Thanks guys. Now that you mention it, it was more sticky than greasy, so I'm sure you're right about the tape.

Also, I didn't realize the ashtray had a light (just like I didn't realize the glove compartment had one until I found out about the lighter socket not working), so again I'm sure you're right about the light not being plugged in there.

I'll be sure to mention both the cleanup and the unplugged light when I take in back in on the 5th.

Thanks again!
