Window auto up fault. Not stopping correctly

[Silverman]

Hi guys. I have a 2003 import. The passenger side auto up works great and seals perfectly but the drivers side window goes up to top but then comes down again about 2 inches before it stops. It’s really annoying. I have to stop it just before it seals to make it look closed but I get condensation because it’s not making a seal

 

Any idea how how I can repair this fault please? 

 

Thanks
