1995 Toyota Camry High Beam Does Work Anymore Still Low Beam Also Flash

my high beam does not work anymore. I still have low beam. also, the flash switch works, when you pull it the high beam flashes as it should. sometimes I can leave the light switch in high beam position, although they're not on high beam, next time I start the engine (some ot the time),the lights will burn high beam and stay on. Once I turn high beam off, and try and turn high beam back on, they won't switch back to high beam. Fuses all seem ok.

Any suggestions?................Robert
