What is wrong with my ex?

My 2000 ford excursion has been giving me some problems lately. It has 138000 miles and has never had a problem until now. It started a few weeks ago with the ignition lock got stuck and i had to force it to turn. Then it take like five turns to get it to start i can hear a clicking under the ignition? So i dealt with that for a few weeks no big deal. I go for drive and notice my radio getting dim and the truck just dies. First thing i think is battery then alternator got a new battery and alternator, hooked up the new battery checked voltage and waaallaa the alternator is charging so i am stumped. The next day drove it around town and everything was good i thought. Wake up next am to a brand new dead battery. So i jump truck alternator is good battery is fully charged again and was good for a couple days. Im driving home from work and notice speedo bouncing around then go out completely and od light blinking as well as airbag light on. Turn it off and go its fine let it go another day and today i shut it off i can hear beeeping sound when door is open and key is in only thing was is key was in my hand and the ac was still on and i put it in off pos it went to the floor weird. My ideas i think are ignition switch or lock and tumbler any insight would be greatly appreciated. thank you

Check your fuse box and the nearby GEM for wetness, you may have a leaky windshield.

Also check the wires under the column cover for the infamous chaffed wires. Here is a link to the thread. https://www.ford-trucks.com/forums/7...uestion-3.html

The one you need to check is next to the fuse box.
When you checked, what was the condition? Wet or dry? Clean or rusty and dirty?

Ok.

With a diesel, it's always better to replace both batteries at the same time. I saw where you said you only replaced one, so, not knowing if you had a diesel or not, I couldn't recommend replacing the second battery until I found out which engine you have.

Just a wild guess, but might want to check grounds connections.

Sounds like your ignition switch. I know on older Fords there is a rod from the lock cylinder to the switch, sometimes they bind and maybe yours bent by forcing it. Sometimes the contacts in the switch melt, might be why it's in acc with the key out and draining the batteries. Easy enough to check anyway.

The drawings do not paste so here's the best I could do.

Generic Electronic Module (GEM) —Generic Electronic/Central Timer (GEM/CTM)
Removal

NOTE: The GEM must be reconfigured upon replacement. Refer to the scan tool help screen on the Ford Service Function (FSF) card to program tire size and axle ratio.

CAUTION: Electronic modules are sensitive to electrical charges. If exposed to these charges, damage may result.

Disconnect the battery ground cable. For additional information, refer to Section 414-01 .
CAUTION: Use care when removing the instrument panel steering column cover (044F08) or damage to the cover locating tab may occur.

Remove the instrument panel steering column cover.
Unlock the retainers.
Remove the instrument panel steering column cover.

Disconnect the bulkhead connectors from the instrument panel fuse junction panel.
Loosen the bolts.
Disconnect the bulkhead connectors.

Position the instrument panel fuse junction panel aside.
Remove the nuts.
Remove the bolts.

Remove the generic electronic module/central timer module (GEM/CTM).
Disconnect the electrical connectors.
Remove the screws.
Remove the GEM/CTM.

To install, reverse the removal procedure.
