I have an issue with 570/1000. The PS fan is coming on whenever the battery is connected (key on or off, doesn't matter, or the storage disconnect active or inactive). The low speed circuit is utilized for the PS fan. I did not have an issue with it until I removed the fusible link box off the positive battery terminal. I moved the power seatbelts to an empty sub-fusible link spot that was unused, and the other was just a single 8 ga (ish) wire on a ring terminal going to the storage connector. The relays still function on/off as they should being triggered by the fan switch and A/C coolant temp switch. I removed EVERYTHING from the fuse box (relays, fuses and fusible links), disconnected the 2 grounds in the engine bay (2 and 4 as per the FSM), disconnected the A/C switch and temperature gauge sensor (thinking I may have mixed them up), and even tried hooking up the stock fan. The stock fan won't work on low-speed, works on high-speed, but also does not come on when only plugged in (possibly un-related?) It acts like a short, but I wanted to see if I could get some feedback on if I moved my wiring correctly, or if I'm causing a loop. The fan does not change speed when the low speed relay is energized. I checked the DS plug as well, and the same situation is occurring there as well.


The wire circled in red is of suspicion.


This is where I put it (I think). Now thinking back to it, I don't see why I would need it, but I also don't see it causing this issue with the fans. I've spent around 4 hours trying to diagnose this myself and now I'm reaching out for help. I have access to FSM's, but struggle to really understand the wiring diagrams (obviously). I've been using only a multi-meter for this, but if I need a test-light, I'll gladly grab one if it will help with diagnosis.
