Maplight

[punkdu]

Hello to all thanks for viewing, today I was messing with my maplight in my 1999 Blazer and I poped off the plastic clear cover because some how there was a dead spider in it, so I removed the spider and went to pop it back on and now it wont go back in place. I looked to see if I had mabe broke the plastic nob if you will but I could see if I did. I than tried removing the whole module by removing the screen near the windshield and I could not get it to come attached from the roof. If I did break a peace on the module could I replace the whole thing, if so where do I get the part? Also does anyone have any suggestions?

Thanks
