Hello- I have a 1999 Suburban with hand crank windows. I am also too heavy a person to reach the hand crank comfortably. I plan on remedying this by installing aftermarket power window conversion kits, at least in the two front doors. Has anyone here already done this project? Can anyone offer advise as to finding a quality product? I would like it to be fairly bullet proof after install, not something that I will have to repair down the road. Product reviews? install advise? Thanks in advance.
