So I have a 1991 Legacy and today my temp and fuel gauges and the power windows quit working. The heater fan kept on working witch is a good thing cause the right window was down and it is 4 degrees out. any ideas on what it could be?

I've never looked at a legacy mechanically, much less the circuitry, but I'd start with the fuses and if no dice there, grab the multimeter and start tracing backwards. Maybe the other guys here have some better advice.

Well my Alt was not working, that's fixed but still my gages and window do not.
