Subaru 4wd Malfunction

The push botton 4wd on my 1994 Subaru Loyale has decided not to work this season, or at least the indicator does not light up and she’s lacking some traction. The only fuse I found says “4wd AT” (automatic transmission? mine’s a manual) and it does not appear to be blown. If anyone out there in has any advice on what the problem might be or a solution, it would be greatly appreciated, thanks.

Try where they live and breath Subaru.

Thanks, looks promising.
