My passenger side window is getting slower to roll up. Started with it being a tenth of a second slower. Now I'm at about two seconds. It's only a matter of time before it stops all together.
Get some silicone spray lube, slip the red tube in place, roll glass half way or more down, use the tube to direct the spray into front and rear tracks and spray liberally. This way the lube runs down the tracks, it's OK if it drips out the door. A can should do 4 glasses / 8 tracks .... but it's OK if it only makes it through 2 doors 4 tracks.
If you want, hold a rag around the tube where it's inserted into the track to limit spray back.
Also, if you have applied window tint (film), you might have a problem if you use a lot. Just something to think about.
You may consider a new rail/actuator assembly as best way. Are the window seals wiping too tight? Window should slide up and down free if/when the glass is loose from the rail.
