high beam not staying on

Hi guys bit off a strange question I cant fiqure out
Ive recently replaced my front inner archs
And dont know if thats got out to do with it but now my high beam wont stay on when I pull the stalk back
Example being
-low beam is on
-flashing high beam works
-if I pull the stalk all way back it turns off low beam onto side lights but high beam should be on and the light on dash isnt on ever

But flashing high beam works

Any idea guys
cheers

You may have dislodged a wire or trapped one.

Otherwise I'd say it was either your switch or dim dip relay with the switch being the most likely

Pritty sure it worked fine up untill I took it all apart for the archs
The thing is the switch is kinda working as its making it go on side lights
