hi i have a 2002 taurus the radiator fans will not come on i changed both temp sensors checked fans and relays witch are good any thoughts thank you not even when the ac is on
Year : 2002Make : FordModel: taurusEngine: 3.0 12 valve
both temp sensors checked relays and fans they are good
I would recommend to check for power going into both the high and low speed fan relays. I believe power comes into these relays via red wire. If there is power to these relays, I would recommend to check to see if these relays activate and power up the fans by grounding the light green and violet wire coming into the relays from the computer.
tried that fans work replaced relays and the still do not come on not even when ac is on
DOes the fan relay relays have power to them with the key on?
yes they do
Do they engage or click when you turn the AC on?
SO if this is the case, then we simply have a break in the wiring from the relay to the fans.
DO you need a diagram?
there are two wires in the plug that go to the coolant temp sensor is one supposed to be live
I believe one if them should have 5 volts.
what do think the chances are that tha computer is the problem
If the relays are clicking, then the computer is good.
Did you have any further questions?
Would you like a wiring diagram?
Does this make sense? If not, please let me know.
yes you mentioned a diagram is it possible to see it
Here you go.
all my other cars if you unplug the temp senser the fans come on should they in this car also
YEs... I believe so. But I am not positive.
would a bad cooling fan resister shut down the fans
YES... I do believe its possible!
