Aren't Zetecs a "one-fan" car? duel speeds but one physical fan?
You're looking for the low-speed fan relay, is what I am assuming.
Oh.. and.. rather than just patching around a problem, you should probably attempt to determine WHY it isn't working.

no my 98 has two fans and one is low and one is high. i took the thing to the shop and thay had no clue as to why it was not coming on. thay could hook up there test stuff and make it come on by comand. thay said it could be anything. thay tested all sensors to not to mention i already replaced all of them with no change.so the next best thing is to bypass them and run it to a switch. got any idea. what to try other than the switch?

Seems I just pointed out recently to someone that the fans are wired in parallel.
That means, there is NO LOW SPEED FAN.
Both fans should operate at the same time and at the same speed.
Have you checked the low speed fan resistor and relay???

Try this link Fan circuit topic It will help you. There is a schematic on page 2.

From Terry, cooling fans are two, two-speed fans. If you look at the circuits when in low speed mode BOTH fans are fed Via the resistor and BOTH go at the slow speed. At high speed BOTH are fed without the resistor in the circuit. Neither is high or low. They are both high & low due to the wiring of the feed. Same goes for the early Zetec single fan...it is two speed due to the resistor in the circuit....to prove it out,if you wish,put a volt meter on each fan feed at low speed BOTH will show reduced voltage
via resistor...turn on the AC and BOTH will read battery volts...

ok i tested the 3and 5 pin on each relay and both fans work does that mean the pcm is not sending the signal to turn them on .

Might have bad ECT sensor. Pretty easy to swap out. About $15.
