A150 Window Switch Fault?!!

[swarner91]

Hi all,

I have a mercedes A150... all window switches are fine except the front drivers side window.. the window goes down fine.. if i tap the switch it will go down on its own as it should. when i want it to go back up, if i tap the switch it no longer goes back up on its own... if i hold the button the window will go back up as it should but once all the way up and i let go of the button it will go back down about 1/4 of the way on its own!!!

Anyone got any suggestions?!

Try lubricating the channels.
It sounds like it may be sticking.
