I have a 2000 Dodge Grand Caravan and when I turn the key on

Customer Question

I have a 2000 Dodge Grand Caravan and when I turn the key on the instrument cluster powers on but tach doesn't sense rpm's, and odometer doesn't work and then completely powers down in 5-6 seconds
JA: Is the car in "Park" or "Neutral?" Do you know if your car has a "wheel lock" feature?
Customer: It is in park and has no lock wheel feature
JA: Are you fixing your Grand Caravan yourself? What have you tried so far?
Customer: Yes I have checked fuses, ignition tumbler, ignition starter switch, and solder connections on back of instrument cluster
JA: Anything else you want the mechanic to know before I connect you?
Customer: Not sure

I think you have a body control module problem. you're going to need to take it to a shop that has an enhance diagnostic tool that can interrogate the body control modules.

Customer: replied 5 months ago.
That is the one next to the fuse block in the engine compartment
Expert:  david craig replied 5 months ago.

no. the body control module. is under the dash

Customer: replied 5 months ago.
No it's the one under dash right
