Fuse block '96 DeVille

My father in laws '96 Deviles AC quit working. He bypassed the low pressure switch, but the pump never kicked on. I looked at the wiring diagram in a Haynes manual and it showed two fuses and two relays and a fusable link in an underhood fuse block. But we cant find it. The Haynes manual shows it on the firewall just above the blower motor. Unfortunately the picture is of a Fleetwood. There is no plastic cover in that area on his car. Help! The old man is frying in this heat. Thanks.
