No, try finding a same year regal with at least 1 working window. Passenger side one is starting to scare me, but I should be safe cause my drivers switches are broke locking the others from any input. From the looks of it there was a design change on the motors. I did also notice these doors don't completely seal out water cause I found water in the front door speaker brackets 2 days after a rain storm. My last thought was lifting the back seat to see if it comes from the trunk area. There are little tabs to release the bottom cushion.
