You should see power at the plug.  Any chance you disconnected the intermittent amp?  That's what controls the power.  I think it's in that area where you were doing all of your relay work.

i do have power at the wiper plug... just the blue red i think... the one that has the power going there all the time..  my question is should i see power at any other wires at the plug ? or are all the others grounds?

i can also check if i undid the intermittent relay by passenger foot area....

and can i bench test the motor by putting power and ground to it?

They get power depending on where the switch is, I think.  There's slow, and fast, and park.

Find the pin on the motor that matches the B wire and that would be your ground.  Ground that pin and apply power to the other pins and something might happen.  I'd work through the diagram and description and pick a pin but that would be work and it's Saturday.

So that’s how I would bench test the motor ? Ground it amd apply power to all other wires? Why 6 wires??

Here is the FSM for the Body Electrical of a 74 260. And the picture that tells most of the story.

LR is power the motor, B is the ground and you ground either L or LW to get low or high.  LY has something to do with the park function.

Took motor to a Bench with battery.  Hooked ground up abs tried pos.  One worked with a clicking.  That was after I put motor back together.  Does that mean motor is done??
