Cadillac Repair: 1979 Cadillac Sevile, 1979 cadillac seville, cadillac seville

Question
I have a 1979 Cadillac Seville 5.7 gas. The power locks and the power trunk stopped working. The fuse is ok. Also the power seat on the driver side stopped at the same time.

Answer
Remove the power door lock switch from the drivers door panel and see if one of the 2 wires connected to the switch has battery voltage.

Do the same for the trunk release button. Also remove the seat switch assembly and see if you have battery voltage on the RED wire.
