Power options only work occasionally

Need to check for power at the relay...wiper hi-low relay... connection at the relay (85) 12v and (86) GEM module you should have voltage there also make sure the key ON ACC when check-in it. same for wiper run relay (85), (86), (87) should all have power with key on and turn wipers on...need to check which side is not getting power.

Do the wipers work ? Fuse for wipers is same as washer pump .
Principles of Operation
The wiper motors receive inputs from the following:

• Multi-function switch
• Powertrain control module (PCM)
• Ignition switch
• Smart junction box (SJB)

The following components are integrated in the wiper motors:

• Windshield wiper motor module
• High/low speed relay
• Run/park relay
• Washer pump relay
• Park sense (Hall-effect sensor)

Washer System
The windshield washer and the rear window washer are activated by the internal wiper motor modules when it receives a ground from the multi-function switch between the washer inputs. Depending on the correct ground, the internal wiper motor modules activate either the windshield washer or rear window washer relays (internal) by grounding the respective relay coil. When either module is activated, it connects voltage to the washer pump while the deactivated module provides ground to the washer pump. In this manner, voltage polarity is reversible to achieve directional change of the washer pump and washer fluid.

Does your expedition have programmable/recall memory option for seats an mirrors ?
Driver Seat Module
The power driver seat and power exterior mirrors are controlled by the driver seat module (DSM) only when the vehicle is equipped with the programmable/recall memory option.
On the Expedition Limited, the power fold exterior mirror option is controlled by the DSM. Before running a self-test or retrieving codes, the power fold switch must be inactive for at least 30 seconds.
This is a complex vehicle , electronics , control modules an serial data communication networks. You mite be better off taking it to the dealer or some other repair shop . There could be DTC'S - diagnostic trouble codes stored in the SJB - body control module !

Normal Operation During normal operation, when the front wiper wash is selected, the windshield wiper motor provides power to the washer pump through circuit CRW14 (BU/WH) and ground is provided to the washer pump through circuit CRW12 (GY/OG) and the rear wiper motor. If rear wiper wash is selected, the rear wiper motor provides power to the washer pump through circuit CRW12 (GY/OG) and ground is provided to the washer pump through circuit CRW14 (BU/WH) and the windshield wiper motor.

Possible Causes
• Multi-function switch
• Open in circuit CRW14 (BU/WH), CRW12 (GY/OG), CRW07 (GY/BN), CRW20 (GY/YE), SBB49 (RD) or GD149 (BK/GY)
• Short to ground in circuit CRW14 (BU/WH), CRW12 (GY/OG), CRW07 (GY/BN) or CRW20 (GY/YE)
• Washer pump
• Windshield wiper motor
• Rear wiper motor

Could be the switch at the bottom of the barrel has came loose

As far as the window goes, it sounds like your switch is going bad. If you continue to use as it is, the switch will keep getting worse and worse until eventually it doesn't work at all. So you will need to take the inner door panel off and replace the switch. Then the windshield wipers, sounds like a similar problem. However, this time, only part of the electronics are not working properly, but unfortunately you will have to change the whole thing also. The wiper switch is a little more complicated, so if you are not fully familiar with it, you would be better off to take it to someone who is.

one thing to check is the connections on the back of the audio device. and then check the connections on the back of the speakers

on your signal switch,wipers there all attached together,one goes you need to change the whole thing

Try to run a ground test on the motor, If it gets power, then you neeed to replace the switch.. if it doesnt run with the ground test, then you need a wiper motor.

it could be either.  However it sounds like you need a new switch.
