The window regulators are about $130.00 each, and can be changed in about an hour if you are mechanical.
I wrote a full post with pics, but the pics were deleted. The regulators are made of cheap plastic with cables. It is designed to fail.
Whatever you do, do not try to lower your windows if there is a chance of them being frozen or stuck. The cable will jump off the spool and ruin the whole regulator.
And Ford wonders what they are in the shape they are in. I just sold my Expy after 7 months on the market.
Here is the post detailing how to change the regulator, but no pics.
