W123 Coupe LH Rear Window Switch

Need help, why is it the when I push my window switch to go down the window goes up and when I push the window switch to go up the window goes down. However this only happens on the LH Rear switch all the others work normally. Has anyone else had this problem and how did you fix. Thanks in advance
