Oh me...isnt it always the simplest thing some times....glad you figured it out...
The blinkers not blinking is most likely due to the leds... you'll need resistors to make those work..
Do like tempest suggested..wire a 1157 bulb in place of the led and see if it works..thatll let you know for sure what the issue is
Still odd that the hazard would affect the running lights and dash lights...the hazards should be on the brake light circuit..
But would explain why the flasher relay was warm..and the LEDs wont pull enough resistance to make it flash so that would be easy to miss.
