I have a 1998 Blazer with the typical windshield wiper problem. Of
course Chevrolet denies that the 98's and 99's have this problem.

cover has 4 screws. One in each corner. The bottom right screw is
I'm wondering if the 98-99 models have a different unit and that's why
Chevy is pretending that there is no problem.
