Same thing is happening to mine, except it is happening with both front drive and passenger side windows. Sometimes it wont go down and sometime it wont go up. Pisses me off. After clicking the button a few times it goes up. I dont want to take it to the dealer until it completely stops cause if I take donw there now and try to show them what its doing I know it wont do it and just make me look stupid. Oh Well, I still love this truck. I had a wierd dream that they recalled the TITAN. I hope this doesnt happen.
