Default Electrical problem1987 dodge d100

1987 dodge d100 with no click no start. Clean truck with 40000 miles but all of the sudden I went out from running an errand and have no clicking at the relay when trying to start. I jumped the terminals at the starter to get home and it’s fine. I replaced the ignition switch; same issue. I have also replaced the starter relay and same scenario. Battery terminals got cleaned and wires are in good shape. Also the ac fan won’t turn on as well as the cabin light. Any thoughts? Thanks in advance. Also I did wire a push to start to work around this.

See if you are getting power at pin 30 on the starter relay, if that's ok, see if you get 12 volts on pin 85 (or maybe 86) with the ignition in the start position.
