If your car really is a 2009 you should have the harman kardon system, was it taken out? The head unit doesn't say harman kardon on it, just the speaker grilles. You should have a small sub in the rear deck, you have nothing there now? I confused.

I can't offer any advice, but hope the images help.

I don't think that's silly at all, completely understandable.

Once you've drained the old oil and replaced the filter, there won't be enough of the old oil left to make a difference. With that said, I think you're worrying too much because there really isn't a bad oil he could've used, unless he went out of his way to do something stupid like use non-detergent oil. Having .2qt's of some "crappy" oil left in the engine when you're adding 4qt's of fresh oil is no big deal.

decided to take apart my glove box light tonight.. Pull out storage cubby above glove box, it just pulls right out. after you do that, remove the white connector the two hooks circled in red in picture 2 hold the glove box light in place, push those in and pry upwards on the places i circled in red in picture #1. if you rush this and break a snap, the black piece that holds the light is 66242AG06A. Don't ask how I know the part number. once you remove the glove box light assembly, it'll look like #3. you can just unhook the black piece that holds the light in place, and you can pry off the cover on the opposite side of the connector. once you unhook the cover, you will see what is shown in picture 4. apparently after you remove the door, theres nothing holding the circuit board in the plastic housing and it'll just fall out. once you take the circuit board out, or once it falls out onto your floor, you'll see what is shown in picture 5.

I don't recall seeing a crossover when i took my door panel off.

@ bowdoin college? wasn't me.. but i did an internship there for a few months and those names sound familiar.
