This says Pulse Board or the Switch

This says it does have a relay... but

Nothing shows where it is located.

It may not be releasing, you can test if you can find it!

..

key off, key on ,ACC or running? 4 mode KEY what?

engine running or not, if not running the accessory delay relay drops all that out. in 10min./ RTM

now read the manual for your truck, cost zero to get. from FORD. read up delay word !

must be a new truck to you no?

cars have 2 to 4 or more fuse boxes, and covered

in the glove box users guide, lost that? but yes vast fuses and relays.

I bet some things work in ACC (key position)

the delay relay drives fuse F2.401, windows. power.

when delay times out the fuse goes dead, relay opens.

this is no 1990 or older truck

this relay save damage to the battery.

5 fuses run the cluster all are KEYON only power.

one fuse is memory hot all the time does not count

one fuse is run ACC power.

one more for fun, RADIO power

if those things fail all the time ,any key position

or engine is dead say so

and scan the PCM.

or jumper cable jump start your weak battery, main.

You didn't take into account the wiper switch is a input to the BCM - body control module ,or do you know that ? The BCM controls wiper one an wiper two relay's to turn on the wipers .
Wondering if it is the PCB or perhaps a physical problem? Guessing never finds the problem . Reading how they work in factory service repair info should be the first step for someone that doesn't know .
Intermittent Operation
Windshield wiper DELAY operation is a low speed wiper motor function with a variable delay interval between the wiper motor cycles. The DELAY interval is determined by a series of 5 resistors within the wiper/washer switch. During DELAY wiper operation, the signal circuit voltage is further reduced through the DELAY resistors. The body control module (BCM) monitors the voltage on the signal circuit to determine the delay interval between the low speed wiper motor cycles.
If the wiper switch is moved from a longer delay interval to a shorter delay interval, the BCM will command an immediate wipe cycle and reset the delay timer to the shorter delay interval.
Additionally, intermittent wiper operation is vehicle speed sensitive. As vehicle speed is increased or decreased, the wiper interval will also increase or decrease.

Low Speed Operation
When the wiper switch is in the Low position, voltage is supplied through an internal resistor to the signal circuit. The body control module (BCM) monitors the windshield wiper switch signal 1 circuit and energizes the wiper 1 relay which will operate the windshield wiper motor. The wiper motor will operate at low speed, since the wiper 2 relay is de-energized. Low speed can also be commanded with a scan tool by commanding Wiper Relay Cmd. ON and OFF.
High Speed Operation
In the High position, the windshield wiper/washer switch supplies voltage to both the wiper 1 and wiper 2 relay coils. This energizes both relays and allows battery voltage from the wiper 1 relay switched output to the switched input of the wiper 2 relay through its contacts and out the switched output of the wiper 2 relay to the high speed circuit of the windshield wiper motor. The windshield wiper motor will operate at high speed. During HIGH speed wiper motor operation, the wiper switch signal circuit is at the LOW speed signal voltage, and the body control module (BCM) supplies redundant voltage to the wiper relay via the wiper diode.

Wiper/Washer System Components
The Wiper/Washer System consists of the following components:
• Windshield wiper/washer switch
• Body control module (BCM)
• Wiper 1 relay
• Wiper 2 relay
• Wiper diode
• Windshield wiper motor
• Windshield washer pump
• Windshield washer nozzles
• Windshield washer solvent container
• Windshield wiper arm and blade assemblies
• Windshield wiper transmission
• WIPER/SW 10A fuse
• WIPER 25A fuse

Left Front Power Window Switch
The battery voltage is applied from the WINDOWS circuit breaker through CKT 42 (RED) to the accessory time delay relay. The accessory time delay relay supplies voltage through CKT 70 (PNK) to the left front power window switch under the following conditions:
?€¢
The ignition is in the RUN position.

?€¢
The retained accessory power (RAP) is active.

When an UP switch on the left front power window switch is operated, the battery voltage is applied to the power window motor. The power window motor is grounded through the DOWN contacts of the left front power window switch to G204. The motor runs in order to drive the power window up. When a DOWN switch in the left front power window switch is operated, the battery voltage is applied to the power window motor in the opposite direction. The power window motor is grounded through the UP contacts in the left front power window switch to G204. The motor runs in order to drive the power window down.

there is 2 fuses that you have to check
one will be in the big fuse assembly in the engine bay, the other probably in the fuse assembly in the cab
If they prove ok then it is possible that the coolant temperature SENSOR is faulty and needs replacing
don't confuse it with the temperature sender which operates the temp gauge.

the delay and park controller under the hood on the wiper motor. the motor is cylindrical the controller is rectangular. the controller is inoperative at times. contains 2 relays within

wiper relay and time delay relay for 3-4 speed wipes.

Did you check for power at the main switch either before or after changing ?

This is the Light Blue w/ Black stripe wire on the switch connector, pin # 8. You need to have the truck in the run / accessory key position for power to get to here.

If you do not have power, 2 places to look.

1. The rubber boot that the wires run between the door and the a-pillar. This could be a broken wire in there, seen it 2 other times.

2. Problem with the accessory delay relay. You can check the socket of the relay for power on pin # 30. If need be, you can jumper the normally open contacts out, and see if this cures the problem ( bad relay )

does the motor still run if it does the arm that moves the blades have come loose if not check fuse relay or the motor itself.
