Hi everybody, im havin a slight problem with my cooling fan, i dont think its workin like it should. My car seems to be running hot and it has overheated once. When i let the car idle with ac on full the fan only comes on for a sec and shuts off quickly same with the ac off ! help please

ps the fan motor is fine and its a 95 contour thnx again
Welcome. . FavoriteMystaque is our radiator fan/cooling resident expert. I am sure he will post some suggestions when he sees this.
I don't have any wild ideas but first, is the coolant at the correct mix? 50/50 is nominal, for -20 deg F.

And when was the t-stat changed last?
Does it low speed fan spin freely? If not, the brush rigging has melted like many other 95s. I had fan rigs replaced on both my 95s under the recall.
yes the motor is good, the fan will come on for just a sec then it turns off and it spins freely!
I had the same problem with my Contour. I bought new relays and it worked for a few hours then stopped. I ended up bypassing the relays and now the fan will stay on, when the car is running, all the time, which is fine. The car never overheats anymore and it reaches operating temp. If the fan burns out I'll just buy a new one.
I fought this problem for three years on my 95 mystique. I finally wired in a manual switch, via a relay, to the fan. The switch is mounted in the dash, so I can turn it on whenever I need cooling, and turn it off the rest of the time. The problem now is to keep my eye on the gauge, and remember to turn it on when it needs it. When summer time arrives, I'll just turn it on and leave it on whenever the car is running.
so do you think its the relays?
I never did figure out the problem. I had a lot of work done on the wiring harness, and I replaced relays and sensors on a couple of occasions. The thing had a mind of its own. It worked when it wanted to, and not when it didn't want to. About the only thing I didn't replace was the computer. I finally just gave up on trying to get it fixed, and wired around all of the controls.

Does it come on when you turn the A/C on?
Mine is now totally manual. It always runs when I turn the switch on, and it never runs when the switch is off. It is totally independent of the a/c. It's not really a good situation, but it's better than it not working at all. At least, now I am in control.
it dosent come on when i turn the ac on it just sits there Im really bothered that it will overheat
The cooling fan"expert" is here Probably, the low speed circuit has failed. Remove the 2 relays, key off. If you jump 3-5 on the green relay's socket,the fan should run low speed. Then jump 3-5 on the black high speed relay's socket the fan should run high. If the 2 speeds work, with strong airflow then the fan circuit/resistor is OK. (You could pull the ECT sensor plug, see if the fan comes on and stays on. That will set the CEL light.) The Pin 7 of low speed relay goes to PCM (Powertrain Control Module) which triggers the relay, and could be a wiring problem there. The a/c should trigger the fan after a short delay. Fan first, compressor next is how mine (V6) works. If the fan does not work, the a/c will overpressure shortly, turn a/c off asap. Here is a V6 schematic, the Zetec is the same, 1 fan motor instead.

LOL. . Welcome back!
Ok i jumped the two and the high speed fan works, low speed had no power, so now im not sure what to do any advice?
get a new cooling fan

The fans are wired in parallel. They should both operate at the same time at the same speed. Observe the splice designation (S44) on the drawing.

If only one works, the the other either has lost its power or the motor has failed.

I'd suspect the low speed dropping resistor is open. Check it with a meter.

I dont think buyin cooling fan would help since the one in it works fine its just not getting power from the slow speed circuit, lke it is from the high speed. I need to figuire out how to fix the slow speed circuit!!!! this car is getting frustrating!!!

It's always frustrating when you don't follow directions.

Test the resistor. Replace if open. Very common.

Steve

Im sorry, thnx for the help but where is the resistor (what does it look like) and how do i test it? Im far from an auto mechanic as you might of already guessed?

You have already tested it and it doesn't work.

Radiator fan resistor located at bottom left (driver's side) corner of the fan shroud. According to the Ford CD manual, you need to remove the fan shroud assembly to access it.

Edit. If you are up to it, here are the instructions from the Ford CD Manual.

Cooling Fan Resistor
Removal and Installation
1. Remove cooling fan motor/fan blade/fan shroud assembly as outlined.
2. Disconnect wiring harness connector from the cooling fan resistor.
3. Remove cooling fan resistor retaining screws and resistor from fan shroud.
4. To install, reverse Removal procedure. Tighten retaining screws securely.


Cooling Fan Motor, Fan Blade and Fan Shroud Assembly, Electrical
WARNING:
TO AVOID THE POSSIBILITY OF PERSONAL INJURY OR DAMAGE TO THE VEHICLE, DO NOT OPERATE THE ENGINE WITH THE HOOD OPEN UNTIL THE FAN BLADE HAS BEEN FIRST EXAMINED FOR POSSIBLE CRACKS AND SEPARATION.

Removal
1. Drain engine cooling system as outlined.

2. Disconnect battery ground cable.

3. On 2.5L engine equipped vehicles, disconnect wiring harness connector from A/C cycling switch.

4. Remove main wiring harness retaining push pin from fan shroud and disconnect main wiring harness from retainer brackets located at top of fan shroud.

Note:

The two (on my '95) fan shroud bolts have square heads that slip sideways into the radiator mount pockets. And are those fun to remove after rusting up!
my cooling fan has started to make a squeeking noise. Ford wants $255.00 for a new one. I got one on Ebay for $70.00. It's a new after market one. I hope it is a good one.
Did you fix the fan, your low speed resistor is likely bad, or a bad wire goes to it.
I am goin o try it this weekend i wanna say thank you guys for all your time and help it is greatly appreciated, thnx for exlaining in detail also i know that mst of took time to type so thank you very much : )
p.s. i will let you know how it goes!
You're welcome
