First post, first blazer!
I just bought my 99 blazer 2wd 4x4. Everything worked great on it, yesterday I tried to unlock all the doors from the inside door switch and nothing, pushed the little hatch button and nothing. Everything else works fine, the unlock on my remote unlocks my doors but not the hatch.

any ideas?????

 

You asked and Im not being a smart *** get a door that has the keylock.Seriously I have to do the samething.My door is locked I cant get it open either.

 

Instead of just giving up and putting on manual locks, I changed the fuse and it worked.

 

My locking mechnism on the hatch back is broke.
