hey there..I was driving my car today with the window down. When i went to put the driver's side window up after i parked it and it didn't go up. i can hear the motor trying to go up (i think), but it just sat there about half way. so I was driving home and then it went from half up to all the way down...so i assume there is nothing holding it up. I was wondering how i can troubleshoot this and if anyone has an idea where i can start. I love driving with the windows down, but if there is some way I can get it up and to stay up even for the time being i'd be happy. I sure hope the parts are put in another vehicle and not $4000 just because its on a viper.
