I have a 2003 Buick Rendevous CXL with all power including Head’s Up Display. The Head’s Up went out along with the air circulation controls (fan speeds and digital temperature display). I have checked the fuse box in the console and the fuse box in the engine compartment. all fuses appear to be good. What do I need to look for now?

thanks for your help…

Most likely there’s a problem with the Body Control Module.

The BCM is the gateway for the LAN (Local Area Network) where computers/modules communicate with each other.

Kind of makes one miss switches, wires, and mechanical controls. I mean gateway, lan, to describe car problems is a little scary. Sure I am a computer guy but always remember the if microsoft built cars, modified for your enjoyment.

Every time they repainted the lines on the road you would have to buy a new car.
Occasionally your car would die on the freeway for no reason, and you would just accept this, restart and drive on.
Occasionally, executing a maneuver would cause your car to stop and fail and you would have to re-install the engine.  For some strange reason, you would accept this too.
You could only have one person in the car at a time, unless you bought "Car95" or "CarNT".  But, then you would have to buy more seats.
Macintosh would make a car that was powered by the sun, was reliable, five times as fast, twice as easy to drive - but would only run on 5 percent of the roads.
The Macintosh car owners would get expensive Microsoft upgrades to their cars, which would make their cars run much slower.
The oil, gas and alternator warning lights would be replaced by a single "general car default" warning light.
The airbag system would say "are you sure?" before going off.
You would have to hit the start button to turn off the car.
You would like to take off in the morning but have to wait for updates to install, then restart.
You would need to buy third party protection to prevent hijacking of your car. 
Your car might last 10 years before the operating system is obsolete and no longer supported.
Whenever a new version comes out you can forget everything you know and start learning all over.
There will be people trying to make you switch to ubantu for your car.
Google will offer google wind shield and drive your car for you, and even offer net car so you can do everything you need to do with a 99% uptime guarantee, so there are only 87.6 hours of the year you have to probably worry about your car not working.
