Power Window No Power at Fuse#1

Power Windows Woes

I am hoping that some kind soul will help me understand where the power comes from for fuse #1 in the luggage compartment.
When my Power windows dont work, which is intermittent, there is no power at this fuse posistion at all, even when touching the wire directly.

At the #1 Fuse there are 2 wires. The upper is black and the lower is Red/Blue stripe

Can anyone tell me if the this fuse #1 is fed voltage via the ignition switch or the Power Window Control Relay 944-615-116-00

PLEASE AND THANK YOU

The schematic shows that power comes in the top of the fuse through the black wire from the Passenger Window Control Unit. The red/blue wire runs from the bottom of the fuse to pin 1 of the connector in the frunk to connection 5 of the passenger window switch on driver's side door.

The PWCU gets it's power from the red/black wire at pin 7 which originates on the top side of fuse 5 in the left hand fuse block in the schematic above (the X bus - powered with ignition switch in ON and RUN positions) and pin 2 a large red wire from the top of fuse 2 (the 30 bus - always hot bus).

Fuse panel connections.



^^^^^
You will need to print/cut & tape these two pages.

^^^^^
Note, the small three fuse block is located in the engine
compartment behind a plastic cover.
And is not associated with your issue.

Fuse #1 and #5 are your fuses of interest.

Best,

Gerry
