Hey guys, my heater resistor packed in and fan was only working on number 4. This only happened the other night so ordered a new one and it came today. Put it in and fan now working fine but after driving for about 5 mins there was an awful burning smell so I dropped the resistor out and it is really hot, is this normal for a new resistor and does it settle down or am I looking at a faulty one?

Cheers
