Various intermitent problems

Well folks I have a '99 Stratus here that is giving me the run around. It's a finicky car that doesn't like giving me information sometimes. I'm still trying to pinpoint the exact times that it does it but it appears to not like the heat mostly. When it acts up I have no gauges whatsoever and the wipers don't work. The lighting all works still and the computer seems to maintain settings but throws no codes. Anyone have any ideas here?
