Screeching window

My drivers side window lets out quite the screech when being opened. Suspect its a rock or something that is hitting the window. Any thoughts on how to get in there or clean out whatever is hitting the window without taking the whole panel apart. It's driving me a bit nuts

Kind of doubt that this would fall under my warranty?

 

um the only way to diagnose is disassemble door covers and get right in there

 

Any thoughts on warranty? I've still got a fair bit left

 

if it's dirt

you'll pay for it

tough call...pretty easy to take door apart all it takes is a screwdriver, spudger and spare time

 

Mine did that until I took off the door panel and put some graphite on the guide at the rear. Taking the panel off is easy. There is a video somewhere to show how (sorry, don't recall the link). The only problem with the video is that it features a shapely blond in a bikini, so I had to watch it several times to learn how the panel comes off.
