finally got aircon regassed by a mate. It works fine only if I connect the clutch stright to 12V. have tested pressure sensor and that is fine. problem is I push the AC button and turn on fans and nothing happens. I have bridged the 12V from the AC relay plug and if I turn the air fan off the clutch goes off. it seems like the AC button doesnt work but ive swapped it into a mates car and his aircon turns on fine, so far ive swapped the ac amplifier and ac relay, ac fuse, checked as much wiring as I can. would anyone have any ideas? I heard something about teh ecu grounding a wire to allow clutch to work.



this is in a JZA70 with 1JZGTE
