audio, dome light problem

I just bought a 1999 blazer,it had the origional stereo in it. I replaced it with an aftermarket unit. now I noticed that my dome lights and the 2wd 4wd indicator light no longer function. I am not new to car stereo installation but have never had a problem like this before.any ideas?? thanks... Dave

You have shorted out a fuse or messed up the wiring someplace.
Check for 12 volts on both side of all fuses.
Check the wiring for shorts and being crossed and check all plug ins for being plugged in good.

it was a blown fuse..I missed it the first time but closer inspection revealed the problem. thanks for the reply.. dave

You are welcome and thanks for posting back how it went.
Glad you found it.
Sometimes hard to tell of fuse by looking at it.
I always like to check for 12 volts on both sides of them.
Good luck
