Beats me - I'd just leave the relay out! Could be a bad power seat control unit (located in the seat frame itself, under the cushion, as seen
here).

Please use a lower case "b" when referring to Stu's "bible". It has numerous errors, and cannot be taken as gospel - as you discovered. All non-V8 cars have a fuse in position D for the aux fan. Only 94-95 M119 V8 cars have cube relays with integrated GM-style fuses instead, located separate from the main fuse box. So yes, your car does need a good fuse in "D" position for the aux fan to operate.

Um, yes. Yes, you do.

If you read my previous post, you would know how to test it without running AC and without getting the car hot: "....
you can easily test this by shorting out the pigtails at the red or green switch at the AC drier behind the left headlight." This will turn the fan on low speed. If it doesn't run, check for +12v at the preresistor below the ABS pump. If voltage is present at only one side, the resistor is bad. If voltage is present at both sides, the fan itself is bad.
