Question about 1983 Oldsmobile Delta 88
There is no relay, and there is no fuse for the power window circuit, there is a 30 amp circuit breaker in the fuse panel under the dash and the circuit breaker should be marked WDO on the fuse panel.
First check to see if there is power from the 30 amp circuit breaker to the master window switch on the driver door, and if power is getting through the master window switch.
If there is power to and through the master window switch (use a test light or a power probe would the best tool for the job), then there is most likely a broken wire inside of the weather boot that is between the door and the body of the vehicle, and the wires run in from the door through the inside of the weather boot and then through a hole on the body of the vehicle that is located behind the driver side kick panel, and the wires should be inspected from the wire connector behind the driver side kick panel out to the master window switch on the driver door for any broken wires. If you do find any broken wires be certain that they are soldered back together and do not use wire connectors to repair the wire(s) unless you want to repair the system again in about a month or two.
Here are two wiring diagrams (if the vehicle has rear vent windows then use the upper diagram) of a typical GM power window circuit for that year to help assist you, and let me know if you require any further assistance.

It sounds like a power supply problem. I can't see all 4 motors broken.
First how does the switch "feel" No buttons loose?
Does it illuminate when you switch sidelights on?
If that's ok
I would gain access to the master switch on the drivers door.
I would think you have to remove the door panel and armrest I can't remember for sure, but it doesn't take a lot .
Check and make sure all the multiplugs are connected first of all.
Make sure all the terminals in the plugs are fully "home"
If there is nothing obvious i would follow the loom to where it exits the door and goes back into the car and check for damage.
Check for ANY other electrical equipment not working, if so go back to your handbook and re-check which fuse it goes through.
Also, if this problem has occurred after a recent repair, I suggest you return to the repairer.

Since all fuses are okay, I would start my trace from the fuse box and pick the easiest wire to trace which would probably be the lighter or aux. Check for any breaks in the line or any lose connections. It seems like a harness may be disconnected or cut.

#1 that vehicle has atleast 2 seperate fuse boxes, 1 located under the hood, and the other either under the dash board (driverside) or on the side of the dash board also on the driverside (cant remember which1 for sure, i own the same year explorer but its getting a trans. overhaul at this time, sorry.) anyway, make sure to check both of those areas 1st. i know there is a fuse for all the window motors, but there are relays as well, check those too. I seriously doubt it would be a bad drivers door master switch cluster, but you never know. all in all i would re-check your (owners) manual once more to locate the window fuse(s) and relay(s). If I remember correctly they do have fuse and relay charts in there for sure, just exactly where in that manual I cant remember, but its in an odd spot of the manual from what I recall! I know its not much help, but it should get you started in the right direction. Good luck and let me know if you have any more ?'s.

There is a posibility that the connections may have been block or the connection to them is broken ... this also happens while servecing car the water get is the main system but happens real rear ... so you can go to work shop and ask electrition for check ..

If you checked the fuses and they are fine, try this. With the key on and the window button down or up, open and close the door holding in the up or down position. If the window moves, there is a wire(s) are broken in the wire harness that goes from the door jam to the door. This is a common problem that we find with window and door operating problems. You may find 1 bad or broken wire, or 4-5 broken wires. Let us know if this help you find a repair, for this concern. Craig
