Amazing to be posting here for my first time, since I've read so many posts on this great website over the years. Wonderful community, and I hope somebody knows how to help.
My 2004 Pontiac Vibe's AC is blowing warm air. My dad was driving it (I wasn't in the car) and he told me it made a sound like it was stalling out, then it came back, and the air was warm. I have read many threads on here about this issue, so I confirmed that the compressor clutch is not engaging (although the engine does make a different sound when the AC button is pushed) but it is able to turn (not super freely but it does turn by hand). I tried to "jump" the relay by following instructions in posts such as this, first with a paperclip between the jacks from the fuse to the clutch, and when that didn't work, I went out and bought a multimeter which confirmed there was no power coming in (I tested every combination of holes, then tested the cable that runs into the compressor).
I thought this meant I was fortunate enough to simply have a blown fuse, but my A/C fuse in the interior fuse box was perfectly fine (swapped it out just in case but it made no difference). Furtheremore, I then ran a piece of wire straight from the battery's red terminal to the jack for the clutch, and it still didn't initiate. Maybe I did it incorrectly?
So now I'm worried I have an electrical problem and a bad clutch I'm not sure what to do next. I would be more than willing to install a new clutch but I have no idea how to start tackling the electrical problem.
