Shifter won't move on 1998 Buick Riviera

In the winter time, it is difficult to get the push button on the shifter to go down, to put the car into drive, reverse, etc. Sometimes it can take a half hour or so of pushing the button before it will finally go into gear. Anybody else have/had this problem?
