Hello everyone, I got a problem where the electric radiator fans on my 2004 RX 330 with 224K will not come on for some reason. I first noticed it when the AC stopped working and I’ve had this problem before with an Avalon that has the same drivetrain. So I replaced the fan assembly thinking that would take care of it but no dice. The fuse is good, and I’m pretty sure the (integrated) relay is good because there’s power at the connector going into the fan module. There’s also power coming out of the fan module into the two fan connectors as well. Hot wired the fans to make sure the motors work and no problem there. It’s like the command to turn them on isnt working so I replaced the coolant temp sensor, but that didn’t do anything either. Traced back anll the wiring from everything and it all looks to be intact. Other than that, all of the HVAC controls and actuators work, but the AC compressor doesn’t engage. No check engine lights nor anything else like that on the dash.

And the funny thing is that it doesn’t overheat. Been driving it every day in South Florida for the past couple weeks and the gauge doesn’t go past halfway.

I’m really stumped any help would be appreciated. Thanks!
