confused High beam lamps will not shut off.

I have a 1996 explorer with the factory alarm. The high beam lamps came on in the middle of the night a few days ago and have been coming on every so often while driving or while parked.
Now heres the catch:
I have pulled the high beam relay, unpluged the module in the column and even pulled the high beam fuse but the lamps stay on. The electrical drawing I have shows that this is impossible.
I was wondering if there would be a wire from the alarm module that would be causing this or if anyone else is having the same problem.

I unplugged my daytime running lights module and that fixed the problem.

Re: High beam lamps will not shut off.

Mine was located in front of the left front tire behind the bumper. I had to lay down in front of the tire to get at it. Hope this helps.

Re: High beam lamps will not shut off.

My guess would be a sticky relay or water getting into the relay box. Is the cover on the relay box under the hood? Are all of your splash shields in place to prevent spray from getting into your engine bay?

You can test and check your relays here...

This is a link to a Nissan forum that I am on but the relays are basically the same for all cars. If they hesitate or stick then they need to be replaced right away.

I spent a lot of money on expensive ford relays that were just fine so don't waist your money unless you are sure. My problem turned out to be a faulty daytime running light module. Unpluging it fixed the problem. I just have to turn my headlights on when I drive now. The ford electrical diagrams do not show the module so it makes you think it may be a relay. This is a common problem with ford along with many other things.
ie. peeling paint, heater blending door failure, seatbelts releasing,....
No wonder these companys are in trouble. I personaly am getting sick of fixing substandard equipment.
