Cooling Fan Runs All The Time on 2005 Lincoln LS

Hi, soon after starting my Lincoln LS Sport the cooling fan runs at high speed and is loud. I replaced the cooling fan as I thought that might be the problem. But the fan still runs at full speed and is loud and very noisey. The temp is the half point on the gauge. I am not rich and I was hoping you might have heard about this from some one else, so I might have a better idea on where to look next. Thanks, Bob

There's probably a relay or maybe 2 relays controlling the fans. If the relays are stuck on, the fans could possibly run with the ignition switched off. there could also be a problem with the control system. This kind of thing is common enough, it's not unique to Lincolns so use your logic and diagnose the system using a meter or take it to a Lincoln specialist and get a diagnosis and estimate.
