Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is***** am sorry to hear about your Envoy. Typically this is one of two things. Most of the time this is caused by the ignition switch. It is a very common failure. It can also be the body control module, but that is not as common as the switch. A voltage drop test of the switch needs to be done first. If both of these are fine then it may be an issue with the fuse box itself or the positive battery cable. I hope this helps. Please let me know if you have further questions.
