I had the same problem but now it seems a lot better: Have you taken the temp sensor out of the dashboard and blown out all the dust that collects in there? To get to it, you have to remove the radio or ACC unit, it pulls out from behind. If you're handy with a soldering iron, you may want to replace the temp sensor. It looks like a diode in a small glass package, but it is actually a NTC thermister, specs are 10Kohm <per.laursennopsamSPAMil.dk> wrote in message news:3dea6d86$0$71652$edfadb0fnopsamd11.news.tele.dk... > I have experienced several times that after running at highway speeds > (140km/h - about 90 mph) for an hour or so, the ACC tends to let too cold > air into tha cabin - it gets rather chilly.
