Well - perhaps we parts men
should stay out of the shop!

I couldn't even find the comm. port for the DRB. I unplugged and re-plugged in the coolant reservoir sensor, rad. fan control module, what looks like a sensor on the front of the right cylinder head. I doubt it any of that did anything good, but when I hooked the battery back up, the fan started going (but slowly, not full bore like before) and gradually slowed to a stop over about 45-60 seconds. Now it's fine. Dunno.
I'll see if our best electrical guy can have a look at it tomorrow and check for codes or something.
The A/C and recirc. buttons are still in-operative.
I'll let ya know what we find!
