How to know if it's the switch or not.

2003 mercury grand marquis.
Driver's window doesn't work.
I thought I could swap door switches to check it out but that wasn't possible since they were neatly packaged in a rectangler box.
So what/how do I check to know if it's the switch or the motor?
Thanks

Hello and good day:

Do you Have a Volt-Mulitmeter??

In most cases the motor to the power window unit is your cause.

Good Luck and good repairing Sterling_6

Re: How to know if it's the switch or not.

If you press the switch and the dome lights dim, the brushes in the motor are hangingup. If so, hit the bottom of the door with a rubber mallet while holding the switch and the window will probably start working. If it does, you'll know that eventually, the motor has to be replaced. If it doesn't dim, do as Sterling_Six mentioned and check for power.

It's fixed, for now!

You guys were right-on again.
It was funny, my GF knew it before I did. I was being careful where I was hitting on the bottom of the door. I held the switch down and took the rubber mallet and hit it a couple of times and she says "it's down!" After being stuck for so long I didn't expect it to work so smooth and quiet. When the motor finally goes I'll be back. I know what I'm getting my GF for Xmas, a service manual!
Thanks again,
Rock

Hi, Bert. This is exactly how I tested them at the Lincoln Mercury dealer in the early seventies.
