Driver's window rattles in both up and down positions. Passenger side does not rattle. I have heard this on multiple Chevy products. Any ideas what is causing the window to rattle so badly?

Answer 1

I don't know what year your Z is but I will guess it has the same problem my Z had. Remove the driver door panel and the sound insolation. There you will find the linkage for the door functions. The insulation used at the factory for the linkage has likely fallen off by now. I fix the rattle with wrap flew conduit. Also you will find that where the arm rest fasten to the door the mounting plate is rivited on. Oer time and a lot of pulling on the arm rest to close the door will stech the rivits. The mounting plate is no longer tight to the door panel and it rattles. Either rplace the rivits or do as I did. Add a small bead of silicon.
