Windshield Wipers Quit 04 LowMax

Honestly Bill probably not worth the aggravation to fix it. Save yourself the frustration lol.

Great find. My stock wiper arms on my 2000 use to have different angles, think the arms I replaced my stocks with when I repainted the truck were both the same angle.

 

How To Build a Western Star:

Step 1: Take the wiper motor and Pivots
Step 2: Assemble all other parts around it

82.00 Windshield Wipers and Washer
Wiper Motor Replacement
100/2 Western Star Workshop Manual, Supplement 11, November 2008
Replacement
1. Apply the parking brakes and chock the tires.
2. Disconnect the batteries at the negative cables.
WARNING
Disconnect the batteries before working on the
wiper motor or linkage. Otherwise, if the driveshaft
is forced out of the parked position, the
motor could cycle, possibly resulting in personal
injury.
3. From underneath the dash, remove the HVAC
wye duct, located under the center of the dash. A
bracket attaches it to the dash, with a bolt, nut,
and two washers; see Fig. 1.
4. Disconnect the motor wiring from the electrical
harness.
5. Reach behind the mounting plate and remove
the nut, item 3 in Fig. 2, that attaches the drive
crank to the wiper motor drive shaft. It may be
helpful to hold the linkage in place with large
locking pliers. Remove the drive crank and the
linkage from the drive shaft. Use care not to
bend the linkage when pulling the drive crank
loose from the drive shaft.
6. Remove the four nuts and lockwashers, items 7
and 8 in Fig. 2, that hold the mounting plate to
the brackets. Remove the wiper motor and
mounting plate.
7. Remove the three Torx screws that secure the
wiper motor to the mounting plate. Note the orientation
of the motor to the plate for installation.
8. Attach the new wiper motor to the mounting
plate, using the three Torx screws. Tighten the
screws 54 lbf·in (610 N·cm).
9. Place the linkage on the wiper motor drive shaft,
then start the nut on the shaft, but do not tighten
it yet.
10. Position the mounting plate on the brackets, then
install the four lockwashers and nuts. Tighten the
nuts 13 to 17 lbf·ft (18 to 23 N·m).
11. Make sure that the wiper arms are in proper
parking position, then tighten the nut on the drive
shaft 15 to 18 lbf·ft (20 to 25 N·m).
12. Connect the wiper motor wiring to the electrical
harness.
13. Install the HVAC wye duct under the dash. Attach
the duct bracket to the fascia bracket on the
dash with the bolt, nut, and two washers; see
Fig. 1.
14. Connect the batteries.
15. Remove the chocks.

 

NOTE: The wiper linkage is located inside the
cab. Some disassembly of the dash components
and/or HVAC ducting is required for access.
Driver-Side Wiper Pivot
Replacement
1. Apply the parking brakes and chock the tires.
2. Disconnect the batteries at the negative cables.
WARNING
Disconnect the batteries before working on the
wiper motor or linkage. Otherwise, if the driveshaft
is forced out of the parked position, the
motor could cycle, possibly resulting in personal
injury.
3. Remove the driver-side wiper arm; see Subject
110.
4. Remove the cap and the retaining nut from the
driver-side pivot drive shaft; see Fig. 1.
5. Tilt the steering wheel down, or, if the vehicle
has a non-tilting steering wheel, lower the steering
column as follows.
5.1 Remove the wiring clamp from the side of
the steering column, to access the steering
column capscrews.
5.2 While supporting the steering column, remove
the four 3/8-inch capscrews and
washers that attach the steering column to
the steering column bracket. Carefully
lower the steering column.
6. Remove the four Phillips screws that secure the
main dash panel, then swing the panel open; see
Fig. 2.
7. Remove the three capscrews that secure the
ECU mounting plate; see Fig. 3. Rock the
mounting plate out of the way to gain access to
the driver-side pivot.
8. Pop the linkage from the mounting knobs on the
pivot. The drive link connects to the mounting
knob on the forward side of the pivot, and the
drag link connects on the aft side; see Fig. 4.
Use care not to bend the linkage.
9. Remove the pivot. Note the position of the inner
retaining nut on the pivot shaft.
10. Position the inner retaining nut on the new pivot,
at the position noted on the old pivot.
11. Position the new pivot in place.
12. Press the linkage onto mounting knobs on the
pivot. The drive link attaches to the forward side
of the pivot, and the drag link to the aft side.
13. Position the ECU mounting plate in place, and
secure it with the three capscrews; see Fig. 3.
14. Close the main dash panel, and secure it with
the four Phillips screws; see Fig. 2.
15. If the steering column was lowered, raise and
install it as follows.
15.1 Lift the steering column into place, and
install the four 3/8-inch capscrews and
washers that attach the steering column to
the steering column bracket. Tighten the
nuts 23 to 29 lbf·ft (31 to 39 N·m).
15.2 Install the wiring clamp on the side of the
steering column.
16. Outside the cab, install the retaining nut on the
driver-side pivot drive shaft. Tighten the nut 12 to
15 lbf·ft (16 to 20 N·m), then install the cap on
the drive shaft; see Fig. 1.
17. Install the driver-side wiper arm; see Subject
110.
18. Connect the batteries, and test the wiper system
operation.
19. Remove the chocks.
Passenger-Side Wiper Pivot
Replacement
1. Apply the parking brakes and chock the tires.
2. Disconnect the batteries at the negative cables.
WARNING
Disconnect the batteries before working on the
wiper motor or linkage. Otherwise, if the driveshaft
is forced out of the parked position, the
motor could cycle, possibly resulting in personal
injury.
3. Remove the passenger-side wiper arm; see Subject
110.
4. Remove the cap and the retaining nut from the
passenger-side pivot drive shaft; see Fig. 1.
5. From underneath the dash, remove the HVAC
wye duct, located under the center of the dash. A
bracket attaches it to the fascia bracket, with a
bolt, nut, and two washers; see Fig. 5.
6. Pop the drag link from the mounting knob on the
passenger-side pivot; see Fig. 4. To reach the
passenger-side pivot, lie on the floor under the
dash with your feet out the passenger-side door,
and look up behind the HVAC ducting.
7. Remove the pivot. Note the position of the inner
retaining nut on the pivot shaft.
8. Position the inner retaining nut on the new pivot,
at the position noted on the old pivot.
9. Position the new pivot in place, with the pivot
shaft through the hole in the cab.
10. Snap the drag link onto the mounting knob on
the pivot.
11. Install the HVAC wye duct under the dash. Attach
the duct bracket to the fascia bracket with
the bolt, nut, and two washers; see Fig. 5.
Wiper Pivot Replacement
12. Outside the cab, install the retaining nut on the
passenger-side pivot drive shaft. Tighten the nut
