Replacing the Window Motor
Estimated time: 2 hours at best, 4-6 hours realistic

0) Use duct tape to secure the window to the top of the door frame (I used three pieces)

1) Remove the door panel
a) Remove the panel around the door handle (small panel) by pulling backwards slightly, then popping out. The door lock comes off by pulling out on it (with force). Then lift the panel up and around the door handle.
b) Remove the three screws (one on the far left, one on the bottom, and one behind the panel you just removed.
c) Pull out the power window/lock mechanism (if equipped) by pulling slightly down and out, then detach the wires.
d) Remove the small panel opposite the side view mirror. This is accomplished by pulling back slightly, then pulling out.
e) Pop the door panel off it's hinges.
f) Remove the bracket behind where the handle was.

2) Remove the weather proof plastic wrap.
a) Just start at the top and pull down carefully removing the wrap from the door, being careful not to rip/tear it.

2.5) Remove the wire connection from the top of the motor (found at the top right of the door frame).

3) Remove the four rivets attached to the motor and regulator.
a) There are many ways to remove rivets, I punched out the middle with a drill bit the size of the inside hole on the rivet, then used a dremel to cut the rivet in half, and used a hammer/screwdriver to bust off the outside and punch the rivet through.

4) Remove the regulator/motor
a) Attaching the bottom slide bar (sash channel) of the regulator are two bolts, remove them (I removed the left first, then right).
b) The top bar of the regulator is attached by two nuts/bolts attached to two small brackets. You must reach inside the door panel and loosen the bolts so that they slide off the brackets. [Be careful to keep one hand on the motor as the regulator/motor will come tumbling down at this point!]
c) You need to jockey the units around but they should all slide out the hole in one piece (regulator/motor)

    5) Replace the old motor with the new one.
    a) Drill a hole through the back plate of the regulator and sector gear. Stick a pin or bolt through the hole to hold the spring-loaded gear in place.
    b) Remove the three rivets attaching the motor and regulator (as described before)
    c) Replace the old motor with the new one (making sure to align the gears) and bolt the motor/regulator together.

    6) Now place them back into the whole and do everything in reverse, attaching all the pieces.

1999 oldsmobil silhoutte sound like it boils when idling and cooling fluid looks a rusty color

Both--but you have to find out what problems
the motor has & make those repairs first,don't
use it if it overheated, even once,park it & work on it

Rusty in color-that's neglect & no preventative maintenance,
unless you just bought it, in which case you lay it up for a couple
weeks & go thru it

Filter or valve problem in the transmission. Transmissions also need regular fluid changes and filter changes and most people do not know this. You can do this yourself, or have someone do it.

Where is the starter on the 1999 oldsmobile silhoutte

Under the front of the engine, where it meets the transmission...and under the motor mount. If you disconnect the negative cable from the battery and jack it up, it's relatively easy to gain access. If it's still in original condition, remove the 10 millimeter bolt that's holding the plastic cover. Then remove the bolts that go straight up. Wiggle the starter out and down and then disconnect the two wires. I hope I've helped. If so please rate my assistance and leave a comment to help others in a similar situation find their answer. Thanks for using Fixya.
