Subject: Overheating '86 900S - very strange....

I've had cars overheat before and one thing you can always depend on to cool them down like right now is a pleasant drive down the highway at 85. But this time all it did was cause the temp to keep *rising* almost into the red(!), and only by heading for the exit and getting into 25 mph traffic was I able to bring the temp down. The exact opposite of every overheating situation I've ever encountered, but Saabs are a bit unusual, so this isn't all that surprising <g>. Really comes down if I park it and leave it idling with the A/C on full blast. Maybe because both fans kick on and run constantly(?). Has not gone all the way into the red so far, so there's been no actual boiling over, and the gauge seems to be working consistently, so I don't suspect it. If it means anything, I know my heater control valve is bad because I'm always getting some heat out of the side vents with the control turned off. I was meaning to get to it, but got sidetracked replacing the blower motor in my Volvo 240 (and that requires a recuperation period before diving into any more fun projects). Anybody have any ideas?
