[QUOTE="MG0h3, post: 16901836, member: 164690"] Def buy a multimeter. Doubtful that you have a shorted wire. If a power wire shorts to ground, fuse blows. If a ground shorts to power (very unlikely) fuse blows. As mentioned, all the 02 codes would have me checking the work around the exhaust. Not sure that would cause a total shutdown though. But you already checked there and didn’t come up with anything. I suspect the AC issue was isolated and while you fixed the clutch issue, can’t comment on why it isn’t blowing cold. Confirm that your battery connections and grounds are good before going too far down the rabbit hole. Buddy at work had intermittent dying that started after he installed an inverter which was wired to the batt terminals. I was able to wiggle the ground terminal off. He would get every light on the dash, then dead. He could randomly get it going again after sitting for a few minutes. Every now and then someone will have strange problems like this and reloading the tune will fix it. Make sure the batt terminals and grounds are good first.
