Where is fuse or relay for windshield washer pump? on 2004 Cadillac Seville SLS

I just bought this Seville SLS. Fine car, no doubt. Washer fluid pump doesn't pump. Could intake port be clogged, or is it a relay/pump issue?

If no sound from the pump when activated, check for power to the pump which is mounted on the bottom of the tank. If power and ground are present replace pump. Or have this done. IF pump runs check for blocked hoses.
