My 1987 325i. The electric windows stopped working and will not roll up at all. No motor sounds, nothing. Is there a relay or something that i need to check. Fuses are good. Please advise

Electric or manual? If you hear the motor (electric) running or you can feel the mechanism working (manual) when you try to roll it down then the window is most likely stuck to the weather stripping and has come out of the track inside the door. If it is electric and you hear nothing then start with the fuse.
The relay operates all the windows. The drivers door switch is the master and has to be connected for the rest to work. It sounds like you have a bad motor or a bad connection on the motor in the drivers door.
I don't know how old the car is, but my windows are always the first things to go.
If the window sounds like its trying to roll up but is getting jammed (while it is rolling up try gently pulling up on the window when it gets to the point where it stops) then it might have jumped off the track.
If pulling up on the window gently while rolling it up allows it to continue and roll the rest of the way then you have a bad window motor.
Both are fairly easy to replace and you can probably buy a replacement that bolts into place from your local parts store. Let me know if you need any more help.
I would suspect the window switch on the door. Sounds like the down switch part off the switch may not be working. Before replacing the switch I would get some spray that is made to clean electrical contacts. Should have it at any auto parts store or even radio shack. Spray the electrical contacts on the switch and clean it up real good and see how it does.
hi, take the door panel off and check the window motor. sounds like the resistance of the window going back up is causing the motor to slow down and freeze up. higher than normal amperage is required to roll the window up, rather than down which had gravity helping it. unless there is a bad spot in the regulator(the part that controls the window going up and down). windows will freeze up when the internal brushes get worn, sitcky. check the motor by tapping on it with light force while rolling up when it gets to the sticking point. or help the motor by pushing pressure up on the window through the range. if it works okay like this, it's the window motor. but when you go to buy a part, you may find that the window motor maybe included only as assembly with regulator. check it out.
I replace glass in cars for a living and I see this often. I also own an 02 ES300 which had the same problem. It's usually from lack of use that a rear doorglass stops working. The electric motor gets some corrosion in it and stops working. I repeatedly slapped the interior door panel while activating the switch that rolls the glass up or down. After about 5-10 minutes of this it started to work. If you get lucky like I did, make sure you roll the window up and down multiple times if you get it to work. Then remember to occasionally roll all the other windows up and down a few times every week or so to keep this from happening again. Good luck!
If all other windows work, it sounds like the switch is falty or the motor is bad that rolls the window up and down. Or the connecter that goes to the power window switch in the door that won't roll up the window is coming unattached from the switch.
actually you have thought of all but the prob. The track has jumped, making the motor not move the window. Sometimes you can gently slide the window up by hand and then the motor will catch the track and finish rolling the window up
Window motors & regulators go bad every day. Pull your door panel, unplug the motor, if you have an ohm meter apply the leads to the leads into the motor. One will be ground the other two will raise and lower (reverse) the motor. If you show resistance between the leads the motor windings are good and the problem may be the window regulator. If you do not have an ohm meter, you can run two wires (one ground, the other hot) and test the motor by applying elec to it.
