The power windows on your vehicle are controlled by an electronic control module , as are the power mirrors !
Power Window System Components
The power window system consists of the following components:
• Driver door module (DDM)
• Passenger door module (PDM)
• Body control module (BCM)
• LR power window switch
• RR power window switch
• Window up and window down relays in each of the rear passenger window switches
• Window lockout switch
• Reversible power window motors in each of the doors (circuit breaker protected)
• LT DOOR CB 25A (System power for left rear window)
• RT DOOR CB 25A (System power for right rear window)

Your best bet , take your vehicle to a qualified repair shop.

if you look in the owners manual it will have a listing of the fuses and the location of the fuse box. 6-64

"The fuse block access door
is on the driver's side edge
of the instrument panel.
Pull off the cover to access
the fuse block."

Fuse #10 in the rear fuse panel

I assume you are talking about the controller on the driver's door. The Driver's Door Module is likely defective. For troubleshooting purposes, you can swap in the passenger side module to verify.

Common problem.

If you have automatic climate controls, replace the blower control module mounted on the blower itself under the glovebox.

If you have manual climate controls, replace the blower motor resistor assembly, same location.

Remove the plastic skid guard under the glovebox to access the bottom of the blower motor. Remove the 2 tiny screws that attach the part. Then open and empty your glove box. Stick your finger in the access hole on the left side of the door, press the spring and the door will flip upside down. There you will have access to the wiring connectors for either part. Remove this, and the part should drop down. Very easy procedure.

both the rear passenger side wont unlock ???? How many doors are on the passenger side ? Or both back doors don't unlock ? Two relays lock / unlock the back door's Not the lift gate . The BCM controls the relay's . The relay's are located in the rear fuse box . Under back seat .

it could be a fuse.

check and see if your rear control is working for the radio, if not: that could be your problem. All of the power for the rear of the envoy is controlled by this module.
