Where is the power window relay located in a 2002 mercury villager?


Principles of Operation
The driver power window regulator motor is controlled directly by the master window/door lock/unlock switch (and its integrated "auto down" module). Power is supplied to the power window relay and the master window/door lock/unlock switch, and the passenger power window switch when the SEC/timer module grounds the coil side of the power window relay. The SEC/timer module will ground this relay when the ignition is in the ON position and will remain energized for approximately 15 minutes or until the driver or passenger door is opened.
The driver power window regulator motor is a reversible motor that is operated by applying power and ground to the motor leads to lower the window, and then reversing polarity on those leads to raise the window.
The passenger power window regulator motor is controlled directly by the passenger power window switch and can also be controlled by the master window/door lock/unlock switch. Power is supplied to the power window relay and the master window/door lock/unlock switch, and the passenger power window switch when the SEC/timer module grounds the coil side of the power window relay. The SEC/timer module will ground this relay when the ignition is in the ON position and will remain energized for approximately 15 minutes or until the driver or passenger door is opened.
The passenger power window regulator motor is a reversible motor, which is operated by applying power and ground to the motor leads to lower the window, and then reversing polarity on those leads to raise the window.
The power rear quarter glass is also directly controlled by the master window/door lock/unlock switch. The power rear quarter glass power latches also utilize reversible motors. The power rear quarter glass power latches are operated by applying power and ground to the motor leads to open the window, and then reversing polarity on those same leads to close the window.

Which Relay/Fuse controls the power windows?


Did you check for battery voltage at the switch , with a volt meter before you replaced the main driver door switch ? Maybe you'll want to take this to pro ,instead of just replacing parts !

1995 chevy z71 k1500 350. breaks wont work


"have put all new breaks, lines, sensors." For the Mechanic to get the brake fluid in the line to the calibers. It has to be pump by stepping on the brakes pedal. You said "no breaks" so that did not happen.

My question is does the master cylinder work? A lot of work was done that was not needed to be done.
The Dealer will not do any thing if they did not work on the brakes. If the Dealer did this job then you can complain about them.

The black box you are referring to is call ABS control module. It should be on under the hood on the driver side of the radiator. These units do fail.
You can go the the Auto store and ask, if they carry it then they will know where it is locate. You can also go to Dealer parts department, they will carry the part and can show you where it is locate.
If you do replace the control module, make sure the brake line is properly bleed of all air.
I do hope this help you

Check inside wiring by the driver's side door hinge. Remove the rubber boot and you will find broken wires. Make a splice and you are fixed!

Wont start security light stays on


My girlfriend had the same problem, so we took it to the local dealer in Costa Mesa, CA and were told she needed a new engine to the tune of 5K. We decided to take it to our local mechanic and he discovered that the “ignition control box”, which apparently has the antitheft controls too and shuts the flow of gas to the engine because it thinks its being stolen when it malfunctions, was causing the starting problem. Once, the box was replaced it worked fine. Because the IBC controls antitheft, it will need to be “reprogrammed” be someone that has access to the proper equipment or the dealer. I think the whole thing was about $800 - $900. Sure beats $5,000

Hope this helps,
B

Driver window will not work


The black boxes inside the fuse box are indeed relays, which will make a clicking noise. The window buttons are merely contact switches, and if they quit operating properly, the window simply won't do anything, but I've never heard any noises come from one when it quit working. The relays can easily be replaced by hand, so go to a local auto parts store to see about purchasing one, and ask them to show you on their computer screen exactly which relay in your fuse panel is the one that controls the window circuits, and replace it yourself. It's very simple.
