My rear windshield wiper hasnt worked ssince I bought my blazer. It just doesnt move. I think its locked up and im not sure what to do.

 

its simple to replace just go on ebay and buy one
then there is 1 screw on each side of the tail gate you have to take off
then there is the one 2 in the handle
then there is multiple on the pannel underneath the nice plastic and carpet one
take them all out you will see the wiper motor with 2 bolts in it

from the outside

there is a rubber gromet take that out
theres a nut in there take that off
the wiper arm should come off
there should be a plastic nut under the wiper arm
then the wiper motor should come out (once wires are unhooked)
