2012 Expedition rear wiper issue
 

Hey all,

As of late when I turn the rear wiper on, it move intermittently at best stopping. the rear window is free and clear of obstacles.

I am wondering if this is a motor issue? if so, how easy or hard is it to replace?

Suggestion, before possibly replacing a good wiper motor, a thorough check of the wiring to the motor might save you some trouble. Especially, where the wiring flexes every time the rear door is opened.
