Rep Power: 0

2005 coupe ex special edition 1.7
Intermittent high beams they work when they want.
Dash indicator does not function when lights are not.
Functions when they are.
Ohm'ed the red/blue 1Ohm
Have source voltage power and ground at the connector
Wiggle tested all the lines
looked for points of chaffed/damaged wire

If I pull either 15/17 20a mini blade the side connected functions but no dash light indicator
Ohm'ed the relay's low side 90 ohms activates when powered for both
Leaning towards the multifunction switch.
I only have a basic digram and no specs just been shooting for under .5 Ohms and source voltage.

I would say look at what resistance, or voltage that pin4 (BLU/RED) is at when the problem occurs.

Near 0 ohms (lights off) & near 0 volts ( lights on) when grounding path complete and high beams working

Flash feature work ??
