2000 pontiac grand window issue
I have this 2000 pontiac grand am sedan, replaced
all four regulators and motors, all three windows
roll up and down easy, but except the left rear. The
old left rear regulator rolled down but not up,
installed a new one does the same, thought it was
the switch but isn't(swapped it with a good one
same issue). Motor does sound when going doing,
no sound when pushing up. Any help would be
great thanks.
