I did a searchon topic but nothing came up like what i am experiencing on my XTS Platinum. When you first start the car the heater fan motor blows before the thermostat opens so the air is cold, so cold it freezes everyone in the car, Mt DTS doesn't do this; it just doen not blow at all until the thermostat opens. ON two seperate occasions two differnet techs have checked this and say that is normal. That I cannot beleive Caddy would make a system like that but they BOTH said everything is "working within specifications and paramaters". They said turn the heater OFF until the car warms up or use the remote start every time....Anyone else had this kind of a problem???
