ford econoline flasher module

my left blinker stays solid all the time, so i went to schucks and go a new flasher module, but i have no idea where to install it to. can anyone help? thanks

*"go" should be "got" i found where to put it in, but my left blinker is still solid. anyone know what else could be wrong?

By solid, do you mean it doesn't flash? Check the bulbs front and back- if there isn't enough load to trip the flasher, it won't work. I'll hazard a guess and say the back one- have someone stand on the brakes, and check to see if your left rear lamp lights up. Also, make all the usual checks- sockets and wiring are still intact, the grounds are still OK, and so on.

If the lights are ok then it si probably the signal switch.

yes i do mean they dont flash. just the left signal though. the right one is fine. the brake lights work, and parking lights work, so im pretty sure its not the bulbs. if its the switch, wouldnt it just not turn on at all? I just did all the wiring checks, and everything seems fine. its both the front and the back signal flashers on the right, so im thinking its something internal more. any other suggestions? thanks
