Customer reply replied 8 years ago
here is what has happened. was on position 2 and it just went off a couple of days ago. so i put it on 3 and worked just fine. then the same thing for 1,2,4, and 5. the resistor was replaced about 6 mo ago. maybe it went bad.
Chevy Mechanic: BOBBYSS, Master Technician replied 8 years ago
Okay. It is very common for this resistor module to fail. If it was replaced with a new unit then it should be fine. The problem may be in the wiring. When the resistor module is replaced it is also recommended that the wiring connector be replaced as it becomes warped and makes poor connection.
