I don't know if anyone can help here, but thought their might be a GM service expert or someone who's had the same experience on here.
The wife has an 07 Yukon. Up until yesterday things have been fine. The "Service Battery Charging System" light came on. I had it checked (alt,battery and so on) Everything is working as it should. So I drive it all day yesterday, bring it home last night park it and go to bed. Now, this morning I went out to warm it up and nothing....I mean nothing! The only thing that had power was the cig lighter. I did some checking and found that the positive cable was so loose that I pulled it off without taking a wrench to it. That was some short lived hope....tightened it, went to start it...nothing again. So that brings me here, to my computer, to wonderful and informative Wake World! If anyone has any advice I'd sure appreciate it. I just want to avoid having it towed over something simple if that's the case. Thanks in advance.
By the way....I tried jumping it from my F-250...no dice.
