1999 Saab 9-5 SE

1999 Saab 9-5 SE Blower Motor Heater was only operating occasionally. When I got to the Blower Motor, discovered that the connection is faulty on the actual Blower Motor. In other words when I press and move the connector around the blower starts right up, turn off the car, on again, sometimes starts sometimes does not, but can restart the blower by moving the connector around. How would I repair the connection on the Blower Motor itself? Thanks.
