I have an '05 LS sedan and it has an annoying rattle which sounds like it's coming from the rear passenger side of the car. I've done some reading but haven't found anything worth following up on. I have GM full shop manuals and going into the rear decklid involves disabling the SIR so I don't want to fool around with the crash sensor in that area unless absolutely necessary.

I also noticed that some of the bulbs don't light anymore on my heater/temp/air direction controller board. The bulbs are not replaceable unless you know how to solder. I grabbed a new board from the wrecker and the same bulbs don't light up. Any ideas? I have a picture on my web page - go to the bottom and then scroll up. I have checkmarks on the bulbs that light up. I use the fan controller a lot because it allows me to achieve a lower idle when the fan is off and I'm sitting at a light. Yes, I'm a hypermiler.

Welcome to the forum.

Frankly I'm too afraid to click on that link. With all due respect, in this day and age it's not cool to invite folks to visit a website you set up on your PC. Hackers can easily hijack your website and use it for their purposes. Plus, your ISP may not appreciate it. Could you please upload your images to photobucket or something?

It's definitely not the spare cover. After doing some reading yesterday, some people mentioned the child restraints in the rear, speakers, and possibly the rear defrost relay. Here's the pic of the heater controller too. I'm hoping I can use normal leds in there since they actually look like minibulbs that have a filament with a blue rubber cover.

I don't know if you've tried sitting in the back with someone else driving but I highly recommend it. On the bulbs, you'll probably want to make sure they are out vs. not getting power. Beware that these things are tied to the instrument illumination, i.e., get variable voltage.
