Changed temp sensor and no heat a few days later

[jlstewart3]

I have recently changed my temp sensor. About 4 days later my heat stopped working. There was not any leaks on the floorboard. I do notice that aluminum pipe in the kick panel was not warming up. I didnt want to think it is the heater core. It seems very sudden. Any other things to look for? The heater core is the only part of the cooling system that is not new so far.

I would start with an ACC calibration test and see if any fault codes show up: http://saabworld.net/showthread.php?t=28199

Also check to make sure your coolant is at the correct level.
