You have to drill down and follow the embedded links on the diagrams.

On this diagram..

click on any blue "A1" and it'll take you to this page..

Selecting the link for the General Module Wiring diagram LHD 2005/09+ takes you to...

This shows the four fuses feeding the A1 module. You can click on each fuse number to view it's location and use, which takes you to this...

I can't see any common voltage source or ground that would cause all the pump motors to fail at the same time. The only common item is module A1 and obviously any device that either controls power to the A1 module (like relays) or causes the A1 module to do something (like a stalk switch telling the A1 module to turn on a pump motor).

To track this fault down you may need to start looking at inputs and outputs from the A1 module, to eliminate both the module and any control systems.

The A1 module is here: -

To loop back to the beginning, you stated the fuse under the glove box was god. Which fuse did you check? F14 or F41? Or both?
