Hello. It seems your Ford has a faulty master switch in the door panels (for the windows), a faulty door jamb switches (for the dome light), a malfunctioning multifunction switch (for the turn signal/windshield wipers). Good luck and keep me informed; if you want to.

Very common for the transmission range sensor to cause all these problems. I know it doesn't make sense but it's very common. Replace the range sensor and you'll be ok

a fuse or a bad wire

This car was in the flood of 08........................

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.

Good Luck

Hope this helps.

the wiring for the dome light, door ajar and radio is most likely crossed with the brake light wires causeing it to turn off power or on when pressing the brakes giving electricity to the lights and then it could be cutting off the power to the radio
