03 Explorer Electrical Problems

I’m having a bunch of electrical problems with my 03 Explorer V8:

1. Door Open Alarm – no amount of WD40 in the door handles will stop it.
2. Drivers Side seat position memory buttons not working
3. Automatic door locks (normally lock at about 8 mph) activate intermittently – sometimes after driving several miles
4. Drivers side electric door lock/unlock lever works when engine on but not when off
5. 2nd press on the lock button on the keyless remote causes 2 horn pulses instead of 1

Any clues if these symptoms point to a single failure point?

I also have transmission problems but the transmission shop suggested to clear up any electrical issues first.

Thanks for any insight.

Sounds like some loose connector or wiring or a defective controller.

Have you had any repairs done or installed any equipment lately?

Poor grounds are the most prevalent type of wiring problem. If anything has been disturbed, check there first.

Check the ground wires that go through the boot between the drivers door and doorjam - one might be frayed or broken. It might be making intermittent ground when the door is opened. It's a fairly common issue there as Ford didn't waste any extra wire in that harness, it gets stretched when the door is opened.
