Hi guys, this is actually my first post here, but I'm short on time at the moment and have to get straight to the point. I have a 2000 GTP w/ 152k miles. I have had alot of trouble with the blower motor(s). In '08 I replaced the old one which had worn out brushes. I also replaced the resistor module(the $250 one). It was all rusted out inside, odd for electronics. I installed a new blower March '08, which stopped working this May. I took it out, opened it up and the motor brushes were...rusty! If I put yet another blower in there, will it rust out too? How can I trace where, I assume, water must be coming from? Any ideas?

Thanks,
Chris.
