I asked him to thoroughly check the electrical system running towards the blower to make sure the new one doesnt blow out as well, he checked it and said all is fine. This issue could very well be due to the Tata guys emptying a can of some ac cleaner in the central ac vents which blew off my steering controls and audio system this year in march. The mechanic said the blower went off due to some liquid.

I dont think thats the case, if you dont fiddle with compressor or condensor etc then there is no reason to refill gas. The AC after blower replacement is as effective as it was and really chills the cabin in no time.

It is definitely not chilling as it used to be, even in the September weather, I would sometime go up as high as 4 to get the cabin cooled, where earlier even 1 was effective. In my 800, I could look at the compressor and near it would be a can with a little look through glass and if there where bubbles swirling in this, it meant that the refrigerant was low. I am not able to see this little can like thing in the DDiS engine bay.

My Palio AC suddenly stopped working. The blower doesn't start and there is no cooling too. I read above that fuse could have blown out. Can anyone help me find the fuse?
Are there any good AC shops between HSR LAYOUT and WHITEFIELD in bangalore?

Hi,

The niggles threads for the Octavia are legendary. Almost every part failure seems to have been covered by someone or the other. From ugly DSG failures to faulty airbags the forum seems to have it all. Well, thankfully I haven't encountered any of those issues yet but something else popped up. Since I couldn't find anything on it I decided to start a thread on this.

The problem started whenever the AC dial was set up to 3 or above. An audible humming sound emanated and the blower stopped blowing air. It sounded like something was obstructing the motor. Upon increasing the air speed, the sound just got more audible without any air being blown. Initially I would just reduce the airspeed to 1 or 2 and the blower would continue to blow cold air without sound. But after continuing like this for a few weeks, the problem has now started even at low fan speeds. I got this checked at the service centre JMD charkop, Mumbai and they said the blower motor was faulty and needed to be replaced. I also got it checked at Correa car cool, an AC specialist who came up with the same answer.

I wanted to know if this is something that other car owners also have encountered and if there is any way to repair the motor without replacing it. The cost of replacing the motor is about 25k approximately. The service centre also said that since this part is not prone to failure they don't keep it in stock and would have to order it.

25K for an AC blower? That sounds too steep!
You should get the quote double checked from other sources.

On a side note, it is possible to buy a complete 1 TON Split AC for the 25K, for the same money as this blower.

I wish I could install that 1 TON ac in my car! The ac blower unit is not available anywhere in the aftersales market. I have no option but to go to a skoda dealer :(

OK, my situation is not exactly the same as yours, but take a dekko at my thread here:

http://www.team-bhp.com/forum/techni...fter-hour.html

VW did start out by saying that the compressor was shot and later changed that to "the blower motor is shot" etc. and that they would replace them under extended warranty etc. But I was convinced it was neither of those and that they needed to look deeper into the issue.

It took VW quite a bit of back-and-forth to identify the cause and possible solution, but now they're saying that the evaporator sensor is borked and that they are replacing it.

I am supposed to get the car back this evening (hopefully).

I am wondering if that might be a possible cause for your issue too?

Cheers

Thanks guys for the feedback!

So here's an update on my issue with the blower motor. I finally got the blower motor replaced. It took about 10 days for the new motor to arrive. The cost of the motor was about 12k approximately. The total bill however was around 17k with the plenary cowl cleaning, labour and washing charges included.

The new motor initially seemed fine. But now there seems to be another problem. After about 15 minutes of running the motor at maximum speed, the speed suddenly reduces to half. This is observed in manual as well as auto mode. When this happens, the motor remains at medium speed (three LED lights glowing on the rotary dial). This can be manually reduced using the dial but cannot be increased beyond this point. When the dial is increased, all LED bulbs light up but speed remains constant. If the car engine is switched off and keys are removed, then the motor resumes high speed again for another 15-20 minutes as before. I have observed this issue only while running the blower at maximum speed. At lower speeds it seems to work fine.

From all the posts on the forum relating to similar issues, it seems the culprit maybe the resistor or evaporator. Let me know if there is anything else I should consider. The car is scheduled for a check up in a couple of days. On the phone the service adviser said there could be a problem with the AC control panel. If so, then it would have to be replaced. To be honest this 'to be replaced' bit gives me the jitters. A lot of stuff on my vehicle has been replaced already. So Skoda, you need to really look at your quality control

My Vento TDI 2011 AC stopped working couple of days back all off sudden. When I switch on the ac there is no air being blown in any of the AC vents. I tried in auto as well as manual mode no success.

Vehicle has done 92K and 7the service is also due. I have booked a service appointment with Volkswagen Rajajinager, Bangalore tomorrow.

What could be the issue with AC? Any suggestion, inputs will help me tomorrow when I deal with service advisor tomorrow.

Way back I had a blown fuse for the blower motor in my Swift. A year back, there was a loose connection at blower wiring inside the dash in my wife's Alto.

Hope nothing serious with the AC it-self.
Hope for the best.

I too hope (pray ) nothing serious with the AC it-self. I hope it is to do with fuse of Blower motor or some lose connection. Fingers crossed. Thank you for your response.

Hello TBHPians,
I've encountered a peculiar problem with the AC on my Fiat Punto 90 HP multiple times.

Scenario 1:
When the temperature in the ACC is maintained at low (say 16 degrees), the cooling literally stops for a few minutes (it stopped for 20+ minutes on one occasion). Opened the bonnet to check for the blower condition, it was OFF. Even though on the ACC display, the blower sign was ON.

The system recovered after a few minutes (did not switch off/restart). The blower was actually ON and the AC started working again. After noticing this issue 5 + times now, looks like the blower cuts off when the temperature is set to the lowest for a extended period of time. Visiter a FNG and since the AC was working fine when I reached there, they did not understand what I was trying to say and gave me vague reasons like the blower cuts off once it reaches a set temperature. Which I think is false as the AC becomes completely unresponsive for a few minutes.

Scenario 2:
Car was parked outside on a sunny day (40+ degrees for 5 hours) during a trip. Came back and switched on the car to find that AC had stopped working. Drive back home for 30+ kms without AC.

Worked fine the next day.

Any pointers, suggestions so that I can get this fixed?

My Swift 2005's AC stopped working today after last being repaired more than 10 years ago.

The AC button lights up, but the compressor turning on/off cannot be heard and there is no cooling. I took it to the ASS today and the relays checked out okay and they need time to diagnose. I am planning to take it to a known AC shop tomorrow to get it checked.
The car is anyway due for its annual service and if the compressor is faulty, will get it replaced then.

The SA at MASS said it can happen due to a leak and low gas too. Any pointers before I get ripped off would be appreciated.

First thing to check is supply to the compressor clutch. - disconnect the wiring coupler and see if the voltage supply to the coupler is ok.

Sometimes it is a simple issue of the wiring at the coupler being cut.

Then check if the clutch operates in direct power from, say the battery.

Then check if the refrigerant pressure in the system is fine - at very low pressure, the compressor won't turn on.

A problem noticed today with my Chevy Beat's blower. When set to defrost (towards windshield), it blows air as per the fan speed setting. But when set to other than defrost, there is no air coming in to the cabin, only the usual noise is there. The compressor works fine, so does the fan speed setting.

Any inputs? Thanks in advance.
