Noisy internal ventilation/heater motor/fan

[blease]

Hi all,
I've done a thread search and looked at 996 technical articles but I cannot find anything about a noisy internal ventilation motor/fan. Its getting quite intrusive now, even at low fan speed settings. Is checking/changing this simple or involved? Would apprecoate some guidance.
Many thanks, Simon

It might be debris in the fan blades, which I have heard of happening on more than one occasion. Take out the pollen filter and take a look in the opening. You might find something stuck in the fan. Other than that, if you want the instructions on how to remove the fan, drop me a PM with your email address a,d I'll extract them from the workshop manual.

Actually, I'm so sorry. I did a google search and found out its very simple on Pelican Parts. Its mainly a question of getting the correct part. There is a difference between 1998 and 1999 MYs. I have 1998.

Cheers Andy. EU spares currently out of stock. Will try clearing the pollen filter and pulling the fan out for inspection. It looks very straightforward....then will give Douglas Valley a go.
Cheers chaps!

It is worth checking for debris before you you replace it. Try adjusting the HVAC settings to see if increasing fan speed influences the noise.
It's quite straight forward to remove, but you need to remove the glove box to get access to it. You can find some steps here:

I had a similar issue a few years ago & found some insulation material had peeled away from the flap above the HVAC motor & below the pollen filter. Removing the debris fixed the issue.

My fan went noisy and then quit a couple of years ago , I got a replacement from Euro Car parts , it was the same make as the original , the only difference was the connection for the loom ( different plug) this came from the OPC , I brought 2 just in case , delivered for just under a £10.00 , easy fit , you just have to get up personal with the passenger footwell ! My car is a 99my.

Mine went noisy last year until it stopped completely.
The fan housing can be dropped passenger side - only two screws hold it in place. You may need to take a third out to pull lower dash for space and all has to be done on your back.
I expect you can get the fan working just by using WD40 on the bearing. Mine is working fine now. Note the fan is similar to VW/Seat/Skoda part.
