All you have to do to turn the fan on is to unplug that sensor and the fan will turn right on. You don't need that paper clip to turn the fan on.
I'm wondering if the CTS worked for you? My son's car is having the same problems. We replaced the thermostat, radiator, alternator & water pump in Nov. The other day, his car overheated. I determined the fan was not coming on. I have checked the fan with the AC on & off. It dosen't do anything. We replaced the fan motor today, still nothing. It sounds like you are having the exact same issue. I'm also in Texas & need to get this fixed soon.
you need a coolant temp sensor my friend..
the reason for the paperclip is that you are actually telling the computer the car is
running at 300 degrees..it is obviously NOT the computer otherwise it wouldnt have turned on.. trust me c.t.s is your problem..
dont get it from autozone, for 2 more dollars get one from napa..
everything should work properly after its installed..
my 2000 wire harness only has two wires coming out but three posts on the terminal, one just goes into a dead hole on harness. I have probed the wires at fan plug in and it still wont come on, I've also jumped at the cts and nothing. On mine the cts is plumbed into a union and into the block, kind of weird cause its not like any I've seen.the fan is controlled through the ecm which sends power to the relay to turn the fan on. the ecm takes the signal from the coolant temp sensor to know what temp the fan needs to come on at.
by jumping the plug to the c.t.s. with a cotter pin, basically tells the ecm
its at full temperature.......if it will not turn the fan on, use a test light at the plug to the fan to see if it is getting power...if it is it would be between the plug and
the fan, if not you have to work backwards and check fan, relay, ecm, cts,...
the most common problem ford had was the plug connection to the fan itself.
that is why they recalled, for a fan resistor install between the plug to the fan and harness..why? because the fan plug was melting, overheating, causing the three wires encased in the fan plug to melt the plastic that seperates the 3 wires.
causing the ground wire and the power wire to touch.. result ..fan inoperative..
it is highly misdiagnosed because you cant see the melted parts of the plastic until you actually unclip the plug and look into it.
i have replaced quite a few fan assy.. since they started having this problem in
1994..
