You should be able to find info on troubleshooting the controls, resistor and motor on this site. I'm not sure if the blower problems and water leakage problems are related, but it's possible. How many VX'ers have had blower and water leak problems? Should we start a poll?
For all the problems that are posted, I think related posts should indicate the model year and mileage when problem was first noted. Then we could track them and see if a pattern developes.
