Review on Dorman 740-664: Premium Front Driver Side Window Regulator for Ford/Mercury Models, Black - Top-Quality Replacement Part by Kevin Baker

Perfect for 2000 Mercury Grand Marquis and fast shipping. Let me tell you, it was heavy drilling of rivets connected and driven through the glass. So be careful, otherwise you will also buy glass. FYI, this part comes with door rivets but not 2.1" glass rivets. Once you've drilled out the rivets in the glass, remove the glass completely from the door so you can reinstall it without fear of breaking the glass. Other tips. Remove the motor from the door and install it into the assembly while it is outside the vehicle. The motor rotates 360 degrees, so you don't have to worry about having to raise or lower the motor gear somewhere to align the window. Align it with the triangle and screw it in place. Then rivet the assembly again. Ready
