My 2000 sienna Le has developed an intermittent failure of the drivers side power window. It will stop a few inches from the top and will not work for a while. If I wait a bit it will go up a bit at a time. The last time it happened it was raining and my wife is not happy but does not trust my mechanic skills. Could this be the switch and not the motor on the window? Anyone else have this problem?
Also, I just had this van into the dealer at 97K for oil sludging and they replaced the valve guides. Is this a usual fix for this condition and should I consider synthetic oil from now on?
THis has been a great van and I would love to keep it to 200K.
Thank you.
