heater problems

I have a 2004 A4 avant and the heater wont blow on the screen. It works we on other settings but when flicked over it seems to soound like its blocked. It stopped working a few weeks ago and then worked again but now has stopped in other words its intermitant. I have been told it might be the servo. Is this accessable without removing the dash?
any help much appriciated.

Windscreen Blower

I have an A4Avante and I can`t get the heater/aircon to blow up onto the windscreen. It used to work fine, and works still in all other positions, but when I select up or front screen, it doesn`t work, this is causing a misting problem.
I have removed the dashboard vent, to see if there is a blockage, but there doesn`t appear to be one.
Does any one have any advice, thank you Dave.

Hi Dave,
I have now sorted the problem. It was the actuator (electric motor sticking) if you remove the glove box 5 8mm bolts you will be able to see the 3 actuators on your right. the one in the middle back is the the sticky one. if you change the heater direction on buttons you will see this one doesn't move. I belive they are around £60 to replace but give it a wack and it might start moveing again. Ass this is a worm screw dont try and force it as you wont move it. Its prob getting stuck.

Good luck

Graham

Graham, i removed the glove box today, and lubricated the actuators and gave them a tap. They are now moving as they should, so thanks for your help, Dave.
