1998 Peterbilt HVAC wiring

I have a 98 peterbilt 379 that I was working on. The recircle/fresh air motor plug was ruined. Was changing the plug had ignition on while testing to see if everything is good before doing the connections properly. Simple mistake of leaving the ignition on and leaving to grab something both the wires of the recircle/fresh air sparked them selves.

Now the blower works but the freshair cntrl, temp cntrl and mode cntrl do not work anymore after that spark. Never had a issue before.

No fuse went off all are good, all the relays are good.
After looking at the schematic ; SCHEMATIC379 FAMILY SK25762 Schematic, Model 379 Family Wiring SK25762

I see that all these wires go to the Cab heat & AC cntrl which I assume is the hvac controller. Does this mean that I burnt that out ? I'm no electrician but can do some basics. Would just like some assistance if someones dealt with this.

Thanks

 

Thank you. That's exactly what it was.
