Chad, I think I have some data on the system and will share it with you when I am back in town next week. I completely removed my system as Scrap described for a thorough cleaning and service. It was simple and done without surprises. One thing I recal was you should have the selector in a specific setting (full defrost ?) before dropping the assembly from the firewall. That is the piece I can't remember... More to follow,

I have a 2002 T2 in process of a garage/motorhome conversion. I have been lurking for some time now and find that I have learned a lot about the trucks b4 I purchased mine. Thanks for sharing the information that you do.
