Check the ext temp sensor - it may be unplugged or just gone...
You can get to it by removing headlamp pod cover and the headlamp (then rotate down) or take off the wheel and remove the splash shield

Ahhh makes sense. Since the system is temp driven if I request 68* it's working like hell to get there and won't. I need to look at the schematics, I got the set on CD. :-)
Thanks!! That's the kind of help I need!
