The cooling fans on this 2014 Sienna do not engage as needed. I replaced the control module but the problem persists. The lead in the attached image is getting 12 volts as indicated. I tried to start the fans with a direct hit from the battery but they didn’t kick in. I would appreciate any suggestions for a valid test to track down the problem. ![Capture](https://global.discourse-cdn.com/cartalk/original/3X/5/d/5d7595bc9c7db8f34b4c601685452a735266c0fe.jpeg) ---

If a 12V jump didn’t do it, replace the motor ---

The two connectors in the back ground go directly to the motors, did you apply power and ground to those connectors? ---

Yes, I ran power and ground directly to the fans - - neither work. I was bewildered because neither worked thinking why would both go bad simultaneously. But I am not a wizard at an issue like this. I really appreciate the responses. ---

I ordered new fans. Do I remove the old ones from the top or bottom? I haven’t been able to locate any instructions on replacing them. ---

OP is talking about the fans at the radiator, not the one.in the cabin.
