left turn signals don't work or flash on dash. Module? or connection?

1. Have you checked to make sure that the bulbs are good? A bad bulb can keep the flasher from working.
2. If the bulbs are good check the switch, flasher and connections. Could be a bare wire grounding out, bad flasher or broken switch.

Let us know how you make out.

might be corrosion on the contacts, clean them really good and re-test

Thanks for the tips. Replaced bulbs. Still no lights. Also no brake light. Starting to think module. Any ideas??
