Subject: 95 9K CSE ACC temp drift ?


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. My theory is that the indoor sensor gets heated inintentionally by something. First guess of a source was the Radio/CD, which is mounted close to the sensor inlet - but that didn't seem to be it after all (switched radio off for an hour after problem appears - still too cold). Oddly enough - adjusting the temp setpoint a degree or two upwards gives a few minutes of warmer air, but then we're back to the chilly stuff... Problem exists both in summer (25 centigrade) and winter (+1 centigrade) outdoor temps. Problem exists both in auto and economy settings (winter - didn't try economy in summer). Anybody experienced this ? Anyone know a fix (auxillary CPU fan behind the sensor, maybe ?) I'd hate to have to slow down just because of this :) regards Per Laursen (1995 9000 CSE 170hp - really nice car!)
