my blazho
mine is a 98 but I took the plastic off and 2 10mm bolts removed the motor from the tailgate and a adjustable wrench took off the large nut holding the wiper arm pivot on the outside, other then that lots of penetrate fluid inside the motor and worked it back and forth until the pivot slid out of the wiper motor housing, once out I cleaned it all up with a wire brush greased it and reinstalled it, did mine well over a year ago now and it still works
