If you have ECC, the '93 940 diagram shows a "dual relay" (my term for item 2/10) called a "Power unit ECC", which appears to control item 6/28, the "Cabin fan motor".

The pictorial shows 2/10 to be near the fan motor.

It has 2 harness plugs and appears to be fastened in place by 4 flange bolts, 2 on each side.

Fan ground side comes in on a blue/black wire at terminal 1A,
and connects to grounds via white/black wire from terminal 2A,
when a coil is grounded via blue/red wire from terminal 3 to Control module pin 22.
