Sounds more like you have a major voltage issue, have you checked all of the power and grounds? This rig has a bunch of them, I would suggest you get a shop manual that shows the location of the connections, both power and ground, it will save you hours in tracking down the circuits. This rig also has check relays, and if they don't get the proper voltage they won't work right either.
