Interior lights power windows and rear wiper stopped working

It appears that all these are on a single fuse. Locate the fuse box under dash near the steering column and remove the cover. A fuse diagram will be on the back side of this cover and will tell you which fuse to replace. Owners manual will tell you the same.

These systems are controlled by the Generic Electronic Module (GEM), have a self test run on the system by Kragen, it is free, post codes here.

but most likely the Module is defective, it is located on top of the fuse panel to the left of the steering column. I have 30 years as a Ford tech so I am pretty darn sure of this diagnose.

This could be a combination of electrical issues, although i feel that the timing is coincidence in this case. When the combination is elec. windows, wipers, and dome lights this is indicative of the GEM module located behind your radio. The GEM (generic electronic module) is an electronic body control module that regulates electrical flow through a number of accessories. 

These factory module boards are notorious for acting quirky by failing to ground intermittently until failing completely. I would be cautious in replacing ignition switches, locks, etc. as the issue can be also compounded by corrosion of the main battery ground wire in the engine compartment and which can cause frying of your under dash wiring into the main wiring harness which can get expensive (i speak from experience having had the exact same syptoms). My issues were that these symptoms occurred only in full ON. When in key BACK ACC mode, they disappeared.

New price for one of these modules is around $280-$300 and easily replaced.
