How do ypu replace wiper washer pump on a 06 armada?

There are two relay's in the under hood fuse / relay box . Wiper relay an wiper relay 2 . Maybe one is bad . also check fuse #14 25 amp. Wiper fuse.Plus the BCM - body control module has a hand in making the wipers work . Are you familiar with automotive electronic control modules ?
The Wiper/Washer System consists of the following components:
• Windshield wiper/washer switch
• Body control module (BCM)
• Wiper micro 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
• WIP/WASH 10A fuse
• WIPER 25A fuse

Wiper/Washer System Description
The body control module (BCM) controls wiper motor low speed operation. The washer pump and high speed operation are controlled directly by the wiper/washer switch. The windshield wiper/washer switch supplies voltage on the signal circuits to the BCM for windshield wiper/washer operation. When WASH, MIST, DELAY, LOW, or HIGH is detected, the BCM energizes the wiper micro relay by suppling voltage to the relay coil. This allows battery voltage from the WIPER fuse to flow through the relay switched input then through the contacts and out the relay switched output to the wiper 2 relay switch contacts. Since the wiper 2 relay switch contacts are normally closed to the low speed circuit of the windshield wiper motor, the motor will operate at low speed.

Do you have any speed !

If the washer fluid is not pumping and they're new, something isn't connected right. They're obviously not getting power. Either that or the pumps didn't work in the first place.

wipers and washer should be on the same fuse
could be the switch

Have someone press or hold the washer switch and listen underhood for a small pump sound {Hum}. If you don't hear a small hum you probably need a new washer fluid pump, pretty common for this old of a car. Imagine for the last 15 years sitting in wet fluid,sometimes drying out, getting refilled, turned on and off, on and off that little pump had it's day and retired! Most auto parts stores sell inexpensive replacements. Easily come out and go back in in reverse order. Pumps are usually mounted underside of fluid tank,just follow any visible washer hose.

Hyundai started using plastic washers to hold down wiper arms. This is to prevent damage to the wiper transmission in cases where the wipers are either frozen to the windshield or trying to push too much snow/ice. To remove the wiper arm, you will need to locate the washer and remove it first. Chances are the washer will be the only part you need to replace.

The most common problem I find in this season, is having summer 32 deg. F freezing windshield wiper fluid in the tank rather than -20 deg. F freezing windshield wiper fluid.

Try to warm up the car by parking it in a heated garage until the windshield wiper fluid thaws. Then, try to use it all up, and add the 'winter' vs. the 'summer' formula of windshield wiper fluid.

If this does not solve the problem, the pump might be burnt out, in my experience.

You should hear a humming sound as you depress the button for windshield wiper fluid inside of the car.

Good luck on this repair.

remove the hose from the wiper arm and see if when you push the washer button that the fluid comes out the hose,if it does the sprayer nozzel is plugged if not replace the pupm

the little pump inside the washer fluid reservoir is bad, replace it

Remove the windshield wipers. Pull away from windshield until and use a screwdriver to pry clip on bottom of wiper arm and remove entire arm from mount. Now remove shroud that is under wiper arms you just replaced. After you move the shroud, you should be able to get at the pump.
