Contacts in window motors sometimes get dirty from lack of use. Take a rubber hammer and beat under the interior edge of the open door while working the switch (don't be gentle). It it works, exercise the window more frequently.

Need to get a wiring diagram. Buy a book and follow the wiring schematic. It should help you out majorly. Can't really work on electrical issues without one.

My doors will not lock by using the button and my windows wont roll down or up, everyone says its a fuse, cant find the problem or the fuse???


Window fuse's and relay's may be up under driver or passenger side dash or behind glove box, under the hood and even under the seats, and finally on the ends of the dash.
Drivers door window switch gets used the most so it could be the motor, window switch, relay or fuse.
Could also be a broken wire in the rubber boot going from the door to the body. Actually, there may be a circuit breaker type relay for each window and one fuse for all the circuit breakers.

If all has failed, remove drivers door panel, or the switch may "pop out" of the arm rest. Check for voltage coming to the main window switch connector. If no voltage, problem lies somewhere between door and power source. If voltage is present, but no voltage(when pressing switch) at drivers door window motor means its the switch, especially if its a auto down or up switch.
You may also find that the connector has simply come loose from the master window control. Good luck!!

Where is the power window relay located on the '03 Buick Century? And could this be the problem for all windows to stop working at the same time EXCEPT the driver's window? Or possibly the lock switch not...


The lock switch is designed to keep the passenger buttons from being used. It should not stop the master switch from operating the windows - or at least, that's what the 2003 Buick Century Owner's Manual says.

After studying the schematics for your vehicle, Iwould say that the owner's manual is correct. The lockout switch only cuts power to the passenger switches. The driver's (master) switch can still power the passenger windows. If none of the passenger windows work from either the driver's door switch or the passenger switches, then the master switch probably has an internal open circuit causing this. There is no separate relay or fuse. I would replace the master switch. Be sure and check ALL switches with the lock on and the lock off to verify this before replacing anything.

THE REAR WINDOWS ON MY 1999 BUICK REGAL WON'T ROLL DOWN. DO YOU THINK IT'S THE MOTOR FOR THE WINDOW AND IF SO DO YOU KNOW WHERE I COULD GET THEM FIXED?


If its both windows and the problem started with both sides at the same time, then the problem is not with the motors. I would check the owners manual to see if there is a specific relay or fuse that controls the rear windows. also.....and I don't mean to insult anyone's intelligence here, check to make sure the "child safty lock" on the drivers side door panel is not engaged. I've seen that happen before as well.

Windows wont roll up and down and hazard continues to click even when not on.


These are two separate issues.The most common cause of the clicking is the hazard switch located above the radio.Replacing this generally takes care of that issue occassionally it is a malfunction in the turn signal switch but most likely the hazard switch. If all windows are affected would check fuses first.If the windows roll down from the corresponding switches example rf allows rf to roll down. If not suspect an electrical issue such as fuse or relay.If they do roll down from the switches on the doors but not the drivers door possible a master switch issue.Drivers door contains a master switch that controls all windows.Do the windows work at all?

Windows wont let down only driver side lets down


The cause of the problem is the master switch in the drives door. There is a weakness in the "lock" switch mechanism such that when it fails all power to the other windows is cut off. Either replace the switch or jumper the outer end cables on the switch connector plug.

Pass.side power window won't work.


First be sure the window lock in the drivers side master switch is not LOCKED. This will prevent the windows from being rolled down by any other switch. (p106+)

Usually windows operate off a RELAY - not a fuse... and all the windows work off the same power relay.

Your Relay Part Number is 41-5021.
Here is the electrical schematic for your windows - showing the relay is common to all windows.

CLICK HERE for a better pic.

If the relay is replaced - and/or tested good, You will need to remove the offending door's panel and verify the motor is getting 12VDC when you press the button for it to go down.

If there is 12VDC when you push the button, the motor is bad.

If there is NOT 12VDC when you push the button - the master switch or child lock bypass switch is faulty.

Click HERE for a PDF version of your owners manual

Under the ROADSIDE EMERGENCIES section (p.245) you will find a layout diagram of your fusebox.

P.248 instructs to pull DOWN on the fusepanel door to access... however your power window relay is located under the driver's side dash.



If the other windows work - there are 3 options to test/replace - in this order
1. Relay
2. Master Switch
3. Window motor.
