NO HEAT

Since I'm not sure if you bought yours used...
Have you checked if your heater core is getting engine coolant. Sometimes when a heater core develops a leak a lazy owner will bypass the heater core, or just disconnect it altogether.

It could be the blend door as Raoul suggested. This happened on my Escort because the temp control connecting rod was right next to the accelerator and it would get kicked off.
In my F-150, when I use the far right selection **** for the first time in the morning, I hear a banging sound when the air flow selection door moves into position. Something is sticking or there is no cushion or bumper to absorb the shock. Let us know what the problem is when you get it fixed.

I have heard two different things one. Ford screwed up in buinling the blend door too big for the hole causing it to stick to the housing (this could be your banging noise)and the second is that the computer that controlles this system is bad but the dealer does not know the part # to this box. It is behind the glove box and on top of the heater core housing.
