No cooling fan 2008 g5

Hi all, recently replaced my motor in my 2008 g5. Timing chain went on the old one. Got it running yesterday and all is well but I've noticed I have no cooling fan. Relays and fuses are fine, car reached 230F and still no fan. Unplugged the fan and I have 12 volts on all 3 wires? Shouldn't the black wire be a ground according to the wiring diagrams?
Please help! I'm almost back to driving my car!

what engine 2.2 or 2.4 and yes theres 2 powers (low and high) and 1 ground - if you have access to a scan tool to command the fans on for speed 1 and 2 and make sure a test light lights up at the fan connector for both and make sure you have ground then the fan will require replacement for the le5 (2.4) engine the fan ground is located on the engine block below the alternator and for the l61 (2.2) engine is located in the same spot

Sorry it's a 2.2 and I understand how the fan is supposed to work with the 2 power wires. But the black wire (ground) on the connector has 12v to it? My fans probably fine it just doesn't have a ground to use because that wire has 12 volts on it

well you shouldnt have power on that wire meaning its shorted to power so either trace the wire and make sure it didn't get pinched somewhere or just run a new ground - does your car have a air pump? because the ground would share that also and if so i dont know if you removed the fuse block or anything but it could be back feeding on the ground circuit through the fuse block

Thanks so much for letting me know the location of the fan ground strap. I think me and my dad accidentally hooked that ground up to the positive output of the alternator. That would explain why I had 14 volts on the ground wire with car running, and 12 volts on the ground wire with car shut off

Pretty confident we just hooked it up to the wrong place. Working out of town this week so won't be able to touch it till next weekend. But all in all the engine swap turned out not bad, no engine codes, cars running well minus the fan. But I'll take one little human error over a handful of other mechanical issues or bad sensors and what not. Thanks again
