What's it called

I need to buy a part for my 1994 F-150. Most of the wires under the dash plug into it. It's under the dash about where the "hump" is. My electrician says it's gone bad and it's drawing the juice from my battery. He called it a light module, but there is no part by that name. He determined it by pulling the interior light fuse in the fuse box. Even when the door is closed, there is a draw from the battery. Pulling the light fuse stops the draw but he feels it's the module that the wires plug into as the culprit. Any opinions??

Photos needed. If it's on the transmission hump, it might be the airbag module. That's usually where manufactures put the airbag module.

No, not on the hump If we were doing coordinates it would be in line with the hump but under the dash. Think as longitude and latitude. sorry for the confusion. I think we need to remove this bad boy for pictures and part numbers.

This was just posted by Stevef22 in his thread

The only “light module” I see on fuse 8 is the warning/chime module.

I don’t think he meant sitting on the floor hump but rather above it under the dash.

I removed the chime. Going off for everything and driving me to the insane asylum. BTW--We are hearing a "tick" somewhere under the dash. The sound reminds me of the sound you hear where you activate the turn indicator and at the same speed. The key is off but you still hear it and I think it's related to that chime.

Doesnt mean one of the door switches isnt bad, has he also checked the courtesy/cargo lights outside, on roof, to see if they rusted/melted together, they have been known to drain a battery.

I had a "tick" in my '85. It was the fuel purge solenoid and the relay had gone bad, causing it to tick the battery down to nothing. The relay was well hidden behind the trim panel in the passenger foot well. Probably different in your truck.

Found it. It's called a remote keyless entry module. Part number f3vf-15k602-ac
Anyone ever had one go bad as in a short that's draining the battery?

That box has a bunch of small relays in it. I can definitely see those relays getting stuck and draining your battery down.

That could be. A little background might help. A few months ago I used the keyless entry to get in (duh). I noticed the passenger side did not respond. Removing the door panel revealed that the plastic vent that sits between the panel and the door had fallen into the mechanism that moves the rod up and down to open and close the lock. When I stuck my hand in there to remove the vent, the solenoid that moves the rod felt rough as if it had been burned. I'm just think that when the vent fell it caused the solenoid to fail and also the remote module was also affected. The power goes to the solenoid until it moves. If it does not move (jammed) it gets overheated and fails. Maybe? Perhaps?
