2007 RX400H, 160K MILES
Battery replaced over the winter and just getting back on the road. Three codes P0A84, P0A99, P0AD2.
Control circuit low on all three fans. Don't believe I replaced the fans with the used battery but not sure. Old battery rusted out from drain stopping up and flooding the battery box. FANS WERE DRY AND SPUN FREE. Been looking for info, wiring diagrams, on the fans and where they get their current and ground to work, what controls them.
Please help. I'm at my wits end and if gas wasn't so expensive this car would be gone.
A little bit, I am an ase master tech retired after 35 years. Like electronics but without diagrams it's almost impossible for me to diagnose this car.

G9230-48010 is about $100 online, there are 3 fans do any of them spin? I would be more inclined to think one or more thermistor is not connected or working (there are 3). You're going to need at least the factory service manual and possibly Techstream. For $20 you can download the service manual.

All the fans spin, all the connections are plugged in and as far as I can tell the pins are not damaged. Wish I had identafix but it's just too expensive. I dont even have the internet so it's all on my phones data plan.
