The window on my 98ES 300 was stuck. Took it to Lexus and the estimate was about $600. Went to the local independent who specializes in Lexus-Toyota and the cost would be about $500. Must have hit a bump because now it works on its own. Could it be that all that was needed was a good kick or will it die soon? I'm not looking forward to spending all that money if it will continue working. All I use it for is paying tolls and the last time I did that was almost 4 months ago.
