Make sure the stat fitted (and the one you replace it with) is the correct temp range, and a genuine Saab 3 stage one, 1)closed, 2) open with heater 3) open without heater. Also before replacing the rad fan or thermo switch, disconnect the switch, and touch the terminals together with a piece of wire, and see if the fan runs, then change try cleaning the terminals on the switch, reckon ect the wires, and run the car upto temp make sure it switches out.
