Welcome aboard!!
I would start by checking all the fuses under the dash on the driver's side and under the hood.
I had similar electrical issues with my 02 xlt. The dome lights would stay on until the battery saver feature turned them off, the driver side puddle light didn't work, the keypad on the door would set off the alarm when I pressed it, the door ajar light would flash and beep at highway speeds, the radio would shut off as soon as I turned the key off, etc. Most recently all 4 windows stopped working.
A lot of electrical issues can be traced back to broken/damaged wire(s) in the boot between the body and the driver's door. I found 2 broken wires and repaired them. The thin black ground wire was broken and after repairing it all was back to normal.
When the windows stopped working, I repaired the thick black ground wire and the windows now work like a champ.
Here is the thread for removing the door panel:

Be sure to take your time when looking for broken/damaged wire(s). When you think you're done looking, look again, and again, and again. A bright flashlight can be very helpful.
