How to test the fan on a Saab 900?
Use Fuse Taps (from RadioShack etc.) or similar flat contacts in the relay socket to avoid damage to the socket. To measure the fan current, put a meter set to a 20-amp range in series with the test leads, across contacts 30 and 87. It is safer to test the fan curent with engine off:
Why is the low speed fan not working on my Saab?
If the fan never comes on after the engine is shut off, the low speed circuit may not be working. If the fan resistor burns out, or if the low fan speed circuit fails for other reasons, the fan will continue to cycle on the high setting to cool the engine, but the coolant (and engine) temperature will run about 10-15 degrees C high.
When does the radiator fan run on low or high?
Regardless of whether the fan is cycling on low or high, the gauge will stay at 9 o’clock. The cooling fan runs on Low when the coolant temperature is over 100C, and High when over 113C.

When did Saab start using a turbocharger?
Saab introduced a turbocharger in 1978 in its 99 Turbo with the B engine (based on the Triumph Slant-4 engine). This engine was also used in early 900 Turbo models.

When was the first generation of the Saab 900 made?
Unsourced material may be challenged and removed. The Saab 900 is a mid-sized automobile which was produced by Saab from 1978 until 1998 in two generations. The first generation from 1978 to 1994 is known as the “classic” and the generation from 1994 to 1998 is known as the “new generation”.
