I need the same thing, went and got my compressor tested and its not getting power, nor do i have any gas. Diagnostic basically says i need to see an auto electrician.

I have a R32. That's pretty ridiculous that auto sparky's would turn down business just because its an import!

Yeah it's really frustrating, my compressor doesn't receive power but I got a re-gas

Been to about 4 or 5 auto electricians and air conditioner "specialist" keep referring me back and forth. Always the same crap from the auto electricians saying they can't touch it cause it's Japanese.

if you have no gas the pressure switch will prevent the compressor operating so it doesnt sieze.

You might need gas first.

Exactly what he said. You could bypass the pressure switch to see the compressor pulley lock in. To prove that part works. Don't try this with engine running. Take the auto electrician a wiring diagram of it next time.

I took it into a air con place and they re gassed my car to do the diagnostics test. turns out I need a new filter canister that sits by the fans as well because my one is old.

So I think the switch is not working or connected as my Apexi says A/C is operating and everything but my A/C fan and compressor never comes on. Glad I have no leaks in my system tho!

I wouldn't of thought it would be a hard fix for an auto sparky. just came to a hefty price to get it all fixed up. The air con place said they would need to take it to a auto sparky if i left it with them to fix up.

It cant be that hard to work out. The AC switch when turned on supplies 12v to the pressure switch. If there is pressure then it sends the 12v to the compressor head which will pull in.

Get a multimeter and check that the AC switch is turned on. Put ign to on but not start. Then go to the pressure switch and look for 12v. If you only have 12v on one side of pressure switch then some how touch the 2 together. This will bypass it and you might here the compressor pull in. If you find there is 12v at the compressor then it might be a bad earth. Every circuit needs an earth return to the battery to work.

Just tell them unless its a falcodore then all cars are imports.

Do you know where the pressure switch is on the R32? In theory this should work without gas, if I test for power on the control side of the switch, i could bypass the switch like you said with or without gas to see if the compressor works. Then all i should need is a refill :) Im hoping its just the pressure switch. I dont know where it is tho :/

      Boost cut after swap(RB25DET NEO) R34

      By GTSBoy · Posted

      Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.

      Boost cut after swap(RB25DET NEO) R34

      By Kapr · Posted

      Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler

      Can you clarify what you mean by boost cut, do you mean it misfires both when under load (driving) and when stationary and out of gear? Or does the ECU pull power when it reaches a specific boost level that is too high (boost control issue)? Does it occur at idle with no throttle? When you say "the ECU is OK", what ECU is it and why do you think it is OK? Have you used the NEO ECU, and if so do you have a MAP sensor attached? Same for the AFM, why do you think it is OK? Do you have any way to put a fuel pressure gauge on it (even just a mechanical one between the fuel filter and fuel rail)?
