On my Buick the door locks, windows, gas gauge, RPM gauge will not work. Someone told me I may need a Body Control Module. Could you please tell me where it is located
Have a good automotive electrical shop check it out for you.
Check under the dash near park brake brake.
No, it's right above the fuse box on the passenger side floor board, inside the center console. You have to remove the top of the center console to get to it. It's a PITA.

No, there is not a fuse for this. Unfortunately, you have a bad sending unit. In order to replace the sending unit you have to drop the gas tank. Sooo............drive it more to get rid of all of that gas and it will be easier to put back up.
please remember to rate this solution.

Hello, I work for a GM dealer in Texas. I have seen this issue a couple of times, on your model and several times on the Trail Blazer. That vehicle has a cassette type ignition switch, that have had some issues. It can lose one leg of the switch intermittently and cause several things to go nuts. I just looked on our service site and there are no bulletins related to the issue. If you know a tech at a dealership, have him scan the vehicle for codes and send them to me. Also ask him to check the power mode operation on the scanner, It will let you know for sure if it is a ignition switch.The switch is easy to change and costs about $35 so it is not going to break the bank. Electrical problems are difficult to diagnose at best but really hard not being there to do the testing. If you can give me any codes/ power mode info I will be better able to help you. Good Luck

BCM --The Body Control Module is located on the right side of the vehicle and positioned under the instrument panel. In order to gain access to the module, it will be necessary to first remove the trim panel.

If all power devices stopped at the same time you may have a bad fuse link. Since it is rare for all the fuses blowing at once and you already checked them. Start at your fuse links before assuming something expensive.
SOURCE: Buick Rendezvous 2002 need codes?
the BCM needs to be programmed to operate the computer. a GM techII is now required to calibrate BCM to airbag, stereo, keyless entry, and control pcm data. This is required to make it all work. a gm service should have it done within an hour or less just call and ask them how much it would be to program new BCM. it might cost @$75 to $125 but it is needed, to allow the BCM to work properly.
Testimonial: "ok...i bought the bcm on line (used)...but the gays in the dealer says i have to buy a new one..because the used cannot be to reflashed...or recoded."

Door lock system fuse into the BCM (BCM D 25A fuse)
Door Lock Operation
When the BCM detects a transition of either of the door lock switches to the LOCK position, it switches the door lock actuator lock control circuit to voltage. Since the lock actuator unlock control circuits are at ground potential within the BCM, the door lock actuator motors transition to the Lock position.
Driver Door Unlock Operation
When the BCM detects a transition of either of the door lock switches to the UNLOCK position, it switches the driver door lock actuator unlock control circuit to voltage. Since the door lock actuator lock control circuit is at ground potential within the BCM, the LF door lock actuator motor transitions to the Unlock position.
The driver door lock actuator unlock control circuit is a dedicated control circuit used only for the driver door lock actuator motor. This is done so that the driver door may be unlocked by itself using a keyless entry transmitter or an automatic door unlock function (if programmed).
Passenger Door Unlock Operation
When the BCM detects a transition of either of the door lock switches to the UNLOCK position, it switches the door lock actuator unlock control circuits to voltage. Since the door lock actuator lock control circuit is at ground potential within the BCM, the passenger door lock actuator motors transition to the Unlock position.
The door lock actuator unlock control circuits are dedicated control circuits used only for the passenger door lock actuator motors. This is done so that the driver door may be unlocked seperate from the passenger doors using a keyless entry transmitter or an automatic door unlock function (if programmed). This video on testing computer controlled door locks on a Subaru , doesn't matter . test yours same way > The BCM controls your door locks .
Are all of the power door locks inoperative from both door lock switches?
