Have 2000 RX300 with right front passenger window stuck in down position. Able to take door panel off and use motor with leverage to close window. Cleaned window but still has problem getting stuck when in down position. Current solution is to keep closed. It appears the motor works as the window does open and close intermittently. Not sure why window gets stuck in down postion. Other windows working fine. Any ideas?

New Member rquesting advice for 2000 RX300 FWD has 125K miles and mechanic states timing belt is overdue for repair. They recommend preventative add on repairs to include these parts/labor: 2 additional belts; water pump replacement (timing belt kit, with water pump); camshaft and crank oil seal replacement; Timing Belt Tensioner. Also, recommend spark plug replacement since they say it is overdue at 125K miles. My thought is just replace timing and drive belts (if needed) and check the water pump, cam seal, and idler to see if in need of replacement. I will hold off replacing spark plugs for now as they were replaced at 60K miles with iridium plugs. Bought the RX300 used in 2003 with 50K miles. Major repair has been the transmission replacement at 110K miles. What are your recommendations regarding the recommended preventative repairs? Thank You for your advice in advance.
