In a 1996 Chrysler Town & Country, the blower motor resistor is typically located
behind the glove box. However, accessing it can vary slightly depending on the trim level. You'll likely need to remove the glove box (or at least partially remove it) to reach the resistor.
Since your AC only runs at full speed, the resistor is a prime suspect. A faulty resistor prevents the blower motor from receiving the correct voltage for lower speeds. Replacing the resistor is usually a straightforward repair.
