One of your courtesy light switch's is defective, it can be in any of the five doors (rear hatch has 2), Ford can determine which one (courtesy light switch) is at fault by using a NGS (New Gen Star Tester) to monitor the switches through the Generic Electronic Module of your truck, these switches are attached to the door latch assembly and are time consuming to replace, so the Ford tester is the cheapest option.

U must remove the entire dash assembly and then the heater core housing which is part of the air distribution box, time to do the job 10-15 hours.

if the heater core is getting hot then the problem is the air temp control blend door actuator, a common problem.

the little orange or red ring around the air hose whare it goes in compressor, must be pushed in while pulling out on air line. a small flathead screwdriver works fine

The fan assembly is attached using either small bolts or clips. in some cases you will have to remove the upper radiator hose to allow the fan to come out the top. just simply remove the top bolts and the hose and the fan should slide right out.
