The windshield washer pump in a 1999 Oldsmobile Intrigue gets its power from a
fuse and is controlled by a
switch (usually located on the steering column). The fuse protects the pump circuit. The switch completes the circuit, allowing power to flow to the pump when you activate the wipers/washers.
You'll need to consult your owner's manual to find the specific fuse number for the windshield washer pump. The manual will also likely have a diagram showing the fuse box location.
