1992 SHO Taurus electrical burp

Hello.
My 92 SHO recently started acting a little strange. My airbag and antilock dash lights will flash or stay on, and the ac/heater panel will not work. It will occasionally flicker on, but quickly drops off. All other electrical functions appear to be ok. The radio, turn signals, headlights are all fine. Can I assume a faulty ground or fuse? Any advice would be appreciated before I give it a try.
