I have replaced all three fan relays on my 2004 impala. Fans still do not come on. I put voltage directly on fans and they will run. What else could be wrong?

They should only come on if engine temp gets to high or if ac is turned on at an idle.

Did you check the cooling fan main fuse? Check damaged wiring or connectors.

The radiator could be stopped up not letting sensor read correctly. With A digital thermometer you can che k temp of top hose and lower hose at running temp. If not drastically different no blockage.
