A neighbor just bought this 2006 GMC from a car dealer. All was good for a couple weeks and then it wouldn't start. AAA jumped it once and I personally did 2 times. First stop at the dealer they put a new battery in. It was good for 3 or 4 days, then I had to jump it again. The driver doesn't know cars at all and was told it was a kill switch someone put in that was draining the battery. You could hear the kill switch alarm recycling at every jump start. The car didn't start again but this time it wouldn't take a jump, by me and AAA. Was towed again for the 3rd time and the owner was told it was a condenser/capacitor?? I asked the owner to what exactly it was and he just showed me with his hands the basic size of it and said it had wires and fuse looking things in it. His words, not mine from what the mechanic showed him. He has no clue to where this part came from. I guess the wires were cleaned for now. The dealer cannot find what ever the heck the part is and I really don't want getting involved but just to say they are searching junkyards. I guess he was told the kill switch was from the factory and not the issue. Anyone have any clues? Also trying to tell this owner about parts availability with covid is stressing the heck out of him. I tried telling him to think of what garage owners are going through.
