Headlights flash when I drive...
 

There's a problem on my 95 Blazer 4x4. When I drive by night, when I put the hi-beams, they start to flash after 10 minutes... If I stay in low beams there is no problem.

When it flashes I can hear a relay on the right, and I see a blue light on the cluster.

Anybody knows what's the problem ?

When they start to flash if pull the multi function switch to the high beam flash position and hold it will they stop flashing?

I don't remember :p !
But when I try to switch several times, the low beam flashes too.... But it's random...

Oh I forgot to say my multifunction switch is new !

Ah oui! Multi-function, why did you replace in the first place?

I've replaced the multifunction because brake lights didn't work.

Maybe the relay overheats ?

Not positive your 95 has a headlamp relay. Does anyone else know? I think its wired straight through the multi-function but not sure.

No relay. Only for DRl and fog lamps.

I would suggest check wiring.
The Light green wire is the power for your high beams. It is shared by both lights.

Oh almost forgot, the headlight switch can also do this.

Thanks for the video ! I'll check my switch...
