Hello everybody.! I desperately need your help and advice. I own an Octavia 1.6 diesel mk35e dsg 2013 model. Today for the first time and after 260000 KMS I heard a noise and felt a slight vibration and as a result my ac gave 20% of the cool air . I turned it off and after a minute I turned it back onn but the same results. I turned it off and left it for 15 minutes and when I turned it on nothing. I did the same again and nothing. After a minute it started sending cool air strong as before but then the noise and vibration started again. After 2 more tries now it's working perfect . No noise no vibrations. Does anyone have any ideas ?? Has anyone had this problem??? Please help !!!

Sounds like your blower motor is failing. It's not impossible to replace but it is fiddily. You should also have your HVAC checked every 3 years....time to get a regas.

You are right on the money. I changed the blower today. As for the regas I've never done it. It's time for sure. Thank you very much for your concern help and time. 

Where should I buy a new blower from? I think I have the same issue. Thanks. 

As I understood it really doesn't matter as long as it is a known brand. All they change is the shell and the fan in it. The electrical component they take out from the old and put it onto the new one.

Ah OK, thanks. I was hoping to do it myself but sounds harder than that. I was hoping it was a case of the old one comes out and the new one goes in? 

Do it yourself. It's dead easy. It's just a couple of screws . Don't worry you LL do just fine. When you take it out you will understand what to do. It's a case of filling the blanks. It's really very easy. NIKE JUST DO IT !!!
