Heatermotor works but not

[Belgium R/T -68]

My heatermotor works when I run battery straight on the 3 pins on the heaterbox connection, one at a time gives me 3 different speeds but it wouldn't work from the switch in the dash.
No fuseproblem so can it be something wrong with my switch on the panel? It's a non AC.

BTW, first time I tried after restoration was finished and car started up there was a strange noice like a shortcut.

Sometimes cycling the switch many times clears the contacts. They flash over with oxidation from just sitting around too long. Try that first!
