so im just trying to get my climate control to blow cold air. i have removed my air conditioning, but it should still be able to blow ambient air but its not. only blowing full hot air. trying to see if the actuator arm wasnt moving i removed all my center consol and no matter what temp i set it to the arm doesnt move. i then held the cold button and it said fast cold and the actuator arm moved all the way to the other side.. so the actuator is working. i then pushed the ambient button and it said -30 so i was trying to find the sensor and i think it was cut off or something. its only a simple 2 wire sensor, so i was wondering if i could just use one from a nissan pathfinder or something? im in canada so skyline parts are kind of hard to find at the store.

so ya,

-can i use a pathfinder ambient air sensor??

-would this be the only thing making it blow hot air only??

so the altima sensor did work. and now code 21 is gone, and when i push the ambient button it shows the temp, so thats fixed.

now the air mix door actuator doesnt work at all. before i installed the air temp sensor i had codes 21 and 27. now i have codes -26 and 27... any ideas what could have happened?? all fuses are ok.

the first time i turn on the air controls the air mix door actuator actually moved all the way over to cold and then all the way back to hot and now it wont move. even if i select fast cold it doesnt move like it used to..

Great news.

Codes are 26-pbr(air mix door/hot cold blending flap) and 27-refigant temp sensor(other evaporator temp sensor)#

Have you already tried giving the actuator a push with your fingers, sometimes over time it gets dust - etc jammed in it. This is what I had to do with my old R34 mode door. Dont know how a 32 one looks, but the metal arm on mine had also come loose - hence why it was not moving. Does yours have one and if so, is it still attached?

Worst comes to worst, may need to change the actuator if after push / lube no success?

sensors are all hooked up, but arcon still does not work though. i cant control the damn thing, sometimes its hot when i selected cold and sometimes its cold when i select hot. it sucks in the mornings when i go out to let it warm up a while by letting it run with heat blasted and when i go back out its like a refrigerator

for future reference, if you hold the off button on your climate control for about 5 - 10 seconds as soon as you turn the ignition on it goes into diagnostic mode. look it up and you can work out error codes, faulty sensors and circuits. have a play around

so ive had a play around with the diagnostics. and i got code 25,26,27 not worried about 25 becasue it was cloudy out. 26 is the mixing door and 27 is refrigerant temp sensor(removed air conditioning) so i think 25 and 27 can be completley ruled out? and 26 being the mixing door makes sense. did a sensor inspection and outside temp was 23 inside temp was 21 (was only like 14 out but not too off i suppose..) the suction temp was -30 though! and same with refrigerant temp(but im guessing becasue air con was removed correct me if im wrong).

so if i fix the suction air temp sensor maybe that would fix the mix door code? i think i read somewhere can be fixed by just taking the sensor out and putting in a certain sized resistor?

anyone have a picture showing where suction temp sensor actually is?

    • Dear folks My family members have 4 different cars : Triton 2015 and Corolla 2011 and Mazda3 2012 and Hyundai Elantra 2014 Looking to buy engine oil funnel spill free What I found are are below  https://www.amazon.com/gp/aw/d/B0BBTTJNKX?ref=ppx_pt2_mob_b_prod_image&th=1 https://www.ebay.com.au/itm/145553221359?srsltid=AfmBOoqYBU6Ptw0LU_bAp_k67U3qkF97HHvePkA7iHZw8vUmiwoIRaRr https://www.amazon.com/gp/product/B09X23TCS5?th=1 Is there a funnel with attachment that fits most cars ? Don't mind to spend for a decent quality  Thx  
    • Stock ECU (or more accurately stock tune) absolutely refuses to go over 10psi and behaves like you have seen. The Nistune is the same if it is the stock tune. If the Nistune chip has been tuned, the resulting tune could be literally anything for any combination of parts. The Nistune just makes the stock ECU Tunable.
    • So stock ECU does not like anything above 10 psi?  That Nistune one is just for "try" if it will be any different, I know it need to be tune for that. I know but YOU may know about these problem but i/we dont. They few little Skylines here let alone people who know anything about tham so that is why iam asking here  
    • So now we have a radiator with no attachments whatsoever. It lifts up with a particularly tight spot between the drivers side air box mount and the lower radiator outlet, but if you've got this far you will sort that too. This is the lower mounts with the rad out so you can see where the rubber bushes go, it is a straight shot upwards Done! Assembly is the reverse of disassembly, with blood less likely to be shed.
    • Right, onto the second last trick. The Air Con condenser is mounted to the front of the radiator and stays in the car when the radiator is removed. There are 2x 10mm headed self tappers holding the top of the condenser to the radiator, remove those The bottom of the condenser is attached to the radiator with clips. You need to lift the condenser out of those clips and clear (up, then forward). f**ked if  could work out how to do that last bit with the front bumper on. I hope you can, and you share the trick.  Bumper removal probably deserves its own thread one day once I've recovered the will to live, but basically you need to remove the wheels, front inner guard liners (clips and 10mm headed bolts), the self tapper between the guard and the bumper at the rearmost point of the bumper (same as an R32 that bit), any remaining clips at the top/front of the grill, an absolute bastard design with a plate that holds the top of the bumper above the headlight each side (only 1 bolt which is tricky to get to, but the plate catches 2 places on the bumper and must be removed....carefully!) and push clips between the bumper and guard under the headlight. If you've done all that you will be faced with wiring for the fog lights on both sides and in ADM Q50 RS at least, 4 nasty tight plugs on the driver's side for the ADAS stuff. So, the clips at the bottom look like this on drivers side (looking from the front) And on the passenger side (also from the front), you can see this one is already out Clearance on both of these are super tight; the condenser needs to move up but the upper rad support mount prevents that, and the radiator can't move down far because it is (rubber) mounted. Once you achieve the impossible and drop the condenser off those mounts so it does not stop the rad moving, you are good to go
