We had a gentlemen with an older Mercury Grand Marquis stop buy with a driver door window problem. We brought it in to take a closer look and figure out his problem. Upon further inspection of the window regulators, one was making a crunching noise and the other was no longer operational. We took both of the door panels off to further diagnose the problem. Unfortunately as i assumed the cables had all bunched up in the one cogwheel and bound themselves together.
That was the popping noise we were hearing while the window was moving up and down. The photo above shows the wire that’s all bound up in the cogwheel housing. I put some supports in the door panel to hold the glass from falling down into the door panel or worse until we could get the new parts. We ordered new regulators assemblies and had them installed the very next day.
