on my 95 blazer for some reason the rear wiper does not work. i press the button near the headlights reading rear wiper and it makes a loud buzzing sound but the wiper does not work. any one have this problem or some tips? thanks.

 

check the fuse, the relay, and the motor. It may be dead.

Do the squirts work at all? good luck

 

The fuse is good, the motor is good, its just stripped. Mine is the same way. You got to replace the whole unit.
