Windows don't work

Do you have a stick? if not you have to go under start the car it is coming out is ok. not you have added very slowly until coming out. Safety first remember!!!

YOU PROBABLY HAVE THE LOCK ON LOCK POSITION. OPEN THE DOOR, PULL THE OUTSIDE HANDLE OF THE DOOR UP AND WITH SCREW DRIVER PULL THE LOCK IN THE MIDDLE OF THE DOOR TILL UNLOCK POSITION, THEN CLOSE THE DOOR.

Call a locksmith to get into it for you.

scrap it

Check the fuse for window circuit, not likely that will be an issue

The door switches get used the most,so you start there
You have to be familiar with the use of a VOM Meter (volt meter)
A wiring diagram & ability to understand that, is almost a gaurantee
to success.

Then if necessary you remove the door panels & check out the
window regulator & then the motor.

Need experience with vehicles,working on electrical & some
basic tools or a repair shop is you next stop

They don't do well or care for working inside a door,never have
for some reason. Too much time & can not charge for it!

You said windows?

If none of them work, you need a different approach
That is beyond you & requires the wiring diagrams of window
circuit & a professional scan tool to look at various
modules in the vehicle.

Don't need a dealer for any work on any vehicle ,ever,
but little you can do in your driveway for the last 20 years

It's a sealed transmission, you can't check / fill the transmission without performing a complete service.

If all four stopped working at the same time, it sounds like a fuse. The fuse should be in the cabin fuse box somewhere around the steering wheel or underneath the dash.

Check the fuse under the hood top right corner fuse box Third fuse down on the left side It is a 30 but in older Mercury Mountaineers the wires come slightly corroded and tend to not transfer enough power. So in conclusion either A: the fuse is blown or B: Boost it up to a 50 fuse which is what I had to do

If they all don't work and you checked the fuse and it's good it is the window switch. Pretty easy fix, get a door panel tool at a parts store, unscrew all of the screws for the door pull, door handle cover, and what ever else is screwed on. Use the door panel tool to pop off the cover and the switch will then be accessible.

Power windows stopped working. Have checked the fuses and they are fine. All other systems are functioning. Any thoughts?
