Have a 2005 envoy and just outta of the blue my whole driver side door nothing works windows lock nothing on the driver side but everything else works on the other doors need some help what could be the problem

I wonder if the Immobilizer is related to the door locks and the fuse blowing broke the pairing. Try the reset

read in your manual the section on synchronizing windows

You have to replace the whole assembly as I did with mine

the drivers door switch is also a door module and ever thing from for the door goes threw it

Try www.manualowl.com

Just figured it out and replicated it 3 times..

any type of power/voltage change seems to trigger this issue

The most common symptom is power locks fail and only the driver window quits, however that is on the extended cab.

Steps to fix and it works every time.

take door panel off driver's door
Disconnect the wiring attached to window and power lock control unit
disconnect battery cables
connect the negative to the positive cable(((NO BATTERY CONNECTED)))
This will act to short residual voltage in the system

5 minutes later
place the key in the ignition and turn to the run position
connect the wiring to the window/lock controller
connect the negative cable to the battery
then the positive
open drivers side door
turn key to the off position((do not remove yet)) you should get a series of dings through speakers telling you the key is still in the ignition
once it begins dinging pull the key out and you should hear the door lock solenoids trigger and the windows should work.

Three years and a very unhappy girlfriend who owns the truck. but she's happy now.

it could be a fuse.

Try disconnecting the battery for 10 -15 minutes. Make sure all functions are turned off first, such as HVAC (all switches CCW or off), radio off.

The switches in Subarus are made by Nissan believe it or not. They are not interchangeable. Anyway, I suspect you have a bad window switch. You can pickup the whole bank of swiches or replace just the one. Do a search on ebay for your part.
Has this car had body damage on the driver's door? You could have a cut wire inside the door.

Check inside wiring by the driver's side door hinge. Remove the rubber boot and you will find broken wires. Make a splice and you are fixed!
