I switched out my resistor three times and the connectors seem like they were burning. When I turned it on the heat side up to the fourth setting. I have a 2017 Chevy trax and I see that sometimes it does have electrical issues and wondering what is going on here. I had a mechanic start the car to give heat but it still blew out. I am in a panic mode right now because this is such a small thing to fix and people are trying to charge almost $1000 to fix it which I don’t have and I’ve been doing gig work out of my car. Can anyone help me with this?
