ELECTRICAL - REAR WIPER ARM REMOVAL -
SERVICE TIP

FORD:
2001-2004 ESCAPE

ISSUE
Some Escape vehicles may exhibit the rear wiper arm being seized to the motor and difficult to remove. This may be caused by an insufficient amount of anti-seize compound on the arm/motor shaft splines.

ACTION
For vehicle service requiring the removal of the rear wiper arm, the following Service Procedure will help to free the wiper arm from the motor shaft.

NOTE
DO NOT ATTEMPT TO REMOVE THE WIPER ARM BY CUTTING THE MOTOR SHAFT WITH A HACKSAW OR GRIND TOOL.
CUTTING THE MOTOR SHAFT WILL MAKE THE MOTOR UNUSABLE REQUIRING REPLACEMENT. IN ADDITION, DAMAGE TO
THE LIFTGATE GLASS MAY OCCUR. HOWEVER IF THE REASON FOR SERVICE IS DUE TO AN INOPERABLE REAR WIPER MOTOR AND THE WIPER ARM IS SEIZED, THEN CUTTING THE MOTOR SHAFT IS AN ACCEPTABLE MEANS OF REMOVAL. USE CAUTION AS TO NOT DAMAGE THE VEHICLE'S PAINT, GLASS, BODY PANELS, ETC. INSTALL PROTECTIVE TAPE AND/OR AN PROTECTIVE COVERING AROUND THE LIFTGATE AREA AND BELOW REAR WIPER MOTOR.

SERVICE PROCEDURE
1. Confirm that wiper arm is seized on motor and that the wiper arm retainer latch is in the "release" position.

2. Mark and LIGHTLY center punch the exact center of arm mount "circle" (area over motor shaft).

3. Carefully drill through wiper arm using 1/8" drill bit. Do not drill into the motor shaft.
NOTE
PREVENT METAL SHAVINGS FROM FALLING ONTO THE BODY OR PAINT AS DAMAGE MAY OCCUR.

4. Enlarge the drilled hole using 3/8" drill bit.

5. Apply a small amount of penetrating oil at contact area of splines for wiper arm and motor.

6. Tap on joint area lightly to create vibration and facilitate penetrating oil working into splines of arm and motor.

7. Allow the oil to sit and penetrate for several minutes.
NOTE
BE SURE THE WIPER ARM RETAINER CLIP IS IN THE "RELEASE" POSITION BEFORE CONTINUING WITH STEP 8.

8. Install a puller with a 5/16" or smaller center screw (e.g. Battery Clamp Puller) to the wiper arm so that jaws of puller are pulling against the arm, and center post of puller is pressing against center of wiper motor shaft.
NOTE
ENSURE THAT JAWS OF PULLER ARE PULLING AGAINST WIPER ARM AND NOT MOTOR SHAFT BUSHING.

9. Tighten puller in very small increments while tapping lightly on the wiper arm and center shaft of puller. With pressure applied to the wiper arm and shaft a light shock should pop arm off of motor shaft.
NOTE
BE CAREFUL THAT ARM & PULLER DO NOT FALL AND DAMAGE THE LIFTGATE AND/OR BUMPER.

10. When installing the new wiper arm, remove all corrosion/rust from motor splines and apply anti-seize compound to splines of arm and motor.
NOTE
IF AFTER PERFORMING THIS PROCEDURE THE WIPER ARM STILL CANNOT BE REMOVED, THEN CAREFULLY CUT MOTOR
SHAFT AND REPLACE MOTOR AND WIPER ARM. USE CAUTION AS TO NOT DAMAGE THE VEHICLE'S PAINT, GLASS, BODY
PANELS, ETC. INSTALL PROTECTIVE TAPE AND/OR AN PROTECTIVE COVERING AROUND THE LIFTGATE AREA AND BELOW
REAR WIPER MOTOR.
