R32 A/c Not Cold?

[R33_Smash_Deamon]

Hey

Just tried it on my r33

and it only seems to read 3 temps

a 37,41,5 and it keeps cylcing through those numbers, dont really know whats going on.

can anyone help?

[MAT00]

Yeah mines the same, on 5 it only shows 2 temps, inside car and outsider car. Anyone know whats up with that??

[MUZT3K]

its possible maybe you need to get it regased, because i remember in my r33 the a/c wasnt cold an that was the problem.

[widebody180]

I was having the problem with the hot/cold mixing actuator not working. When I got down in the passengers footwell I tried to move the rod by hand but it was completely stuck. After a bit of stuffing around I got the part with the motor that controls the actuator out and I started playing with it. When the motor was not connected to the other little cogs, it would run constantly. Also the cogs would turn freely on their own, however put them together and they wouldn't budge. Also I think I may have damaged the motor because after a while it wouldn't run at all.

Any ideas of what's going on?

Is it possible to have the locations of all the temp sensors. My Outside, Inside and intake sensor are reporting -21.6 whatever which means it isnt connected or is dead, but as most people have noticed the downloadable workshop manaul's pictures are too monochromatic to define exactly where they are.

I know that the Inside sensor is below the ashtray and from what i remember it looks like a funnel, or is this an airhose for a gremlim inside the dash of my car...

Widebody180: Apparently the majority of motor faults is broken solder points inside the motor box. I saw a tutoral on how to fix it, and you to go through where your sterio and A/C controls are to get to it without removing the entire dash.

Cheers!

I found the interior one, does anyone know where the other two are (outside and intake)?

[Marko R1]

i'd like to know the locations of sensors as well, is the interior 1 in an r32 on the top of the dash passenger side right under the window OR is it the 1 next to the ashtray?

Hi All ,

I have a 32gtr with the a/c not getting cold at all

i have done all the checks and all sensors temps are ok , all door and flaps work but still no a/c

Tried the FC option still no a/c

Had system regased - still no a/c

The compresor is not pulling in at all . the only way to make it pull in is to by pass the relay- then it will get cold

Any ideas as to where to look for the problem ????

Will be getting hot soon so would like it to work!!!!

[jnr_chin]

i have a r32 gts t

my a/c works but not 100% it is not as cold as i would like but i can live with it. i had to disconnect the hotwater hoses coming into the box. From what i have seen the flap is not working. My main problem though is when i turn on the a/c it does not throttle up the car so it will shut off.

my readings are -21, 25, -26, 27 and this is in the night.

questions though

1. i do not need the heater but will the heater flap open caz it not to be as cold as it should

2. does these readings show that any sensors are gone bad? if so whats the fix

thanx in advance

[Cplus]

are they your temperatures or the fault codes at the start?

if they are the fault codes flashing up your system is stuffed!!!

[jnr_chin]

they are my fault codes. so is there no hope ?

i think i am much better off than a lot of people on here with a/c problems caz mine is blowing cool and nice.

what does the codes i have show.

if it is sensors cant i install resistors or something?

[Cplus]

Fault Codes

20 - all is normal

21 - outside air sensor

22 - Inside air sensor

23 - Water temperature sensor

24 - Intake temperature sensor

25 - Sunload sensor (small sensor on the left hand side of the dashboard near the windscreen)

26 - PBR

27 - Refrigerant temperature sensor

you fix sensors by replacing them. you add resistors if they are out of calibration - or - you want to over ride them.

so if my faults are21, 25, 26, 27 how do i know if they are gone bad or need calibration? or will i have to test the temp.?

Hi all awesome thread handy info cheers guys, my ac prob is abit diff.

All the sensors and that seem to be swt but the ac blows ambient air and when I turn it on and off it always resets and goes back to 25 degrees. Anyone had a similar prob? Or able to help?

Thanks Corin

this is normal mate

[Sifty33]

Really I'm sure in other 32 s I've had it wud stay on 18 deg wen u turn it off then on again, will test it on my mates 32. Hopefully I just need a regas aye. Thanks mate

[Marko R1]

both of my gtr's reset to 25degrees but im not sure if its when i turn off the ignition or when i disconnect the batt, u've put doubt in my mind.

[Sifty33]

Hey tested it on my mate 32 yesti and his one doesn't reset when u turn the ignition off, but it does when u disconnect the bat, anyways looks like I'll have to get an auto sparky to have a look

[lowered_skyline]

SMIK YER!!!1 this worked on my car , cost me nothing for the resistors too hahaha i got 2 and they were 6c each but the chick said they were on sale 1c each hahah so she just gave me my 5c back , went to the parking lot put the 2k resistor in and WOW cold freakin air ! love it , thanks heaps for everyones input

i got

20

3 (fault code 3 which is mode door position check) but what is this?

41 (42 - 47)

5 , 36.5 , 43 , -30 , 38.5

i'm pretty confused on wdat needs to be done?

cant any one help shed some light please?
