Hello and welcome

On your turn signals,yes they should cancel after turning the steering wheel. Likely needs the switch replaced,the tangs are made of plastic that turns them off and they break.
On the wipers it could be a poor connection,broken wire,wired wrong. Did they work OK before restoration

Or did it just happen, more info needed
