My high beam lights will not stay on. I can flash them! on 1994 Toyota Land Cruiser

The switch seems to work when flashing the high beam headlights, but they will not come on when I engage the high beam switch

Asked by for the 1994 Toyota Land Cruiser
Is likely a part of a multi function combination switch and will have to replace the whole switch or the half if can be seperated. The detent has failed and will not hold high beams on.
Thganks for your advise, does that mean I have to pull the stearing wheel to get at the
turn indicator?
