Dash lights issue 71 C10

I've read many threads to go about correcting the turn signal indicators being on. This Used to only be when the headlights are on. Now they are always on. The main issue now is when I turn on the AC/Heater switch (the vertical one) It's turning my dash light on, any advice?

Run a separate ground between the back of the cluster and the firewall.

Check/clean ALL grounds. There are 5 of them. Even if you run a ground from the cluster to the firewall (should be one there already) if the cab doesn't have a good ground to the frame you have nothing. The cab is mounted to the frame with those big rubber mounts which are excellent insulators...
