1999 Mercury Grand Marquis Front & Rear 4 Piece Power Power Window Motor & Regulator Assembly Set TRQ WRA51635

The parts fit perfectly and the motors are nice and strong. I like the fact that the rivet replacement Bolts were included.

We have been very satisfied with your oroducts. We have even ordered 2 more items. You get it to us very fast. Thanj you.

Drivers door was first. The holes didnt line up with the holes of the window, so tightening the bolts broke the window.

not very happy the motors on the regulators are very weak they will not make the window go all the way up on three out of four of the windows . Before I replace the motors I had two windows that just could not make the window go all the way up and one that was just stuck in the up position, after replacing all four motors and regulators I found that three out of four of the motors were just not strong enough to lift the windows all the way up. Before my driver side and passenger side front windows were getting stuck and shifting the window sideways after replacing the motors and regulators for the front windows the driver side now goes up and down no problem but the passenger side is so slow I think its going to get stuck every time. And the rear windows before one motor would not move at all and the other one would not go up all the way after replacing the rear motors the one that was stuck now goes up and down but the window falls out of position and it goes very slow and the other o

The drivers side works fine. The passenger front and rear dont seem to be working properly.

The product was an exact match, and watching the video on installation made the job easy. I wish that I didn't wait so long and did it sooner.
