98 Voyager turn signals work intermittently

Hello all
I just bought a 98 Voyager LE and after a few days the left turn signals started to work intermittently (They work only occassionally). Also keeps blowing the front turn light. Not sure where to look for the electrical problem. Any help?

first of all the bulb has to be seated in the lamp properly to seal off any water or debri from it and i would wiggle the signal flasher under the dash when the signal lamps quit this a common fault with these vans
