Rear window Wiper Works but not hitting all of the window

Hey The rear window wiper on my Sport works but only makes contact with the glass for about the last 3rd of the sweep. Took the hatch apart to see if the motor bracket was loose or out of alignment but it all looks fine. Any Ideas or just go to the junk yard and get a new wiper arm?

A Rear Wiper That Does Not Sufficiently Clean The Backglass. To Service,
First Inspect For The Letters 'ab' Stamped On The Wiper Arm Just Below The
Wiper Blade Pivot Pin. If The Letters Are Not Stamped On The Arm, Install New
Service Arm Part # Xl2z-17526-aa. Note: Ensure That The New Service Arm
Assembly Has The Letters 'ab' Stamped On It. Original Wipers With 'ab'
Stamped Near The Pivot Pin Were Revised To Apply More Pressure To The
Backglass.

I'm having the same problem and i've tried to remedy this myself by slightly bending the rear wiper arm. I was thinking of getting a new wiper arm and seeing if that fixes this issue. Thanks for the info!

You can grind down the two wiper arm stops on the underside of the arm to fix this too. However the new arm is not too expensive and comes with the really good new motorcraft wiper blade.

Instructions:
Pivot Arm —Rear
Removal

CAUTION: Use a shop towel or similar device to protect the vehicle finish when performing the procedure.

Disconnect the rear washer hose.

Remove rear pivot arm:

Lift the pivot arm nut cover.
Remove the nut.
Remove the pivot arm. (A battery terminal puller works great for this.)

Installation

Turn the rear wiper switch on and allow the motor to operate for at least one cycle.

NOTE: This step ensures that the wiper motor is in the park position.

Turn the rear wiper switch OFF.

Position the wiper blade outside the wiper arm stop.

Install the wiper pivot arm onto the wiper motor.
Tighten retaining nut.

Connect the washer hose.

Cycle the wiper motor one time to allow the wiper arm to park on the wiper arm stop.

Buy it now for $26.99 thats a great deal!

Just called my local Ford Dealer and they sell it for 42.99 +tax

Here is what I did:
remove arm
soak in hot soapy water (with alot of working of the joint to get dirt/debris out of it)
dry
hit joint with PB Blaster
put arm back on

Here is the result:

Still could have used a bit more washing and PB Blaster, but it was freezing out, and good enough for the time being. Also, everytime I hit the carwash, I heavily spray the joint. Either that, or the slight missing is from my attempts at minor bending, of which my ex-Ford mechanic neighbor said not to do...

RockAuto sells them for $23.
