Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
all the other windows work fine it is just the passenger side window will not work at all ?
do you have a mutli meter on hand ?
with the passenger switch connected turn it over and back probe the terminals in the connector and with the key ON does the dark green show 12 volts ?
does the solid black show a good ground ?
the dark green does NOT show 12 volts with the truck on or the ignition key ON ?
if you are sure the problem is that dark green wire gets its power from the window circuit breaker the SAME place the drivers window gets its power from since the drivers side works fine the issue with these is usually that dark green wire broken in the door jam pass through rubber area or very close where that wire passes through into the trucks dash area
finding and fixing that dark green wire so it has 12 volts with the truck on should fix this problem
but the dark green wire is supposed to have 12 volts at it with the truck ON
ok back probe the BIG brown wire with one meter lead and then the big dark blue with the other meter lead set to DC volts when you push up on the passenger switch will it read 12 volts and when you push down also 12 volts
one 12 should be + and other 12 should be -
the window motor works off reverse polarity to go up and then changes polarity to do down
