I recently purchased a 1997 blazer ls 4door 4wd and my dome lights and map lights are not working fuses on driver side fuse box are all good. Can't seem to get fuse relay box in glove box opened don't know if there is a special way to open or what. Also my power locks do not work at all. Please help if you can

 

Looks like you`ll have to take off the glove box door.That way you can get to the fuses.Usually the dome light and power locks work injunction together.GM made every year different from blazer to blazer or s10 to s10.I would take it to a mechanic that can fix anything.EX: my mechanic can take a vehicle apart down to the frame,then put it all bak together.Some mechanics have no clue when it comes to trouble shooting electrical problems.
