When I clean the glass there is a dull brown streak that appears on the glass and the windows struggle a little to go up. Sometimes it falls or pops 1 cm or so. All 4 windows started showing symptoms around the same time.

 

You got doo-doo in that door, dude.

 

Thread title like this just begs for it ......you have the classic Code brown skid marks and squeal! Trapped cat?
