Is your vehicle a super cab or super crew. Is it the side window or the back window. Do you have sliding glass window. I know you said the slider which makes me think we are talking about the back glass I just want to verify. Also which area does it leak in

Here is a test turn your truck on and turn the air on PANEL HIGH FAN WARM air and have all the windows up and all the doors closed. Then get a spray bottle a fill it with real bubbly soapy water. Then spray all around the seals exterior on the back window on top of the window and around the cargo light if applicable. The soap will bubble when you hit your leak. If the window is leaking you can reseal it by removing it First remove the seat back and the trim around the c-pillars and the interior overhaed light then remove the nuts for the glass get some help.
