Hello again, just wanted to say that i finally got some answers today to this problem. I measured the voltage from the cables going to the pressure sensor and got a couple of volts difference when the ac button was on and off. I then tried to jump the cables as you suggested and low and behold now the button could trigger ac request and ac clutch and the clutch actually turned. It's funny because i had my local Subaru workshop look at the ac a while back and they said it didn't connect from the ecu to the compressor. 2 weeks ago it was at their place again and i wanted them to fill the system but the mechanic misunderstood the work order and said when I picked it up that it still didn't connect from ecu to compressor but he vacuum tested it and it didn't leak but it was empty. Can't believe they didn't know the ac doesn't trigger when there is no pressure at the pressure switch. They will fill the system next week and if it doesn't trigger then i guess the pressure sensor is bad, looks like I'll be enjoying ac this summer which is nice since it's said to be one hot summer here in Sweden

Im also curious why the ac button doesn't trigger di3 ac request. If I get the ac to trigger there is no point if i have to do it in the link software and not with the ac button

No the clutch didn't engage but i could hear a relay click when doing that. I also tried to change the pullup resistor to on on Ac request and took a video (https://imgur.com/a/Lkc2Kr7) when ac clutch turned green this time i didn't hear the relay click but when ai 7 engine fan 1 turned green the engine fan actually turned on

It's a wrx 107+ So when I'm in the ecu Ac request is on digital input 3 and Ac clutch is on Ai 6 but when I checked if the ac button made anything turn green it didn't. I also tried to turn ac request and ac clutch on manually through the link software but the ac didn't turn on at all. I'm hoping it's just a matter of telling the ecu which pins the ac is connected to or something along that line. I'm completely new to playing around with my link ecu since my engine builder and a tuner have done everything so far

Link g4+ Pnp in a Subaru sti 2006 ej257

Hello Ever since i got a link g4+ installed by a tuner in my sti my ac has not been working. Found out that it was because the ecu was switched since the ac kicked in when given a direct power supply. Today i managed to connect to my ecu for the first time and did some digging around and i don't get a single response from either ac request or ac clutch when pressing the ac button. So my first question is since the ecu is plug and play should it recognize the ac button signal or does that need to be connected somehow when installing and my 2nd question is if it should be recognized by the ecu what would make it not be?

Hello Ever since I got my g4+ PnP my air con has not been kicking in. I guess its some settings that need to be done in the engine management software but I am a complete noob that has not connected to my ecu even once. I might need some guiding on what to do so I don't accidently fuck my tune up or something when investigating in the program. I hope you guys might be able to help me diagnose this issue =) Thanks // Some swedish dumbnut
