Hi John,
Based on your VIN that is the correct wiper module. I do not see an order for one in your order history, are you sure it was replaced before? If it was replaced before, then I would say your motor is probably pulling too many amps through the module and damaging it. I would highly recommend replacing the motor as well when you install a new module. When you place an order for the replacement module make sure you add the breaker to the order to prevent this from damaging it again. Here is a link to the product page W0007967-Kit with both the module and the breaker.
If you have a P32 the wiper control module would be part # 15598496
That being said, I believe the 2003 Bounder's were on W22 chassis, so if you could supply your VIN we can verify that for you.
