Thinking about getting this 97

Somi jimmy-rigged some wires and ram it toy battery. Nothing happened. Are my wires connected to the proper terminals?

Using the pigtail as a guide, the left wire (bottom) has a red stripe so I gather that's positive, middle is blue, so signal, and black is black. Is my thinking correct here?

If my thinking is correct, then this is correct, right? Positive on bottom and negative on top.

If those are wired to the battery and it’s not running your fan motor is cooked.

Have the one from the pearl car handy?
 
Ground is black, blue is low speed, brown/orange is high speed. 16 gauge is woefully inadequate but it should still spin it for a little while for testing.

The fan is two bolts, I’m not trying to turn pearl into a parts car but it might get you out of a jam 😆

So if I plug into the blue, it should work better due to lesser voltage requirements?

Gonna try that next too.

Also, what happens if I put car on ACC mode with AC settings turned on? Should the fan work then?

AC will turn the fan on IF the fan works

It’s not a matter of voltage requirements, if you run the fan off the battery with inadequate wire the fan will still run, the wire will just get hot as shit. The motor simply taps the coil at different points, so if there’s an open between high and low it’ll run in low, if there’s an open between low and ground the motor is dead
 
So here's what I just found out:

When connected to the black/red port (bottom) on the fan port, nothing happened. When I plugged into the blue port, I got a spark and wire got hot AF. Got the burn mark to prove it! 😂

Trying to find a blue spade connector to try again using 12ga wire now but I'm striking out in that department right now.

So AC on high setting should turn on the fan?
 
This ought to work, right? 12ga romex cable?

But again, what ports to unplug into? White will be my positive side with this get up.

But his question was if this happens in Accessory mode. Which would be a no. Even if you turn the key on (ignition on), engine off, and A/C set to on, would the fan come on? I would think that only applies with engine running (?).

Accessory no, but KOEO/A/C it should run the fan in that scenario.

Question: did the fan run and then the wire get hot or did the wire get hot without moving the blade? If the latter that points to the motor bearings being seized rather than an open, if so that implies the fuse is probably blown too

It all happened fast, so I'm not sure. The fan does spin freely by hand though, not sure if that matters any.

If it's a fuse issue, where is the fuse box I need to get into?

I just tried the romex cable with the white connected to where the black/red wire goes to and nothing. I'm about to try with the white wire connecting to where the blue wire connects to.
 
Update:

Tapped into the blue wire, the fan spins! The fan bearings also sound like absolute shit, lol.

Yes, KOEO. And yes, for extended periods of time, it will drain the battery.

I have a habit of turning the HVAC dial to OFF before turning on the ignition...so I can't say for certain, but I don't really believe this is true.

I'm sure that on the odd occasion, I have turned on the ignition with the HVAC dial on A/C, MAX A/C, PANEL/FLOOR, FLOOR/DEF, or DEFROST, and I did not hear the fan come on.
 
And I'll set my HVAC to "panel" so AC isn't on when the car is off, lol

Also, I checked the owner's manual, and I didn't see anything there about the fan. Is it tied into the AC system?

Yes, it is. It's in the workshop manual, but it's too late now for me to get up and read the exact verbiage. I think it says something to the effect that the fan is always on when the A/C is on and the speed is below 45 mph.

But my point was, I could swear that only applies when the engine is running. I could be wrong though...
 
I still want to know what / where to plug the fan connectors into to verify the fan works.

That question never got answered.

Didn't your car come with the original owner guide? Those diagrams are in there.

It did, lol. But like the website I linked, it doesn't have a fuse specifically for the fan. That's what I was hoping I'd find.

Also, I'm seeing conflicting information; is it CCRM or ICRM?

Bearings aside, what else is the giveaway here?

Mainly that, even if it does spin it's only a matter of time.
You also jumped power to the high side and it did not spin. So your fan has no high speed function, when low ain't good enough you've got nothing. That's worse than low being insufficient.
There's a slight chance there are other problems, but your fan is definitely one of them.
