Today I got in my car an put the heaters on

There is a sound coming on all speeds

Mostly is a high pitch squeek an maybe a grinding sound

I'm asumming it's my fan for my heaters so if anyone can guide to a how to get it out an check it would be appreciated

Hello mate,

How long is it since you changed your pollen filter? I've heard of trapped leaves causing the symptoms you describe as they get caught up in the fan.

It might be worth your while removing the filter (two minute job) and giving it a good clean out as well as feeling behind the facia for any loose leaves.

Make sure you put a sheet down in the front passenger footwell to collect all the rubbish that is likely to fall from the pollen filter before you remove it!

Hope this helps & good luck.

I did actually clean the filter about 3 months ago however I will try this again in the morning hopefully should do the trick

Chances are the A/C gas is low. If you have auto A/C, try switching it to ECON, and see if the noise stops.

Have hardly used the ac, and not auto just on and off

Got the actual fan out was nice and clean took the pollen filter out that was also fine put it back together and sound has gone for now let's just hope it doesn't come back

Hopefully sorted then.

My mk1 had a similar symptom. Until the fan stopped working at all. In the south of France. In summer. In a heat wave.

I was so desparate I even went to the local VW place. They said new motor, but next week.

In the end I stripped out the fan motor and had a good look. The commutator was starting to short out with the carbon from the brushes jamming between the segments.

I happened to have a jnr hacksaw blade which was the perfect fit between the segments. A few minutes scraping, on reassembly showed it worked perfectly. And continued to do so until the car went.

Just in case.

Sadly the sound did come back but is coming and going so might be getting a new motor soon

Tried cleaning the commutator, as above?

Cheap, not hard.

Now sound is not going and I think the bearings or something in the fan have gone hopefully sort on weekend

When I did the above, a drop of oil from the dipstick had to do - it was certainly sufficient. Smooth as silk, quiet as a mouse and any other cliché you can think of for a pleasing outcome.

I'll try that in the morning but where exactly did you put the drop of oil

What's the commutator???

Oil first: a TINY drop in the brass bush/bearing round the spindle.

The commutator is the copper segments which the carbon brushes run to provide the conductive path to power the thing. Search for one on google images, I found one but the url was massive.

There will be a couple of wires going inside the motor. At some point they will be connected to two black rectangular blocks of carbon, these are the BRUSHES. They rub on the commutator, making the electrical circuit and at the same time allowing the armature (the whole rotating thing) to rotate.

The commutator is not solid metal, just bits glued on. A fine junior blade is about the right thickness to just carefully scrape out any crud build up. Only go just below the surface of the copper.

A wipe with a cotton bud soaked in switch cleaner or alcohol will help. I used vodka.

Note- you may have to undo the thru bolts to remove the end cap, be careful not to snag anything, only dismantle as far as necessary. Don't break any tiny wires.

The trick with the brushes, which are spring loaded, is to ease the brushes back out far enough and use the little springs to press on the side to hold them in place to make it easy to fit over the comm and get everything back together. Flick the springs back once assembled.

This is assuming yours is the same as the one on mine.

I did all this with virtually no kit on a sweltering French campsite one afternoon after a particularly "heavy" lunch. Should be peanuts.

I'll give it a try on the weekend and update you guys
