Radio, windows, sunroof all stopped working at same time. No fuses are bad. When car is in the "on" position they all work fine. As soon as you turn to start, and the car is on and running, they stop working??? Any suggestions would help greatly!!!!
Best advices would be to check your fuses in the cabin or under the hood.
your grounding cable from battery or chassis is either loose or corroded. check your battery terminals and make sure they're clean. i had the exact same problem when relocating my battery from the front of the car to the trunk of the car. my ground cable was loose and the electrical circuit didnt seem to be going through the cycle.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

What is year--make--model of vehicle? If power windows won't work, look up wiring diagram for power windows, start by checking voltage and ground . I always check the basics, first. Fixing one system may or may not fix the others?
Sounds like you have a bad fuse, and or maybe a bad relay in your dash panels. Start by looking up the fuses that affect your sunroof, then work out to the other issues. On my Ford, there is a bad relay that affects my power windows, my radio, and my interior lights. Sometimes more than one fuse is related to a system, so check all the fuses before trying relays.
You may just
have a bad fusible link. This will often cause several of the cars
electrical systems like power windows, sunroof, radio etc. to stop
working at the same time. It is usually located at or near the battery
and built into the cable with a square plastic box that surrounds the
cable. Follow the large positive (red) battery cable from the battery
connection towards the starter relay. Look for the long separate wires
that connect to the starter solenoid or a square fuse box that surrounds
the cable. That is the fuse link and has blown due to a current surge condition, the box or insulation
around the wires will show bubbling and melting (it's supposed to do
that) or it may just have crystallized and gone bad. Basically, it is
just a wire or strip of metal connecting the two ends of the cable.
Replacement links are available at most auto parts stores. I hope this helps Tim
Well hello, very descriptive. anyway the 2000 intrigue has a BCM just left of the steering column under dash, but not common to need changing. but the poblems that you mention (sunroof, windows, radio, cruise control, and steering wheel controls,) are all controlled by a system GM calls R.A.P retained accessory power. there is a relay for this behind glove box,. this relay gets its power from the fuse box in the dash. fuse is inadv power bus/rap fuse. this controls the relay. IGN 1 fuse 50A under hood is the power that is switched with it. The BCM does ground out this relay to make it all work.
if you check on the BCM you will find Orange wires in end plug. Test for power they should all read 12 volts. I will almost bet you that the Orange wire at pin K will be dead. that is the inadv power bus/rap, circuit. if there is no power here but fuse is good check for power at fuse. or you can connect a fuse holder with 15 am fuse from BCM pin J to K and presto you should have everything back.
Someone's going to have to find a short, open or defective component that's temperature dependent. You can go out with your multi-meter when it's cold and not working or the tech can do it. It's not fun, and it's often not cheap. Since the radio and sunroof aren't really related, I'd start looking for a bad ground somewhere. There should be a fairly heavy wire somewhere connecting the body to the engine or chassis. Look underneath and around the back of the engine compartment. If you can find it readily, make sure it is intact and has nice bright connections. (take the ends off and clean them with a wire brush, if you doubt the wire at all, replace it.)
Not positive it is the same thing, however, when setting up my iPOD adapter to the radio, I made the mistake of not following the instructions to the T, and it caused my sunroof to stop working... after a day (which I later found out gave the system enough time to "reset" and connect), I turned on my stereo, pushed the 3CH to Dolby Surround, and that did the trick. It's been about a year... and I've had no problems with the sunroof!
check the fuse for the radio first. replace fuel filter. and get nuetral safety switch. radio adn sunroof might be related? hope this helps. fuel filter 10 dollars nuetral safety switch 30 dollars auto zone. easy fix.
