95 Taurus 3.0 overheating - Relay or fan?

If you have a volt meter, you can measure the voltage at the fan terminals. If you have 12 volts and it does not spin, its the fan. If you don't have 12 volts (when hot of course), its the CCRM relay module or a computer issue. You need to see where there is voltage and where there is not.

Okay - first off, thanks for the advice. Now, more of my ignorance.

I got my car heated up today, and pulled out a voltmeter. First connection I checked got 14 volts, so I plugged it in. Viola! The fan worked! Yay, right? No - now I can't figure out why it's working again! I left the car running - it would heat up, then the fan would kick in, just like it's supossed to. Now I want to know WHY!!

Any ideas? Loose connection? Dirt? In this picture, the lead plugs into a box (the fan relay?), which in turn plugs into the fan. This 'box' was pretty hot - but then again, considering it's location, maybe it should be expected to be hot.

Anyhow - count myself lucky, keep an eye on the car, and go about my merry way?

I hate not having an answer as to why it works now.

Thanks again, for the advice and help, folks.

Look close at contacts... high current corrosion.... much like battery terminals

Simple fix, plug/unplug several times, then get dielectric grease and coat contacts liberally.

If air cant get to it, wont corrode.
