Does this mean that I will not get an answer.
Expert:  Gary replied 12 months ago.

it is a meter to test for power and ground

a test light on hand ?

we have to see at the RR window switch is when the vehicle is running if the blue wire shows 12 volts at it at the switch

with a new switch and motor we have to see if we are missing power or ground

these are also common for broken wires in the RR door opening pass threw in the door jam

can you look for any broken wires in the door jam ?

Customer: replied 12 months ago.
My husband did test the wires and they are working. The Juice is working. And do not see wires jammed or broken.

does the blue wire at the RR switch show 12 volts with the truck ON ?

is the purple AND light green wires at the RR switch BOTH good grounds ?

Sorry he said he tested with a test light and the light came on with the car turned on.
Expert:  Gary replied 12 months ago.

if the blue shoes 12 volts and with a new switch and motor in the RR door and it still does not work up or down then this comes down to a bad drivers master switch assembly OR the purple or the light green wires are bad between the drivers window switch and the RR window switch

the blue should be 12 volts then when you push the switch up or down from the drivers master switch the purple should show a ground when pushing up or down and then the light green should show a good ground when pushing up or down

the odds are the issue is the drivers master switch bad not sending the grounds back through those 2 wires
