Wiper/Washer System Components
The Wiper / Washer System consists of the following components:
• Windshield wiper / washer switch
• Windshield wiper system module / motor
• Windshield washer fluid pump
• Windshield washer fluid level switch
• WPR 25A fuse
Wiper / Washer System Operation
The windshield wiper motor module is part of the windshield wiper motor cover and controls the wiper motor operation. The windshield wiper motor is a 2 speed motor. Windshield wiper DELAY operation is a low speed wiper motor function with a variable delay interval between the wipe cycles. The DELAY interval is controlled through a series of resistors within the wiper / washer switch.
Park Position Operation
When the windshield wiper / washer switch is turned to the OFF position while the wiper motor is somewhere in mid-cycle, the wiper motor module will continue to operate the wiper motor until the wipers reach the park position. If the ignition is turned off while the wipers are in mid-cycle, the wipers will stop immediately where they are. The wipers will park the next time the ignition is cycled to the ON position.

Hello: From your description of the problem it sounds like the wiper arm is bent. This could have occurred when the windshield was replaced. You might take truck back to who ever replaced windshield and DEMAND they correct the problem. The w/w arm will have to be replaced.
The wiper module is probably bad.It is located on the wiper motor many times you can wiggle the wires going to the module and some function is restored temporarily but most likely the module willneed replaced.

Windshield Wiper System
The windshield wiper system consists of :
Windshield wiper motor (17508) (F-type).
Washer system.
Windshield wiper control module.
Turn signal and windshield wiper switch (13K359).
The windshield wiper control module is:
Located at the instrument panel fuse panel.
The windshield wiper motor is:
Attached to the cowl top extension (021A36) .
Connected to windshield wiper mounting arm and pivot shaft (17566) .
The turn signal and windshield wiper switch features a:
Rotary wiper switch.
Push type washer actuator.
OFF/Low/High Speed
Has a two-speed, permanent magnet, three brush electric windshield wiper motor .
The windshield wiper motor has a brush rigging that permits selection of low or high speed.
When the turn signal and windshield wiper switch is in the LO position, the common brush and the blue/orange wire brush are used, and the windshield wiper motor operates at low speed.
When the turn signal and windshield wiper switch is in the HI position, the common brush and the white wire brush are used.
In HI position, electric current will bypass a portion of the armature winding causing the windshield wiper motor to operate faster.
When the turn signal and windshield wiper switch is moved to the OFF position, the windshield wiper motor will continue at low speed until the park switch outer contacts open.
When the park switch contacts open, the windshield wiper motor stops in the park position.
Interval
When the turn signal and windshield wiper switch is in the interval position:
The wipers make single wipes separated by pauses.
The rotary switch is on the end of turn signal and windshield wiper switch .
The length of the pause can be set from approximately 1 to 17 seconds.
Length of pause decreases as the rotary switch is rotated away from off.
Length of pause increases as the rotary switch is rotated toward off.
While in the interval wiper mode:
It is normal to hear a slight click at the beginning of each on/pause cycle.
NOTE: When using interval wipers, the first wipe may not occur until after a pause of up to 17 seconds.
My wife complained about the same thing on her BMW. After driving it on a long road trip in the rain, we realized that if you just turn it to the first setting, the wipers automatically speed up, and slow down as rain increases/decreases.
I changed the wiper motor and switch
