There's a little dispute going on on another forum about the source of mileage data for the cluster odometer reading on an 05 Caravan. For years I've been thinking mileage data is stored in the BCM and if you change the cluster the odometer will read whatever the BCM tells it to. No reprogramming required. Is this in fact the case? To expand a tad, the BCM went away on the 5th gen vans. Is the TIPM now the mileage source and would a cluster change on a 5th gen van still be plug and play so to speak? One more thing. How do you send a private message on this forum? I'm lost.
