New to the Forum. Bought a 2021 GT Convertible Premium 5.0 yesterday. On the way home from the Ford dealer I noticed the passenger power window going up and down about a 1/4 inch from the top. Pulled over and it stopped. It been doing it all day today randomly. Wanted to get some ideas before I take it to the dealer. Still under warranty. I read in a few threads the connectors could be corroded or loose causing it because poor connection. Wanted to get some thoughts.
