Climatronic fault & noise from behind glove box

[Huweth]

I think there are 2 fans. I only know of the one behind the glovebox, although they both might be there...

Perhaps you could try removing the glovebox and playing with the climatronic. This way you might be able to hear/feel the sounds better, and know if it is that fan or the other one (wherever it is).
I've heard that that particular fan is not too difficult to change, but it could of course be other parts next to it, which I haven't heard of people having problems with, so have no idea if it's easy or not.
Good luck!

Hi everyone

I've been doing a bit more investigating and the noise from behind my glove box is the motor that drives the flap to source air from either inside or outside the car.

It starts when the engine is started and the motor is drive the flap open. The noise stops as the car increase speed - I guess to reduce the amount of air flow into the car. I've also press the button on the climatronic control to source air from inside the car and the noise stops!

You can put the climatronic into diagnostic mode and select option 13 which shows a reading from 0 to 255 (255 - outside air/0-internal). This can be adjusted and when the value drops below 255 the clicking noise stops. You can also see the flap moving when adjusting this value. When you start to drive the car the value decreases as you speed up.

I've been to VW and they think that is the fault too because they have a lot of those motors in stock.

Havent replaced it yet as not had time to find out how to get to the motor.

Hope this helps and will keep you all posted.

how do you put climatronic into digonostic mode?

Hi, I have exactly the same symptoms on the same car Sr eg Passat. This started about 12 months ago and I have been without air con / heater since. It was a gradual process over a month or so but then finally nothing happened. I also get the flashing display on the control unit for the first 10-15 secs. I changed the climate control unit earlier this year but this didn't solve it. It's getting near to winter and I was hoping that I could find the cause without having to go to VW dealer. your findings would be greatly appreciated.

Hi, Have heard of lots of issues with recirculation motors clicking, typical symptoms are clicking noise from behind glove box area. To replace motors believe that the dash has to be removed to gain access.
If the climate control panel flashes it usually means there is are fault stored in air con. control unit, a diagnostic test will give you a trouble code which from there you can find root of problem.
Hope this helps, Golfer7

Any joy Darren?

I took my car to Martins in Farnham (used to be Barnet and Small), they have quoted me £650 + VAT to carry out the job. Saying it's mostly labour and that the recirculation valve isn't expensive...

So, looks like I'll be doing this myself sometime soon!!!!

Hi,

It wasnt the motor driving the air flow flap, it was the brushes on the fan. I took the fan out and the brushes were very worn so I clean them up put the fan back in and the problem has gone away!!!

I had the exact same problem with my 2000 Passat Tdi. Removed the glovebox, removed the heater motor and brushes were well worn. Fitted a set of these and its now as good as new. The dealers charge about £250+vat for the morot then labour on top!!!!
