That much I understand.

I am under the hood constantly, I have not noticed anything leaking, dripping, smoking...nothing. I park in one of two parking spots, I would've noticed a new stain or something...

My guess is they could'nt find anything wrong with it but they know there is a problem and need more time to scratch their heads...

Have you recently stuffed the glove box with cd'* or anything? the actuator is located behind it.
When the you turn on the heat do the fans come on but blow cold?
To check the heater core just feel the incomming and outgoing hoses to the heater core, both should be hot.

not able to check any of those things at this point since the car is at the dealership, but as far as the fan is concerned...yes, blows cold... Nothing stuffed in the glove box...

Can only be 3 things;
Actuator,
Heater core,
Controller. (temp sesor must be good if blowing cold with ac on).

we'll wait and see

maybe we should change this to a poll!

I voted for #4 cause I know its true

On the other hand whats a Floridian need with a heater, like an Eskimo with a fridge?

ah come on, 33F is cold no matter where you live...unless you live in Canada...

update!

Service Desk guy says "intake" and that was all he offered as apperntly he is extremely busy cleaning out the Krispy Kreme tray and smoking his cigarettes....

I had a very minor coolant leak where the throttle body makes up to the upper intake. It was only a few drips under the throttle body every time start cold engine. It'* a very obscure area to observe coolant leaks, almost need an inspection mirror. There was a recall out by GM to replace the fasteners that connect TB to upper intake. I don't know if you vehicle was in that recall. Hope it'* not the internal leak on your intake, if in fact you do have a coolant leak.

Had the recall work already done. I have a funny story...right now good chance of "actuator" being the culprit, but I am going to wait until I have the car back (OVER 24 HOURS WITH NO CAR!!!!)
