hey guys i just bought a 01 blazer this week.and went to the carwash to vacuum it out and the hatch opened like 4 times prior to this.but when i got there i had my friend press the button and it poped once and it didnt open,now theres nothing.went to the junkyard and got a actuator and replaced it.didnt fix it.then tonight i relised my power mirrors aint working,are they on the same fuse.this is driving me CRAZYYY

 

Easy thing to do would be to check the fuses.
Next thing to do would be to measure the voltage at the rear window actuator connector.
Probably on the same fuse, but I do not have the wiring diagram to look at.

 

there is an override button on the dash, I haven't figured it out(haven't tried) but maybe you pressed it on accident.

 

if you're talking about the button by the headlight switch that for your dome light so it dont come on when your doors are open

 

same size button on other side of steering wheel it says rear hatch.

 

that's to open the hatch from inside the truck if you're talking about the one that's located on the same panel as the rear wiper switch
