Glove box light on timer?
I usually have my 2002 C5 covered under my carport at night but decided to leave it off tonight to do some work on it tomorrow. I walked out to let the dog out and went over to make sure I had locked it and after using the fob to lock it I noticed a faint glare inside. On further inspection I could tell that the light was coming from inside the glove box. What the he**!?
First off, why would anyone need a light on once you have LOCKED the car,especially the GB light? Is this preprogrammed in the computer?
I put the dog in and walked back outside to see if it was still on(about 3 minutes) and it apparently went out on it's own. Has anyone else noticed this phenomena and can it be programmed NOT to come on short of removing the bulb? Just thought this was a little wierd.
I love my car though regardless of how wierd it gets

The glove box light should go off when you close the glove box. If it doesn't you need to adjust the switch or door. It's not exactly on a timer, but will eventually time out and go off as part of the battery protection circuit. It should not stay on anytime the glove box is closed.

Good luck with the adjustment.

I agree the switch needs adjusting, but actually that light is on a timer, along with all the rest of the interior lighting. The timing is done by a "Monitored Load" circuit in the BCM and starts timing when the key gets removed (or turned to off). IIRC, it "times-out" after about 15-20 minutes or so.

There is a Monitored Load relay and fuse in the circuit as well.
There is a description of the "Inadvertent Load Control" function not only in the FSM, but in the OM as well. In my particular OM it's on pg 2-54.

I added some decals to the interior today and while I was at it I timed how long it took for the GB light to go out on it's own. Right at 8 minutes. I noticed that the door was hanging out when latched just enough to not engage the small plunger to cut the light off so I did what someone else in the forum suggested--I velcroed a small piece of plastic about an inch square in the spot where the plunger hits and ta-da, no more light when I shut the door. I've yet to find a problem that I can't find a solution to on this forum.. You guys rock!

That's one easy fix for the glovebox door switch. 
I fixed mine by using one of those small stick-on rubber bumper "feet" you can buy at Office Depot (the flat ones, not the round "bump" shaped ones). They're about 7/16" in diameter and maybe 1/8" I think. Works like a charm.

It's referred to as "Battery Run Down Protection" im the owners manual for my 04 and it's VERY briefly described in my OM on page 3-18. Not nearly enough detail to answer questions about it's operation.
I suspect there is a better description in the FSM but damned if I can find it!!

Inadvertent Load Control
You vehicle has a feature to help prevent you from draining the battery in case the underhood lamp, vanity mirror lamps, cargo lamps, reading lamps, console or glove box lamps are accidentally left on. If you leave any of these lamps on, they will automatically time out after 15 minutes. To reset it, all of the above lamps must be turned off or the ignition key must be in ON.

If you leave any of these lamps on, they will automatically time out after 15 minutes. To reset it, all of the above lamps must be turned off or the ignition key must be in ON.
For example, for the glovebox light:
"I/P Compartment Lamp (Glovebox)
Voltage is supplied to the I/P Compartment lamp from CKT 640. CKT 640 receives battery voltage when the MONITORED LD Micro Relay #43 has closed its contact switch. The opening and closing of the MONITORED LD Micro Relay #43 is controlled by the BCM through CKT 1393. The BCM will ground CKT 1393 under normal operating conditions and energize the relay which in turn energizes CKT 640. Battery voltage is then supplied to the I/P Compartment Lamp and it becomes functional. The BCM will monitor CKT 640 at the BCM connector C2 terminal C4 for an inadvertent load. In the event that the I/P Compartment Lamp is inadvertently left ON, the BCM will remove the ground from CKT 1393 de-energizing the MONITORED LD Micro Relay #43 and removing battery voltage from CKT 640. This function is used to help prevent the battery from losing voltage over a period of time in the case of a load being left ON. The I/P Compartment Lamp is grounded by CKT 150 through Splice Pack #202 to G202."

Even in my '99 FSM, neither the terms "Inadvertent Load Control" or "Monitored Load" appear in the index in the back of each volume. I just remember having read it in the past when doing some work on my own car, but today I couldn't recall if it was in "Lighting" or "Electrical" so I had to dig it out and look.
