when I switch on the A/C or heat the the flashers freeze, I can't shift from park, radio stops working

With the truck running when I switch on the A/C or heat the the flashers freeze, I can't shift from park, radio stops working, all dash indicator lights come on, and theres a loud click coming from the passenger side kick plate fuse panel. All fuses and relays are good. But when i remove relay # 6 everything is normal. Plug it back in and the problems come back. Every relay with the same number as #6 does this. Could this be a ground issue? Or do I have a much bigger problem on my hands.
