I have a 2008 honda

odessy ex. My passenger side turn signal does not work and the hazard lights on the passenger side are also affected. Momentarily I was able to play with the right turn signal lever by switching it up and down and magically it started working again. But now the problem has reoccured and i am able to use passenger turn signal and passenger side hazards do not work. Any ideas? I heard turn signal switch is problem some fourm I read said relay switch. Please help?

Is that gray box the flash relay?
