Rears are working, both flash cans seem to be blinking ok, but no dash turn indicators and no fronts. 12v idiot light shows no power to sockets either.
No power at the connectors in the engine compartment. The wires go right into a wrapped loom after the connectors in the engine compartment so I'm not sure where else to check.
Any ideas?

Thanks!

What kind if dash do you have? Was it ever converted? For the front turn signals to work, power leaves the column through a 20g DBL and a 20g LBL and goes to dash turn indicators and then to fronts. Check for power on these 2 wires at the column first, with key on and turn signals on. ( if using a test light, light will flash)
