It could be a relay indeed, and they can fail after some years easily...
Just change it for another one to be sure...

Thanks peter

I checked the position according to the handbook but there is a 40 A fuse instead of relay

Am i misunderstanding something or relay should be somewhere nearby?
Checked everywhere

Relays are small square boxes, right?


Any pointers where a relay for engine cooling fan is will be very helpful

It may vary from model to model, and country of manufacturing.
Maybe ePER on top of this page is helpful?
At our Palio, the relays are right next to the battery, a few are next to the fuses inside the car.

If you dont mind, whenever possible can you share a picture of your car whenever possible of the location where all relays are

In my car first there is set of 4 fuses where one of them is ignition. Next slightly below is engine cooling fan fuse with abs fuse. My car does not have ABS so no fuse there

Last is number of fuses covered by a big box

Also read the following on another fiat forum


"Couple of weeks before, my palio started to boil. This happens in city driving in 2nd and 3rd gear. if I switch on the AC, the heating problem goes off.
So what happens to the palio to over heat when the AC is off.

Palio radiator fan has 2 speed. Low speed when the AC is switched on. High speed when the temperature crosses half the mark on the temperature gauge. These 2 speed is achieved through a regulator switch sits at the bottom of the fan.

High speed is governed by the ECU. And the low speed is governed by the AC switch.

The ECU switches on the high speed fan through a 50 ampere relay. If the relay is fault, radiator high speed wont work. but the AC low speed mode will work.

The AC low speed is controlled by the 30 ampere relay. While the AC is on, and the ECU switches the high speed mode, this 30 amp relay will go off.

All these relays are present in the relay box under the battery."

Are you talking about same position . If not need to check underneath the battery

Not under the battery!
Right behind the battery is a black cover, secured by two bolts, take it of, and you'll see the relays.
Again, next to the fuses inside the car are relays as well, I don't know which one is for the fan though...

okay
i got the location where you are pointing at

Had opened it up as well, but am not sure which relay for engine fan

Fuse box inside car has a relay which control functions like horn, central locking


Let me check with local guys here and hope i can get info which relay is for engine fan

basically i just want to make sure its not a relay issue before sending to the workshop

Okay, any way to find if relay has gone bad?

Any physical signs which can determine bad relay?


Thank you so much for the assistance peter

You can't judge a relay from the outside, it has to be tested by an expert, I'm afraid.

I could locate another black colored box which i feel has all the relays for fan

Its ahead of the battery but sits just before from where the battery is

I mean base level of battery and this fuse box is same, its situated ahead of the battery

Will click a picture tomorrow and post

Could not open it today. Hopefully will check it out tomorrow

A gentleman who has a palio helped me solve the issue (almost)

According to him 99 percent its the fan resistor but has advised me to change the relay as well as it does not cost much

One symptom from which one know the fan resistor is not working is that when we switch on Air conditioning, the low speed fan comes on and after sometime the high speed

In my car, even after compressor kicks in the usual fan hum is not there and after maybe be 30 seconds the high speed fan is activated

Hopefully should get the parts within a week

Only thing i have to make sure is that to check if the housing in which the resistor is plugged in is burnt or not. If it is, will have to change that as well

Fingers crossed

Total turn of events

I had removed the thermostat connector and refiited it. That made it fit properly and the lower speed fan started working as it should
Low speed fan starts when engine temp is nearing 50 percent, cools the engine down and shuts off

I was getting no engine check light but when i removed completely i did. So i guess this bit is solved and I think I know what caused the issue

I had given my car for service and cleaning. Had strictly told them not to clean engine bay with water blast but had not refused cleaning with air.
I think its time to say no for that too

Upon close inspection I found that all connector bodies have become very brittle. When i removed the thermostat connector the lock broke, so one can imagine how brittle how it has become. Luckily the connector fitted back tightly

Not sure if only connectors can be changed. Also the protection covering on all wires has started cracking and coming off. This exposes runs of wires and if any of them get cut, it will be a big problem


Also, the high speed fan stays on even after turning the AC off. will have to connect a scanner and check if there is any error code or it could be a problem with high speed fan relay

Left side low beam headlight also not working which i think is the same issue of connector due to the blast of air used to clean the engine bay

Lastly, one wiper not working and intermediate speed not working. Need to get it rectified before rains start

Too many niggling problems with the car

In my workshop, hanging on the wall, I have a metal sign saying:


"If it has tits or wheels, it will give you problems".....

Hahaha haha

But it's really true and fact of life

Works been hectic. Will let it get over and with a free mind will get all problems rectified one by one

Hi Peter

The small wiper linkage has gone bad and i need to change the whole wiper linkage since it comes in a set

While I was on it, I thought why not even solve the intermediate speed setting not working.

Any idea if the speed is governed by the motor or some other device connected to the motor?

When i am asking mechanics over here, they suggest me to change the motor first and then see how it goes

I don't want to experiment as once i purchase a part, no retailer will take it back

Some years ago, I replaced the wiper motor on my Fiorino Pick-Up, everything was in that motor, speed, interval etc.
Don't know about the Palio, though...

Thanks peter

One very well informed gentleman also confirmed everything is part of motor inpalio

I am getting motor with linkage for approx 30 USD extra

I think its worth changing everything (linkage and whole motor assembly)

Keep us updated, if you will.

Surely Peter

As and when i get time will go to see the guy who sells the stuff.
In max 4 to 5 days

Sorry for not updating the thread since long

Not been able to take out time to go to the retailer and get the required parts.
Have set priority to do it by next week

Then will update the thread

Hi Peter and others

After a long wait finally ordered the wiper linkages.
I actually ordered the whole set i.e. wiper linkages with motor.
I had suspected something was wrong with the motor, not actual motor but the small white controller which is sort of a part of motor

The wipers when turned off stopped immediately rather then going to the lowest position and then stopping. I hope along with this the intermediate speed not working is also solved

Cant afford to change the switch gear as of now which seems the next culprit if not solves by changing motor

Fingers crossed

Part should reach me by monday. will update the thread once installation is done

Finally installed the wiper linkages and motor
There were some issues like a broken bracket of plastic cover on top of linkages
As of now its fitted being little loose from where bracket is missing

Also i saw some rusting where the linkages snd motor is housed. As everything was already removed so got it painted so rust stays in check. I know should have done.some proper treatment but i guess this should be good for few years

Only issues remaining are rusted muffler whuch i will get changed by next week and some ac water coming from the footwell

I am not really sure what causes this and what should i do

Is it a quick fix or need to go to ac specialist?

AC water should flow from a black hose, against the firewall, behind the engine.
