window not working

[New2Ford]

My passenger window goes down to halfway and then almost stops. I usually have to help it down is there anything I can do to fix this. I would take in for warranty but I don't even know if its covered and I don't always have good luck with warranty. I changed the speakers on both front doors and I know they will say I messed with it.

I would double check that the tracks for the window are adjusted right. The rear track has a clip towards the top that somtimes gets popped out. If this is the case the window gets squeezed and binds-up.
