My 05 envoy denali has been acting weird ever since I activated the xm radio on it. The passenger door controls went out (fuse?), I see two fuses in the manual. Also the lock/unlock horn chirp went out and my bose is as loud as its ever been (speakers arent blown), but noticeable less bass now. All happened at once.

Question edited for clarity.
Question moved to model category.

Here are all your fuses

GMC Envoy (2002-2009) fuses and relays

https://fuse-box.info > gmc > gmc-envoy-2002-2009-f...

Here you will find fuse box diagrams of GMC Envoy 2002, 2003, 2004, 2005, 2006, 2007, 2008 and 2009, get information about the location of the fuse panels ...

I'd recommend starting with the fuse, if you haven't checked it already.

Your vehicle's radio uses a blue, 15amp fuse. It's possible the fuse is blown and needs to be replaced.

The fuse box will be under the dashboard, behind the cover, on the passengers side of your center console.

If the fuse is intact (not blown), the radio has either failed or there's an electrical issue that'll need to be inspected by someone who can diagnose vehicle electrical issues.

It can be issue with radio fuse or wiring issue of radio.
First test the radio fuse.If its blown out,then replace it.If the fuse i checked ok,then its radio wiring issue.Test the voltage.

If windows still work from other door switches, then fuse is good, if not check fuse, if they do replace master window switch, shorted out with the water.

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 your manuals guide book on reprogramming the radio and where would you find the fuse for the radio first check the fuse then reprogram if this information has been helpful please let us know good kuck

THERE IS USUALLY A FUSE BEHIND THE UNIT IT SELF AND CHECK YOUR FUSE BOX

IT MIGHT BE UNDER THE STEERING WHEEL CLOSER TO THE DRIVER DOOR OR UNDER THE HOOD CLOSE TO THE BATTERY OR ACROSS ON THE PASSENGER SIDE

COULD BE A FUSE. CHECK THEM AND YOU SHOULD FIND A BAD ONE. HOPE THIS HELPS. IT IS VERY RARE THAT BOTH OF THE WINDOW MOTORS ARE BAD AT THE SAME TIME. ALSO CHECK THE RELAYS FOR THE WINDOWS. GOOD LUCK. THANKS IN ADVANCE FOR AN HONEST RATING. AND FOR USING FIX-YA. PLEASE KEEP ME POSTED.
