Welcome to DF!

Ya it could be a bad ground or power source. It defiantly has something to do with something under the dash or steering column. Just diagnose one system at a time. Trace the power and ground and see when it stops.

If needed we have the service manual in the FAQ in this section. It has the full wiring diagram. That will be your best friend in finding your problem.
