Hello Guys and thank you for your time. My rear right side window went down by itself one day and would not go back up. Several days later I tried to put it up and it went up. Then a couple of weeks later it went down again and then went up several days later. Now again it went down and I'm am waiting the several days with high hopes it goes up before I take it to a mechanic. What could this be? I'm thinking the motor but not sure. Please help.

Thanks again and good Luck!
