My fan on my 2001 mercury cougar won't come on at all. How can i test it to see if they are working or if i have a bad relay?


This is a partial fan wiring, I'm just trying to show the fuse and relays. That fuse circuit is hot all the time. not only check the fuse, check voltage on fuse circuit, hot all the time, use a test light.
Check for applicable trouble codes, Your coolant temp sensor is involved. On the load side of high-speed relay, the left side in picture, use proper size jumper wire, between the two terminals with relay unplugged, if the fuse is good, voltage, the fan/s should run? If they run, at least the fan motor is working and ground for the fan should be ok. If it runs with jumper, the problem is on control side of relay, either voltage or ground.

1996 Mercury Cougar 3.8 V6 ,,,The rediator fan is not coming on.


So can you jumper the relay to make the fan run?

The computer grounds the relay, so you can jumper the relay and the fan runs, check for a signal from the computer.

Collingfans won't come on after resistor was replaced,also ac pump won't come on, have power to the relays under the hood and when they are jumped can get power to ac unit but still no fans


on the cooling fan part, disconnect the wire harness and run 2 wires from the connector to the battery, ( 1 wire to the pos 1 to the neg) if that dont work, switch the wires at the battery (take the wire on the pos and switch with the neg) if the fan still dont come on , you have a bad motor on the fan. if it does work and your relays are good, i would say you have another electrical problem

Must be electrical problem


Suggest replacing the the switch for the headlights or the switch for the dimmer...doesn't sound like it's your charging system, but more like a switch. There are probably relays involved too, usually in the Fuse Box, that may be suspect.

Good luck,

Where can i find a new alternator wiring harness or (diagram to make one) for a 1985 mercury cougar that has a 5.0 engine. The local area parts/salvage dealers do not have this part.


My software won't let me link the diagram to the internet. So I will describe it to you. I'll use factory
color codes, so if you have any harness left you can
splice to it. On the regulator there's 4 terminals one
ot them is (A) from this a yell/wht wire that go's to a
fusable link then to the + battery side of the solenoid.
The (F) orng/ltblue wire go's to the field terminal on
the alternator.The S or stator wire (wht/blk) go's to
the Stator term on the alt. The I or ign. wire (ltgrn/wht)
go's to the alternator light. (or gauge) Next the B or
battery connection wire (blk/orng) from the alternator
go's to the fusable link, the same one that the yell/wht (A) wire went. Also there is a wht/blk wire
that runs from the stator term. on the alt. to the
choke heater. Hope this helps. Good luck.
