Lighting Problem/2001 GT

[2001GTPEWTER]

Ok. After a little cosmetic workup I took my GT over to my local Exxon garage so they could inspect it for NY state. They told me I had a reverse light out, so I said "Go ahead and fix it". Now, (actually right after I left the garage) I notice that my dome light is out...and the new fog lights I just put in (connections are correct) arent working either. Whether Exxon did this on purpose (so I'd feel like I had to go back to them for more work) or not, I need to know where the problem is with these two lights. Obviously the headlights still work so it could'nt be a battery connection problem, but with these modular motors and tight engine housing I can't really get down in there and poke around real easy. Any ideas?
