AC Noise

Whenever I start the AC Fan there is noise as if there is some paper stuck in the airflow (fluttering noise). I have shown it to service engineer and he says there is nothing wrong. Has anybody faced similar problem?

Solution?

I was just joking..

It is a possibility though.

It could be some leaf stuck somewhere.

The service advisor is not able to hear the flutter?

leaves !!

Yes. There is a possibility of a leaf getting stuck in the vents. I stil have one in my system coz the service advisor doesnt seem to be able to hear it fluttering. on speed 1 & 2 the blower is fine. But on 3 & 4 . I dont turn it to 3 & 4

Probably have to fix it myslef now.

I would just Leaf it

The logan is a good car for everything.For Eg:Comfort, Style, Space, Fuel Efficiency, boot Space. The best features for a car called Logan made in the world.But for one majoe issue which the car man ufatcure had taken care off.the problem not I but each & every logan buyer is facing & the problem is about the Driving Mirrors.Once Opened they cannot be closed.This is nonsense at this is the best needed because in a country like india where the roads are narrow, gullies the mirror has to be closed.if closed the mirror gets breake.it is necessity as it is very Imp part of driving.In that case the Logan manu must recall all the logan sold to rectify the problem as this is a very major issue because of which logan sales are falling down.Renault is a good company & never expected a company to ignire such a small mistake.The other models form Renault are Fluence is a good car, but in india no doubt how the car is perfect no one cares if the company is not bother to fix it.

1. The issue has been addressed with the new mirrors now provided on Logan
Earlier design mirrors were common throughout-globally. Hence they never saw the need to change it.
2. I dont see the need for a recall just to replace mirrors (It doesn't jeopardize the lives of occupants or pedestrians). Its just the design of the mirror
3. Sales falling due to poor mirror design??? I didn't know that.

No Rats. No Paper.

However as soon as i put the A.C. on i get to listen to some noise from engine as if the A.C. is overloading engine. So far there was no noise as such, but now there is a very low noise as if some metal part is rubbing against each other. This is more evident outside the cabin.
If you can recall the vibrating noise that comes from Window Air Conditioners or vibrating noise that comes from Fridge Compressor. I get the same.

However ride remains same as earlier and engine power is also the same.

Is there anything i can check or will have to get it checked with service center.

My car too has similar problem as what vsuprak's car has, that is A/C blower motor makes more noise on switch position 3 & 4. One can feel the judder on the cars dashboard. It is fine on fan speed 1 - 2. This was not there during last summer season and is being noticed now in this season. During winters fan speed 1 was being used so it was not noticed earlier. I would like to know if Yogi73 too is facing the same problem of huge noise when fan speed motor is on 3 - 4 and it is fine on speed 1-2.

Air Bubble in the system maybe (only my thoughts here) can you get the AC bled ?

Even when the a/c is switched on or put of, the fan motor makes noise at position 3 and 4. The problem most likely is with fan motor or maybe, kind of blowing impellers being imbalanced. It is fluttering noise and vibration is felt.

Ahhhhh Leaves °!!!! it will be leaves in the ducts

In my last service, the problem of the noise was sorted out.
I made it clear to the service guys that the issue was left unattended in the previous service.
This time however, they could set it right. They didn't quite tell me what the reason was, but i believe it got something to do with the alignment of the blower fan (my guess)

I faced a smilar problem and got it checked. There was a twig in the system and the noise was proinent in 3&4 speeds, while it was there but with lesser sound at lower speeds. It was a 10 minute job and they got it cleaned by accessing it from the area below the wipers under the hood.
