My 04.5 er is on the blink. Driving yesterday with the air on and it shuts off. Display shows everything working, ie fan on high ac on etc...

My son found under the passenger side, three wires that connect under the blower. Very hot wires. He wiggled them and the air came back on. Went to the Chevy garage and they had a 100 dollar fix, that wasn't it. Completely different harness. Parts guy is saying this part doesn't exist on the diagram.
Anyone had any trouble like this? Not sure what or where to go.
