Electric window problem
My son has an '03 Explorer. The passenger side window will not go down. We took the panel off the door and used a volt meter to check to see if voltage was coming from the switch to the motor. Both the up and down side of the motor pigtail was getting fire from both the driver side switch and the passenger side switch. We bought a used window assembly (cables, motor, etc) and tried the switches. The switch worked until the window was fully extended to the up/closed position, then would not go down...just like the one in the door. Took the motor off the window assembly (the original one still in the door) and tried the switch and it works fine...both up and down. There seems to be a limit switch or something that knows when something has over extended (sorta like my brain). Anyone have an answer?....for the window problem...not my brain problem.

With the door open and when the window is up all the way and the motor won't lower it, try helping it by palming it inside and out and trying to pull it down. If the "jump start" works, the problem is likely that the track is either misaligned or just grimy. If it's cold where you live, old dirty grease that is now cold can cause the window to bind. There is a resettable circuit breaker in the window motor assembly that opens when the window reaches the end of travel in either direction and stalls the motor to prevent a motor or wiring from burning up. The same could be occurring if the window "sticks" when up all the way.
Speaking of "sticks", do you know if this window was ever maybe taped in the up position due to a broken regulator? Maybe some of the tape adhesive is still on the window or in the window seal.

Thanks, Rod, for the ideas. It is definitely cold. 30 for a high for the last two weeks and below zero at night. Didn't want to try forcing / assisting the window down because of the cold. Would be in a world of hurt if it wouldn't go back up. Will check for dirty / cold grease first. The circuit breaker seems more of what we are experiencing, however. How can you reset the breaker? The window has never been taped up to work on the regulator.

Well, I'm not suggesting you hold on to the window with all your strength and hang from it, but more of a help to see if that help gets it started. But I understand the hesitation, it would make for a cold drive anywhere if the window got stuck.
The circuit breaker internal to the window motor assembly resets by itself, and quite quickly. If the breaker and load on the window is what's causing the window to not lower, you likely would feel that on the window as well when holding it to help. You would get at least a little bump feeling as the motor tried to move the window, stalled, and the breaker opened.
The factory wiring diagram shows the item as being a circuit breaker, but as fast as it resets once the current is removed, I'm not so sure it's just a breaker.... Fortunately I have not had a reason to take one apart. However, since you swapped your motor with a used one and they both function the same, I don't think it is a situation where there's an issue with the motor or breaker.
