How do you get back window of a 1989 Ford bronco to go back up?
what you can do is remove the back panel on the tail gate, that
will give you access to the internals. now find the wiring going to
the window motor, unplug them and hook up a 12 volt source directly
to the wires and t will go up or down. when you hook it up and the
window goes down reverse the wire and it will go up.
Good luck not allot of room in there, prepare to scrape your
I would first make sure the tailgate is correctly latched. There
is a safety switch built into the driver side latch. This keeps the
window from activating (up or down) if the gate isn't fully closed.
Bypassing the switch (described above) and rolling up the window
may lead to a broken window and possible personal injury. If the
safety switch located on the drivers side latch (on the tailgate
itself) isn't functioning - it may be the problem.
Testing it is simple: With the tailgate slightly open, find the
latch mechanism in the jamb. Simulate a closed tailgate by rotating
the two half moon shaped pieces toward each other to make a closed
circle. (just as the striker does as the gate closes.) These must
be rotated and closed simultaneously. With the gate ajar, use the
tailgate key switch to try to activate the motor. If that doesnt
work, have a helper use the switch on the dash to activate
(ignition must be "on"). Listen for motor noises. If it goes up,
that indicates the tailgate is out of adjustment. The tailgate
sheetmetal (skin) surface must lineup with the corner of the rear
Dont forget to open the latch dogs by lifting the inside
tailgate handle before trying to close!!
If the motor did not activate after the test above, it has other
issues; key switch bad, safety switch bad, disconnected or broken
wires, bad motor etc.
OMG that is all great info.... also know that the key switch
will not work sometimes if the switch on the dash is defective...
most people go to the wrong switch 1st.
