The pump just stopped working all of a sudden so I'm suspecting it may be the fuse.
What fuse services the windshield washer pump? no separate listing in owner man. on 2002 Buick Park Avenue
Red wire at washer pump should have power at pump when switch is pressed, black is ground. Instrument panel fuse box fuses marked WSW/RFA 10 amp and 30 amp fuse WSW are for wipers and washer circuit.
