1971 A body Power Windows

[Canuck]

I installed all the power windows in my 71 442 about 6 months ago. All new wiring, relays and switches.
About a month ago they stopped working.
I was able to disconnect the harness from the relay under the left kick panels and run a jumper wire from the main feed to get them working.
Here is the result;
Both front windows function properly.
The left rear window goes up when I press it to go down.
The right rear window won’t work at all.
I have a new relay on the way but won’t have it until next week.
Is the way I have jumped the power and bypassed the relay causing it to function like this.
