My son was installing a radar/dash cam and running some wires under the dash. Obviously something went wrong because all of a sudden absolutely no power to start the Envoy and no interior anything. Was basically like there was no battery connected at all. I assumed he surged something when starting the truck and blew the battery but found it strange that there was no juice at all. Fuse #13 was blown and I put a new battery in it and all seemed ok for a few days. He went out last night and the truck was totally dead again this morning. Going to check all fuses and wiring under the dash -- but if something is shorting out the ign e circuit, shouldn't there at least be some juice to something from a brand new battery? Like if the MEGA 125 fuse was blown, why would it start for a few days and then fail again?
