it would be nice if it was a 'standard Vanagon thing' ...
like low brake fluid, pressure failure warning coming from the brake light
switches,
or parking brake handle switch acting up ..
and I would check out all those carefully ...
and.....the 3,000 rpm thing ..
has me wondering what possible interface there could be between the Subaru
engine and electronics and that brake warning light ..
tachometer or VSS are the only things that remotely occur to me ...
also.."as soon as I brake or put the clutch in' ...
ah ha ..
cruise control ?
cruise control is involved with brake and clutch switches or vacuum valves..
if there is cruise control I'd explore that avenue .
and ..fwiw, not long ago I found a 'just plain faulty' brake warning light.
I was getting a vanagon alive again that had been dead for a couple of
years...
forget the exact symptom ..
warning light was on when it shouldn't be ..
and it was for sure, a faulty warning light .
it's not a simple light bulb, I think there's more to it than that I think
in that little part.
if there's cruise control and it can be disarmed by pulling a fuse ....etc..
I'd check into that.
that seems to me to be the most likely link between rpm, brake and clutch
pedal operation and that warning light.
