Power comes from the battery, through the blower fuse, through the blower relay, through the blower resistor module, and then to the blower itself. Test all of those points and determine which of them the power isn't getting past.

Try this: Pull the 10A "HEATER" fuse out of the driver's side panel. Then try the blower. If the blower works with the fuse out, I can help you solve that particular pain in the EVER LOVING *** problem that I had to chase down this summer.
If you've had a leak on the passenger side, odds are the problem isn't too complex. But try pulling that fuse just to rule out the worst scenario.
Here's an EWD.

Bypassing ECU to get blower motor working.
After a total of at least 14 hours over several days we fixed the problem we had.
All components work except ECU lead to Relay box so we bypassed it.
We didn’t have the heater fuse problem as some have had so we were quite stumped.
Following the lead of people who suggest cutting and grounding the purple wire coming from the ECU wasn’t an option as why cut wires unnecessarily.
After hours of working on this we have come up with a different solution.
We opened the relay, cut off and dremeled down the terminal that plugs into the ECU lead in the relay box.
We soldered a wire to that terminal inside the relay and ran the wire through a drilled hole in the relay cover to a ground under the dash and problem solved.
No cutting expensive wiring harnesses.

not responsible if you car blows up 😁

I have just been contacted by somebody about this situation and unfortunately it’s being almost 3 years so I apologize if don’t really recall everything.
On the Aristo the relay is behind the left-hand kick panel.
It was the left tab of the relay we cut off, it was plugged into the purple wire that went to the ECU. We cut the tab off the relay (making sure that there was no way it was going to make contact once plugged back in again) soldered a wire onto it, ran it through a new hole in the relay and then there’s a steel tube up under the dash we drilled a hole in and connected the wire with an eye a self tapping screw.
