i have an 02 f150 xlt v6 4x2, and when you roll down the passenger window it makes a slight clicking noise. does this mean the motor is going out, if so any idea how much would it cost to replace it thanks

 

you might try spraying the windwo track with a teflon spray. if thats not enough, take off the door plastic panel and grease the roller track that runs the window up and down. as long as the motor runs, you need to oil ot keep the lpading down so it dont overheat and burn up.
