∙ 2011-09-13 17:54:48The motor is going to need replacing. I found a replacement on eBay and did it myself. You have to raise the gate and take off the rear panel to access it. I had to use my old bracket because the replacement models' was different but the motor mounted to my old bracket just fine. Just search Ford Expedition rear wiper motor on eBay. I got mine for about $50 new.

There are several things that can cause your 2003 or Expedition to misfire. The most common cause is a plugged catalytic converter.
Check linkage first and stripped or loose wiper arm on spindle.
In relation to the washer fluid, check if the fluid tube is not twisted or blocked in anyway.
The delay system may not have anything to do with the switch. It depends on the manufacturer but the delay system maybe part of the wiper motor assembly...or the delay is sometimes located in a separate module located separately from the control switch.
One possibility is your wiper motor is bad. Suggestion- replace it.
If the rear window is not fully closed the rear wiper will not operate.
Stripped spindle/splines, linkage issues.
It may be due to a broken linkage.
a blown fuse.
Replace the wiper circuit board. It went bad on both of our blazers. It isn't too expensive. Pretty easy to get to too.
I have a 2000 olds alero and the signal light only work sometimes, What would cause that?
