My 93 ford explorer has a factory alarm. It went off this morning, 2am!!! in the rain. I tried the remote, nothing, tried the second remote, nothing. Honking and lights flashing, I disconnected the battery to calm the neighbors and hopefully reset everything. I also disconnected the horn. After reconnecting the battery, and waiting a few minutes, the alarm again triggered. Any help out there???? Please!!!

We've had exactly the same problem with a '94 Explorer--every time it rains. That's a heck of a lot in Memphis. We finally took the fuse out for the horn, but this week, we had so much rain, the battery went dead from a whole days of flashing lights. Even the dealer wasn't sure how to deal with this. Please email me if you come up with any solution.

Rain gets in near the bottom of the left rear window, above the area behind the panel where the jack is stored, just forward and above the rear windshield wiper tank. The water runs down onto the alarm control module circuit board. It caused the alarm to sound, door locks to open and close, headlights to stay on, and other odd things.

I have never found the source of the water, whether the window leaks or whether it just "sweats" and water runs behind the plastic intrior trim panel. You will probably see rusty stains around the area. Gently blowing out the area with a hair dryer is the short-term fix.

I repaired it by using duct tape to hold a piece of plastic sheeting to the inside of the body panel that then hangs over the module, diverting the drips. Do not cover the module tightly, it needs good air flow to stay cool.

My 1994 Ford Explorer just had the same alarm events several times today. I am a new auto tech, but had no idea where to start with this problem.

I opened the panel just as written above and YES!! rust and water on the controller panel. I followed the directions here and I am offering many thanks for this post and this forum!
