Question about 2006 GMC Envoy
Check the washer pump. It is located under the air cleaner assembly. There will be a connector with tow terminals. there should be power on the red wire anytime the washer button is pressed. There should be ground on the black wire at all times. If there is no power than check the washer fluid fuse and relay in the underhood fuse block. If there is power than the pump is probably bad.

if your wipers work it is not a fuse,
if you cannot hear the pump humming when you push the wash button you will need to replace it,they are around $20.00 at Autozone

Rear washer may have it's own reservoir . Can you hear a pump humming when you activate the washer? Look in the under flooor compartment

do you hear the mini washing water pump noise (working)? if no: check fuse panel where labled washer... if yes: there could be a blockage in the very fine sprays ontop of hood, due to prevoius not clean water used before or any pricipitant..... you need to use a very thin wire or tool to clean it

the same reservoir is used for both ...it uses separate pump motors.....if the wipers are working the fuse for the washer pump is good...check the power and ground for the pump...
