I am the original owner of a 2000 A4 1.8T quattro and recently I've had an interesting development. My climate control panel is now completely unresponsive. At first I could turn it on or off only occasionally and usually after pressing the "auto" button, but if I turned it off it would usually come back on after a few seconds and stay on. Now it's on all the time and there's nothing I can do about it. None of the buttons work- I can't turn the defrosters on, I can't change the temperature, I can't do squat. As it's set to 72 degrees and winters coming, I think I may be ok, but the lack of defrosters is going to kill me once it frosts. Has anyone else had this problem? I'm not sure, but I think it either happened or got worse after my battery died and I replaced it, although that may be completely unrelated.

All help is appreciated, thanks.

Sounds unrelated. I'm thinking the Climate control is unit is dying. Might want to think about picking up a used one.

 

I have found a used unit on e-bay for a '00 a4 but that unit has heated seats. I'm assuming the unit will work with my non-heated-seat climate control, is that true?

Also, is this the kind of fix I can do by myself? Is there a site/book that might go over how to replace a climate control unit?

Thanks,
Bill

 

stop using the cup holder above your radio stuff always spills out onto the radio and climite control causing the buttons not to work
