A1Auto parts saved me again!

Great part! Went in as shown in the video and works very smooth.

Mercury Grand Marquis GS 06, Front Driver Side Power Window Motor

I replaced my driver door window power motor using one that I bought from 1A auto. Perfect fit and works great. I followed their tutorial video on how to do It & it was easy to follow. It took me about 2 hours because I did not have the right size bolts (10 MM with locking washers) so I had to go to ACE hardware store. In my humble opinion, I don't think that you have to remove the rivets on the door handle lock portion to get the motor out. I could be wrong.

Good window motor regulator

Works good. It is a little louder than stock, but no issues.

Only half way down!

The fit was perfect, but it is on going half way down. I'm going to drill the rivets out again when the Temps are above freezing to make sure I have everything thing lined up. But right now I'm not happy.

Very pleased

Thank you for providing perfect video instructions for my replacement driver side power window. Very detailed information made it simple and most of all saved on repair at the dealership. Continue to share your knowledge how to videos. Appreciate all of your help.

Sloppy

Part arrived quickly. The part of the regulator that the window attaches to has some slop, so the window does not glide smoothly in its track when rolling up from a completely down position. I have to guide the window initially, or force the motor to work harder for the first few inches of roll up. My guess is that I'll be replacing the regulator in the near future.

Exact fit

I had to replace my driver's side regulator and 1-A Auto was an exact fit. Installed easily after watching the 1-A Auto installation video found on the you tube. Would purchase again if one of the others burns out.

What size nut and bolts replace the rivets?

Thank you for your question. It all depends on what size bit you use to drill them out, but we do not have exact specs for the nuts and bolts you will have to get.

Does this power window regulator come with screws? or I have to source them by myself?

I needed 2 extra bolts & nuts. All others were supplied with the motor / regulator.
