Drunken Little Green Men in my Sunroof

[BioBenz]

Hey All,
When I first start up the vehicle, I can open the sunroof with ease. It slides back quickly and without any fuss.

However, when the car has been running for some time, it becomes more difficult to operate the sunroof. If I try to close it, it will get stuck many times along the way, neccessitating a jogging of the switch, or a helping hand. This will occur if I then try to open it again.

My only conclusion: there are Drunken Little Green Men in my Sunroof having some sort of party. They obviously figure that one successful operation is enough for the day. Then they go nuts on my dime. Crazy little bastards.

Thanks in Advance,

BioBenz
