Part # and price for BCM 1997 dodge caravan elect

You'll have to call local dealer, or if you want to take a chance with used at auto wreckers, it will have to be exact same part number, but personally I don't recommend that. Here's a number to call for rebuilt BCM's gauranteed, that will, if nothing else give you another option. New is probably $800- $1000 unfortunately. 1-877-388-5889.

There is always a chance that removing connectors attached to it, and cleaning well with contact cleaner or electrical cleaner (tuner spray cleaner from radio shack) may jsut be a cure if your lucky as well. I certainly would try that before spending that kind of money on a new module.
