Wipers work just fine when you turn them on, just nothing when I push the button. Can't seem to locate a fuse for this. Can anyone help with the location of the fuse. Swapped the relay with no luck.

The wipers don't sweep when you push the wash button? Do the washers function as designed?
The wash switch operates the washer and wiper through the Genral Electronics Module (GEM). Access to that module isn't for the timid or rookie tech. Located behind the center of the instrument panel, testing won't be easy.
Key on, engine off, accessory or run, when you press the wash switch, you should have battery power on the light blue with orange (LB/O) wire going into Pin 13 of the GEM.
The GEM then switches the wash relay to ground on the tan with red (T/R) wire coming from Pin 24, allowing pump operation.
Without all of this, you won't have normal washers.
