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 :/

      You just need to remove the compressor housing, not the entire turbo. I would not be drilling and tapping anything with the housing still on anyways.

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      So, I put my boat on a boat. First of all, I'm going to come out and say it. Why is Tasmania not considered a holy goal, an apex that all road-legal modified cars go to, to experience? This place is an absolute wonderland of titanic proportions. If people are already getting club runs for once in a lifetime 30 person cruises to Tassy then I've never seemed to see it. It is like someone replaced the entire place with an idyllic wonderland for cars, and all of the people living there with paid actors who are kind, humble, and friendly. Dear god. After doing a lap of almost all of the place I've found that it's a great way to find out all of the little things that the car isn't doing quite right and a great way to figure it all out. All in all, I drove for 4 hours a day for a week and nothing broke. I didn't even need to open the engine bay. This is by all means a great success, but it has left me with a list of things to potentially address. I also now have a 3D printed wheel fitment tool which annoyingly hasn't got any threads in it to actually assemble it. I might be able to tape it together to check the sizing I actually want to use, but it'll likely involving pulling the shocks out to properly measure travel at least at the front, and probably raise the car while I'm at it, at least in the rear. I scraped on quite a few things and I'm not sure how else to go about it. I was taking anything with a bump at what felt like 89 degree angles. And address those 10 other tasks. And wash the car. God damn it is dirty. And somehow, the weather was perfect the entire time - And because I was on the top of Mt Wellington it turns out it was very much about to freeze up there. I did something I typically never do and took some photos up there in what must have been -10 and the foggy felt like suspended ice, rather than mere fog. If you own a car in Australia, you owe it to yourself to do it.

      R32 gtr transmission strength, billet plate

      By cosline · Posted

      Hi, I have a r32 gtr transmission. Does any of you guys have an idea how much power it will hold with the billet center plate and stock gearset? At what power level and use did yours brake with or without billet plate? Thanks, Oystein Lovik

      Spotted on the street....

      By Rezz · Posted

      Saw this replica police car based on a Mitsubishi Starion XX parked next to a 'police box' (it's literally a box) in Hirohata, Himeji City in Hyogo prefecture the other day. It's owned by Morii-san who is a local Mitsubishi Starion enthusiast. According to a local radio station blog post, he always wanted to make a police car himself based on ones he saw in his favourite Manga comics.  As it's illegal to modify a car to look like a police car and drive on the road, Morii-san tried many times to get permission from Aboshi police station headquarters nearby. They refused initially by after they got tired of that they granted him permission. However, the car can only be displayed on private property and obviously can't be registered as long as the police livery is present. The car was completed at a cost of 1.5 million yen (US$ 10,000) in addition to the car cost. A location was chosen outside Hirohata Police box where the car can easily been seen from the street. Morii-san has two other Starion road cars, both widebody GSR-VRs.
