I'd say no on the fact that with the window sliding up and down it would wear out the grid on the inside of the window after a couple of years of use. Plus the wires leading to the glass would flex and break where it attaches. Heck, even on rear windows that only lift up like Trailblazers, newer tahoe's and burbs the lug that is soldered to the glass break way too easy.

I think Suburbans from 73-91 with barn doors had them as an option in the later years. Don't quote me on that though!
