2000 Astro Interior lights and window problems

[finemedic]

2000 Astro. After you turn off the engine the radio used to contiue to play, you were able to put the windows up until you opened the door. Now soon as you turn off the engine the radio turns off and you cannot put up the power windows. Also when you open any of the doors the interior lights do not come on. I can turn on the interior lights with the button on the dash by the headlights but it's still not working right! Please help it is driving me nuts!
Thanks,
Bill

Do you have the faqctory keyless entry? RKE?
if so... Here is how it is supposed to work

I'd check the RAP fuse first

Retained Accessory Power (RAP) Operation
The Retained Accessory Power (RAP) feature utilizes the Body Control Module (BCM) to control the operation of the Power Windows and the Radio. It also controls the operation of the Rear Radio Control and Overhead Console (if equipped). The RAP Relay is powered by the RAP Fuse, and controlled by the BCM. When the ignition switch is turned to the OFF position, the BCM supplies a ground to the coil side of the RAP Relay. This allows power to flow through the Relay to the listed systems. The BCM will turn off the RAP system by removing the ground path from the RAP Relay if any of the doors are opened, or after 20 minutes when the BCM times out.



Interior Lighting System Description
Vehicles with the optional remote keyless entry (RKE) system have interior lighting controlled by the body control module (BCM).

This vehicle uses a delayed interior lighting system.

The system functions as follows:

The dome lamps will illuminate when any door is opened.
The dome lamps will remain on for 20 seconds after the last door is closed.
The delay is canceled and the dome lamps will go out when the ignition switch is turned to the ON position.
The illuminated entry function will not operate when the dome lamp defeat switch is in the OFF position.
The interior lighting system is protected from battery rundown by the retained accessory power (RAP) system. The RAP system functions by shutting down interior lights after 10 minutes (when ignition is OFF).

Interior Lights Circuit Description
When the interior lamps circuits are closed/enabled, the courtesy lamp relay is activated by the two following coil circuits:

CKT 690 (GRY/BLK) which is the courtesy lamp enable output of the body control module (BCM) driving the coil side of the relay.
CKT 1732 (ORN) which is the coil output side of the relay going to the potential grounding switches/sources.
When the courtesy lamp relay is enabled, CKT 156 (WHT) (courtesy lamp output) is enabled by the closed contact at the relay and then grounded by CKT 750 (BLK) at G110.

Some of these circuits can also be activated with the headlamp and panel dimmer switch. When this happens, the coil output side of the inadvertent power relay is grounded to the body control module (BCM) via CKT 1393 (DK BLU)

CKT 40 (ORN) from the courtesy fuse drives both input sides of the inadvertent power relay. When the contact is pulled closed, CKT 1732 (ORN) is supplied power, thus driving any lamps/circuits attached that circuit and providing ground.

The body control module (BCM) also monitors the following four door inputs:

CKT 49 (DK BLU) -- LH door jamb switch input
CKT 54 (ORN) -- RH door jamb switch input
CKT 775 (PNK) -- Side door jamb switch input
CKT 656 (YEL) -- Rear door jamb switch input/liftgate strut switch input (depending on option content)
When the doors are closed, the body control module (BCM) is in a floating state of 0-2 volts. When the doors are opened, the courtesy lamp relay is activated, sending power to the courtesy lamps.

The headlamp and panel dimmer switch also activates the following interior courtesy lamps when the switch is placed in the PARK or HEADLAMP ON positions:

RF power window switch
RH power door lock switch
LH power window switch
LH power door lock switch
LH outside rearview mirror control switch
Rear radio control head
The dome lamps can be disabled by closing the dome lamp defeat switch located on the headlamp and panel dimmer switch.

Yes that is exactly what is NOT working at the moment. Where is the RAP fuse? also the BCM? Also there is a Orange wire with a black connector on the end that was not plugged into the "fuse block" lack of right terimnology under the dash near the e-brake. I plugged it back in where it is suposed to go and light still do not work properly. We have a 2001 Astro at the firehouse and checked it and found out where the orange wire went. I will go back out and see if the orange wire is plugged in good. Thanks...please let me know where the fuses are for the RAP and the BCM are.

The RAP fuse is the 40 amp (big guy) labeled as RAP in the UNDERHOOD fuse block- second one from the end. also check the CTSY fuse at the IP (instrument panel) fuse block

Ok out at the garage now..Also another tid bit. While in the van engine running the power door lock on the drives door will not stay locked. Soon as you hit the lock button all the doors lock but the drivers door lock just pops back up.
Thanks for the help
