Message Center Question

[HighRule]

I was reading up on the LS options and came across this "Bulb failure warning". Which is supposed to let you know when a light has burnt out. I've never had this message pop up and have had issues with my passenger side high beam. It seems if it's always blowing or I have a short. I've replaced the internal headlight wiring harness with my drivers side harness when I replaced my drives headlight assembly. That harness has never given me problems, so I was assuming it would give no problems on the passenger side.

Boy was I wrong. If the bulb isn't blown I must have a short somewhere before the headlight harness itself. How would I go about tracking this down? I will be doing my coils and other stuff tomorrow if there's no more snow and I wanted to do this at the same time. It could be the bulb, but my driver side is still working and was purchased as a two pack set.

I'm tired of replacing my lights. I buy a new set every time I have to replace the passenger one. Therefore, I have an extra "good" one laying around. I just thought I would check for a short to be on the safe side, to see if that is causing my passenger bulb to blow.

Sorry for the long post for such a SHORT topic.............LMAO see what I did there? Man I'm tired. :sleep:

I'm not entirely certain a short would cause the bulb to fail. More likely, you'd be blowing the fuse.

Does that bulb fit as snug as the others? Is the shield deformed at all such that it can touch the bulb? Extra vibration will kill halogens. BTW, is it halogen or HID? I assume halogen.

Good advice. Even with factory HIDs, the high beams are still halogen.

Does that particular high beam bulb seem dim when it is powered? I've seen several times where a power or ground partially rubbed through or broken will cause a bulb to prematurally fail. It was enough of an issue in my field that it caused a service bulletin for the trucks we work on. The easiest way to determin if you have this issue, would be to load test the wires. You can do this using the bulb. Plug the bulb in and turn on the high beam. Check the voltage accross the bulb. Measure the hot side to chassis ground, and ground side to a known good power source in the fuse panel. remove the bulb and test the voltage again. With the bulb in place, you should have had a minimal voltage drop compared to your test without the bulb. If you are seeing a drop of a volt or more, then one of the wires is bad. You test the hot and ground seperate like I described to determin if it is on the ground or positive wire.

The information center, at least for my LS, will not tell you when a high beam bulb is out. I know it does turn signals, brake lights, tail lights and I think the low beams.

For those with HIDs, it doesn't pickup low beam failures either.

Thanks guys. I wasn't able to do anything on it today. Hopefully tomorrow.

I've had my low beams and fogs go out and still never received a message same with highs. I haven't had a turn or brake tail lights go out yet.

When you hit status, it cycles through several bulb okay messages. I think that it names all the bulbs that it checks, so any unmentioned ones (like high beams) aren't checked/monitored.

LOL. At one point I've had both fogs, 1 low and 1 high out at the same time. I checked that "status" thing and it said all was good. Lol I'll hopefully get this solved tomorrow (hopping it's another blown bulb, so I can return it)

Fogs, Hi-Beam, Low-Beam (for HID anyways), License plate, Reverse lights - are all the exterior bulbs not checked.
