I have a 2000 corolla with about 134k miles. I bought the car used with about 120k miles on it. Yeah the car still runs great though I just discovered while cleaning my car the surpentine belt under my hood looked a bit strange. I notice that on the outer side, I can see what appears several dirty white line that run the length of the belt. Since I bought this car, i have no idea when was the last belt change. Can anyone tell me if the white lines indicate a time for replacement? how much would such service cost me, ballpark figure.

Second question, is that the window on my front passgener side door sometimes roll down when i press the switch. I think the motor needs to be replaced. Anyone know where I can find a decent price on the motor (on the web) along with the instructions on how to replace it?

Aloha..thansk for any reply in advance
