hey guys ive looked everywhere on this forum for help but just cant seem to find out whats going on.. i have a 2005 evo 8, my ac just stopped working completely, as in no power at all , it doesnt kick on at all. need help asap

Ive heard it could be the air sensor on the center-right vent?

I had this issue. It was the large green fuse in the inside fusebox. The contacts for the fuse melted.

fuses, relays, check R134a level then check your compressor clutch air gap

checked out all fluids as well as compression. also checked the relays and fuses. Ive had it for 2 weeks so im new to the evo! I wonder why these cars have so many AC fuses/Relays?..
The fuses under the dash/hood were all good

Anything more than fuses and relays will probably require an inspection from a shop.
Have you tried to manually turn the compressor on by bypassing the relay? How did you check the pressure in the system?
That could give you a good place to start for diagnosing.

my buddie had checked it at his shop... he said it was most likely an electrical problem, But i had someone else tell me it could be a sensor that burns out near the air vents?

When you turn the ac on does the fan kick on as well as the compressor? You say no air blowing inside the cab at all? Not even hot? If youre getting hot air try some 134a

theres absolutely no power to the AC/Heater console it self... like when you push in the button for ac or the any of the 3 options the green light does not turn on, so nothing works

did you change any of the relays around? Sometimes relays goes bad without any physical appearance change. you may try changing the AC relay with another one thats the same under the hood and see what happens. Sounds stupid but its happened lol

If not a fuse/relay problem then its definitely an electrical issue whether it be a loose ground or cut/worn wire. I can't think of anything else on the AC system that would cause it to completely not respond unless the switch/button you are pushing has went bad.
