Turn signal lamps light but won't blink. They were intermittant for a week and now won't blink. No turn indication on dash either. I have tried regular 1156/1157's and LED's (using Badlands ILL-01-A) and neither work. I checked the connections up to the Turn Signal Module and all looked good.
What should I check next? Should I just replace the TSM?

 

Did you check the ground to the lights

 

Where do I check that?

 

Hey man, have you made any progress here? Your thread came up while I was searching for my same problem.

 

His thread probably wasn't interesting enough, check your signal relay,they are cheap, check ground and all related wiring.
