and cost as an issue.  3. Get a Walbro BKS1001 brushless pump. This is the fu*k it I'm already going PWM, might as well go full retard. This option just seems better in every way, with the only downside being cost. But I don't know much about this pump so I could be wrong.  Happy to get everyone's thoughts before I go digging around in the fuel tank again.

      Like loud exhausts? You could be a psychopath.

      By GTSBoy · Posted

      Actually, it is probably pretty legit. I mean, it's still woke feminazi bullshit academia, but you would have to agree that it is very likely that there would be a correlation between wanting a loud exhaust and scoring at the unpleasant end of the scales for dark triad personality traits. The fact that they found it didn't correlate with narcissism and only with psychopathy and sadism definitely shows that the loud exhaust thing is more of a "f**k you" than a "look at me", and I reckon that rings pretty close to most of the dickheads who take it to the extreme. Remember, this is correlation with tendency to be closer to one end of a personality trait scale than the other end. Of course someone who is at the literal opposite end of the psychopathy scale is going to be so considerate of others that they wouldn't even think about wanting to upset anyone with a loud exhaust. So the finding isn't that "you are a psychopath". Just that you score more towards that end of the scale than someone who doesn't like loud exhausts (on average, not necessarily even for specific individuals).
