Where is the fuse or relay for the winshild wipers in a 91 legacy wagon?

The fuse for the front windshield wipers should be located under the dash on the drivers side, in the fuse panel just in front of the door. Looking at my 1991 Subaru factory manual, I don't see a relay that is specific to the front windshield wipers. The back windshield wiper has a relay that is on top of the right rear wheel well, just behind the right rear speaker. Here's some help with diagnosing your windshield wiper issues... If the windshield wipers do not operate... A) in all positions: 1) Blown M/B or F/B fuse 2) Wiper switch 3) Wiper Motor 4) Wiper Link 5) Improper grounding 6) Open wiring harness or poor terminal connections B) in INT position: 1) Wiper switch 2) Intermitent unit (built into wiper switch) 3) Open wiring harness or poor terminal connections C) in Low or High positions: 1) Wiper switch 2) Open wiring harness or poor terminal connections D) in Mist mode: 1) Wiper Switch 2) Open wiring harness or poor terminal connections
