1995 Saturn SL2 Blinkers work sometimes

When it is cold outside my blinkers will come on when they want to. I have checked the fuses and used a voltmeter to check them. The voltmeter reads 10 when the blinkers quit working and it is attached to the fuse. The fuse is not blown and I don't have any idea what else it could be. My bulbs all work and my brake lights and turn signals flash when they are engaged until they stop blinking on the dash.
