Starter issues. ..

then the specific ign switch output seems okay then.

will look for alarm diagram again.

any other peculiar stuff happening?

still no diagram. to disable the remote starter signal to isolate a possible crank condition look at the large harness as it travel from in the steering column down into the dash you will see a massive multi-circuit connector on the connector you can see three wires in a row that are inline yellow, red and the yellow again. pick the yellow one closest to outside edge of connector and not the one closest to center. follow that wire as best as you can where ever you can see it. the crank signal for the alarm unit will cut in or splice int to it if you can temporary restore it to normal stock and the problem remains then it is not the alarm starter causing it to randomly crank. that leaves mainly the ignition switch, starter solenoid or its relay. take a moment to soak this in and see what you come up with.

Well replaced the ignition switch and everything seems to be good except the hvac controls. . Time to find a new one I guess.

before you do be sure the brown wire to the blower switch and control around it has system voltage if not something is blocking the flow of power. if the both do then plug just the blower plug in the switch and with blower set to off ensure that the dark/green wire from blower switch to inline connector on the control head board has system voltage. that is the dark/green between the black wire and another dark/green wire. it also is the third one from an end of that connector. if it has sys volts when blower is off only and no volts when blower is on any speed. then control head is bonkers. does the fan work in any speed at all. if none at all then again something is blocking the main power to the entire control head. a funky fuse perhaps. if fuses 6, 12, 18 and 24 are powerless then there is a fault in power coming from the orange output of new ignition switch. if wipers and and switched power to radio is out as well then it might be farther back in the sys on the ign-a 40 amp mega-fuse under the hood. you get all that?
