2000 Blazer Power Locks, Mirrors, Rear Window Latch
I have a 2000 Chev Blazer, Yesterday my power locks, mirrors and rear window latch was working. Today it isn't!! My little girl pressed the rear latch button and since then nothing.... I've checked all fuses, everything seems good. I've changed over the main power module in the D/S door, (windows & power locks piece) still nothing.... I'm baffled, not a clue where to go to from there. However, there is no issues with the power windows or the window locking switch. Can anyone point me in the right direction?? Thanks!!!

Check the fuse in the Underhood Fuse Block (UBEC). The mirrors and door locks are on the same fuse there. In my 98 it's Fuse #7 (3A fuse). If that's blown replace it, but then you're going to have to do some troubleshooting to determine why it blew. That will mean you'll need a wiring diagram and most probably a multimeter. Just based off what you stated it could be a short in the circuit or switch for the rear hatch.

Rear window latch
I also have a 2000, if your daughter pushed the rear latch button and this happened take a small flat blade screwdriver and pop the switch out of the dash, it should also be your rear window wiper switch, no need to take dash apart and there are no screws, just pry at the bottom or the top and it will come out, (check to make sure plugs are all the way in) use the screw driver to release the tabs on the electrical connection, go to the wrecking yard and buy a used one and see what happens, maybe you even have a pull and save, I just bought one for $3.00 cause my lights inside mine were burned out. To change switch about 1 minute, watch a YouTube how to if needed, I am telling you it is easy. In the owners manual it shows fuse #14 for power locks in the interior fuse block, in the fuse relay center under the hood on drivers side it does show a 3amp fuse for mirrors and locks, look under the cover for placement no numbers on under hood box on a 2000. right next to that fuse is a circuit breaker for the rear lift glass and if all else fails. # on breaker is 12088567. If it were me I would check under hood fuses first, and get a used switch to try second, if the plugs came off back of switch you will know as soon as you pop the switch out. Good luck
