Your manual should tell you that. Also check your brake light switch by the brake pedal. It also disengages the cruise. If it is bad the cruise will not work but the brake lights may still work.

Have seen this problem before. You need to look under dash at brake pedal and find a blue switch with plunger contacting pedal, disconnect connector and jump with a peice of wire and drive to see if cruise works and if it does replace deactivation switch this should get you going.

The blend door is stuck in cold position. That usually happens because the blend door actuator has failed.
You will need to test and replace the blend door actuator.
To replace the actuator you will need to take apart the dash and remove completely the instrument panel,d isconnect the connector, remove the four screws, remove the temperature blend door actuator and replace it.
The replacement is not a job for beginners, since you have to take apart the dash to access the actuator.

Does it only change when going uphill, or under heavy acceleration? Or is it just when ever it feels like it? Generally, it's vacuum controlled and on a Ford, loss of vacuum when accelerating or pulling a grade under heavy loads can be normal, causing the air to come out of the defrost. To answer your question, the blower door is located in the dash, generally behind the radio area.
