Power windows won't work

I just got an 86 325 and I have no manual, just wondering why the power windows won't work, is it a fuse or what? I was told there is a button on the dash that resets the circuits but that button is missing, any help would be appreciated.
Thanks

check fuses first and if good check for power at the switch

You may have to remove your door panels to access the motor units. Check for power to the motor; in none, check the individual switches. If there's power to the motor units, try 1. replacing it with a salvage yard motor. 2. Remove it and see if it is merely 'stuck' with dried out grease.

I had the same problem and finally fixed it this moring on an 80 528i and whaddya know? The window works!
Have fun...

Replace the circuit breaker, if the button is missing... It's only about $35.00.....

I am new here, and I really don't use forums much, so I hope this is the right place to post. Sorry if it's not, but I'm hoping I can get an answer. This is the closest to one of my problems that I've seen as I searched, so anyway... I have a 1980 528i and the front passenger window doesn't really roll down. If it does, then it gets stuck in the down position, so I have to keep it rolled up. Sometimes this happens to one or both of the rear windows as well. Also, the sun roof will no longer roll open; it only tilts up, and then it gets stuck in the open position. Is this old wiring needing to be replaced? How would one remove door panels to check? Is it something I should leave to a mechanic, if neither my husband nor myself know much about car repair? (The car was bought new by my grandmother, and now, years later, it's mine.) It has other problems, too, like the door lock mechanisms and the gas flap latch mechanism not working. I can't lock my car, and I have to open my trunk to manually pull back the gas flap latch whenever I need to fill up the tank. Also, the left turn indicator activates the brights when the headlights are turned on. I am trying to decide whether I need to have all these things fixed or try to get a new car. Any advice would be great. (Sorry this is long.)

All those problems could be a combination of problems but most likely as you mentioned electrical, it could be the switches (had the same problem with a window switch that wouldn't roll up the window all the way), the locking problem i think because of a lock control module (small computer box) it can be located in several places (driver door/under glovecompartment) I say check with a dealer for that specific vehicle.
But in overall i think you need a electrician more than a mechanic :S

I would take it to a dealer and let them look at it. There would be about an hour diagnostic time but at least you would know what you're dealing with. My first thought was the bmw window regulator. This would also make me think it is an electrical problem, or a combination of both....

Don't play with the button, switch may be affected. Take it to the dealer first.

Goodluck!
