I need the BCM diagram for a 2000 Grand Caravan.
I have a short , all the gauges stop working but the tachometer.
it keeps blowing the fuse.

 

This may help...
SELF DIAGNOSTIC TEST
To activate self diagnostic program:

With the ignition switch in the OFF position, depress the TRIP and RESET buttons.
While holding the TRIP and RESET button turn the ignition switch to the ON position.
Continue to hold the TRIP and RESET buttons until the word CODE appears in the odometer windows (about five seconds) then release the buttons. If a problem exists, the system will display Diagnostic Trouble Codes (DTC's) If no problem exists, the code 999 (End Test) will momentarily appear

just found some more info that might help.
INSTRUMENT CLUSTER DTC TABLE
DTC DESCRIPTION
110 MEMORY FAULT IN CLUSTER
111 CALIBRATION FAULT IN CLUSTER
905 NO CCD BUS MESSAGES FROM TCM
921 ODOMETER FAULT FROM BCM
940 NO CCD BUS MESSAGES FROM PCM
999 END OF CODES

DIM TEST
When CHEC-0 is displayed in the odometer window, the cluster's vacuum fluorescent (VF) displays will dim down. If the VF display brightness does no change, a problem exists in the cluster.

CLUSTER CALIBRATION TABLE
Speedometer
1 0 mph (0 Km/h)
2 20 mph (40 Km/h)
3 55 mph (80 Km/h)
4 75 mph (120 Km/h)

Tachometer
1 0 rpm
2 1000 rpm
3 3000 rpm
4 6000 rpm

Fuel Gauge
1 Empty (E)
2 1/8 Filled
3 1/4 Filled
4 Full (F)

Temperature Gauge
1 Cold (C)
2 Low Normal
3 High Normal
4 Hot (H)

CALIBRATION TEST
When CHEC-1 is displayed in the odometer window, each of the cluster's gauge pointers will move sequentially through each calibration point. The Calibration Table contains the proper calibration points for each gauge. If the gauge pointers are not calibrated, a problem exists in the cluster. If any gauge is out of calibration it will have to be calibrated using a DRB lllĀ® scan tool. Refer to the proper Body Diagnostic Procedure Manual for calibration procedures.

ODOMETER SEGMENT TEST
When CHEC-2 is displayed in the odometer window, each digit of the odometer will illuminate sequentially. If a segment in the odometer does not illuminate normally, a problem exists in the display.

ELECTRONIC TRANSMISSION RANGE INDICATOR SEGMENT TEST
When CHEC-3 is displayed in the odometer window, each segment of the transmission range indicator will illuminate sequentially. If a segment in the transmission range indicator does not illuminate normally, a problem exists in the display board.

CONDITIONS
Refer to the following tables:

Instrument Cluster
Speedometer
Tachometer
Fuel Gauge
Temperature Gauge
Odometer
Electronic Transmission Range Indicator (PRND3L) or (PRND1234-Autostick equipped)
Mechanical Transmission Range Indicator (PRND21)

thanks parts/service for the info.
Now, the codes I got was 23 & 55. According to my notes 23 is "intake air temp sensor out of range" and 55 means "end of error messages". (correct me if I'm wrong).
this leaves me with more questions than anwsers, what the "intake air temp sensor" has to do with the gauges on my dashboard?
How come it's keep blowing the fuse if the BCM is OK?
could be one thing related to the other?
