In a 2002 Dodge Durango, the transfer case module is typically located on the driver's side of the vehicle, mounted on the transfer case itself. It's usually positioned towards the rear of the engine compartment, near the transmission area. For easier access, it may be necessary to lift the vehicle or remove protective covers. Always consult the vehicle's service manual for specific instructions.

The "voltage regulator" was a function controlled by the logic module in the 1987 SC. I think this was the case for 1985 as well. The logic module is located in the passenger side kick panel. A common problem with these cars was this function of the logic module being "fried" by a poor ground.
