They asked me to leave the car for about 2-3 hours as they will have to check why the fan is not working.

About 2 hrs. i got a call that the car is ready and the total bill is 163 .
I checked with the SA and he said it was just loose wiring which has been fixed, so only labour charged.

So, as of now the problem is solved and yes the AC works even if the car is stand still.

Thanks alot everyone for their help, when i gave my car in today, I already told them that it is not the AC or alternator and they should check the fan... Thanks to Team-BHP.

Be it the Headgasket or the AC , the most common problem is always the simple fan!

In most of the vehicles, the fan starts(albeit at lower speed) when the AC is switched on, irrespective of the speed/rpm.
This is from personal experience. In the Swift petrol if the car is above the 30 - 40 kmph the fan switches off completely and comes back on only when the car slows down. It is not always on.

I also face same problem in my Xing, havent started using the AC in the car yet.

At Gurgaon Toll, we used to sweat waiting in the queue as the AC was tripping and car was hotter than outside temperature. As soon as the car picked up speed, AC was chilling.

But will keep my eyes and ears open on this issue + the response of the fan in such a case.

Thanks for your thread.

It is the fan circuit that is culprit, when it will kick in will depend on the circuit design. Some cars the AC condenser fan switched ON along with AC comp, others are controlled by the grill temperature. That is the only difference.

Almost 1.5K kms later, everything is running fine. Touchwood!

I still think that it was not loose wiring, they just unplugged the battery and thus hard resetting the car.

I understand this but am at a loss to understand how the settings of the car had gotten changed in the first place.

Good to know that everything is working fine. Am just curious would the settings of most Maruti cars be similar (Alto and Esteem in my case) as it would be something for me to be cautious about.

If they had only hard reset the car then the problem would have recurred again as the problem was with the fan wiring.

Edit: Do you have any specific reason to think that it was not just loose wiring?

Hey Vikram,

I am just guessing. Reasong behind this guess is, if it was loose wiring then the fan might not have been spinning at any time which definately would have resulted in over heating the engine which never happened. I drove the car in that condition for about 2 weeks in which atleast 30Km daily in afternoon when temperature was about 35 degrees if not more.

Another reason, MSIL did not sound confident when they had returned the car to me. First they said it was a fuse that was replaced, when i asked for the faulty fuse he took me to the floor supervisor who said.. it was just loose wiring.

Ok I understand your reasons, but like I said earlier that if they had just reset the ECU then the problem would have recurred if the fan was not working properly.

Sometimes the fan keeps on operating even after the engine is switched off and the key is not removed or brought at position 0.
Might be OT-
There is a feature in our Indigo XL Dicor.
Suppose a hot engine is turned off (even after idling for 30 secs. to cool the turbocharger), the radiator fan sometimes keep running for some duration even after remote locking the car. This does not happen always.

And yes this feature is working since the car was purchased in 2007.

My Baleno was diagnosed with the same issue. The AC is very cool when the car is moving and at idling the compressor cuts off. I was told by my car service guy that the fan motor is dead and the price for a new one is 9K(Taiwanese) to 14K(SGP)! Hope its just a wiring thing for me too else no AC for me for a while !!

I suggest people facing this common issue should get their AC fans checked first thing.

If the vehicle is above this set speed then the fan will come on only if the engine is overheating.

Simple way to check if the fan is running is to leave the car idling for 15 - 20 minutes with the AC being off. The fan should run because the car is stationary and the engine is heating up. Then after the fan switches off, switch on the AC. Now the fan should come on. This is the only way of making sure that the fan and all its related components are ok.
Sir, I have a small doubt in my mind. A Ritz Diesel has been my faithful partner since the last 2 years/20000 kms. Over the last 2 years the AC was used for hardly 5-6 times. Now after my father's retirement my drive has changed to the old Alto. Last week when my father was driving the Ritz with the AC on I noticed a few points. Are these symptoms okay for Ritz?

1. Immediately after switching On the AC the radiator fan starts turning. I am not used to the sound, so I feel odd. Is this okay? As you say that the swift has only 1 fan, the Ritz must follow suit too. The fan near the left engine bay starts turning. Is this fine?

2. When the blower fan is turned to speed 4 there is a lot of fan sound inside the cabin. My uncle owns a Dzire and his AC fan is a bit quieter than ours. Is this okay?

3. The cooling is perfectly fine, but do you feel a slight load on the engine when the AC is turned on?

4. Will the AC unit be damaged if I do not use it for a long time?
Thanks in Advance.

Yes. This is perfectly fine. If the fan is not on, then yes the fan will switch on immediately when you switch on the AC.

The fan in blower 4 does make noise. If more, please check the AC filter.

Yes. The Ritz engine does get a little sluggish with the AC on. Especially at low rpm's

Ideally you should be using it at least once a week.
