Where are the fan fuses on a Saab 900?

The two fan fuses (30A and 40A) are in the same location. The fan can be tested with the engine on or off (but preferrably off), by removing first the “Fan Low” relay, and putting a test lead, or a heavy wire jumper between relay socket contacts #30 and 87.

How do you test the fan on a Saab?

If the fan never comes on after the engine is shut off, the low speed circuit may not be working.
