Wiring harness connections are melted at the blower motor and resistor. Also did on my 06 Sedona. Worried about a fire. The circuit is not sized right. There are a lot of complaints on line about this.
Driving to montana from colorado over the summer, ac went out. Got it back to dealership, was told blower motor went bad - actually melted the plug and we had smoke in the van! replaced the blower motor and plug (out of pocket) from dealership since they said out of warranty due to mileage. Then, 3 weeks later, same problem. They replaced the wiring harness connector. 2 weeks later, same problem, replaced blower motor again and wiring pigtail connector to blower motor. A/c is one thing, but when entering into colorado winter driving, need heat for the windshield! repeated problem dozens of times over the last 2 months! vehicle isn't safe to drive now! went to another dealership, now that it's winter in colorado, need heat for windshield. Was told needed to replace full vehicle wiring harness at ~$1,800 parts + ~$1,100 labor and to "see if that would fix it. " nope! vehicle is not safe due to visibility due to defective heating for defrost! I'm finding this is a common problem for 2012 kia vehicles with climate control issues, blowers, etc! not sure if it's drawing too much power or what? have had two blower motors installed and wiring pigtails in 3 months, and not right. Vehicle not safe for my wife to drive with cold climate! this is incredibly dangerous! vehicles need to be recalled and immediately fixed!.
