Looked at the pictures again, need to check at the firewall, not the plug end - will update later 8^)

Blower stopped. 7degF outside - great. 30A fuse OK, #7 fuse OK. Checked three prong connector, no 12V at red, no 1-6V at yellow. CCU is switching the flaps OK (diverts air to defrost at highway speed, for example).

Any tips before I take out the PB unit, or anyone in Indy area have a PB unit I can try before going that route? I've had so-so luck with the joint soldering thing -

Thanks in advance for any wisdom -
