Fans won't turn off even when the car is off
Hello, I just purchased a 2008 RDX for my wife and of course everything worked fine until we got home.
I replaced the 30A fuse under the hood and it stays on. After 2 hours I had to remove the fuse so the battery doesn't die.
I hope this is not an ongoing problem or the start of worse things to come. We have had such a hard way the last few years so any advice is appreciated.

Do you know what it could be?

Are both the ac fan and radiator fan staying on?
The fans are controlled by the PCM via two seperate relays which are housed under the hood-fuse/relay box right next to the brake fluid reservoir on your car.
It is common where the relays on any make and model can fail and the contacts inside can stick in closed position (feeding constant power to fan/s).
Take the relay out and temporarily swap it with another 4-prong relay to check if the fan stay on/off. You can use the rear window defogger relay for your test which also happens to be a 4-prong relay housed in the same box.
Let us know how the test goes.
