Customer Question
I have a 2010 Chevy...
I have a 2010 Chevy Colorado. When I turn the key nothing comes on except the passenger side air bag light cycles on and off. No dome light no cluster lights and the key does not engage the stater. Some disconnected a bunch of wires I reconnected what I saw was undone. Any ideas.

This is a tough one for me to answer myself from here.I will have to see if anyone else here can assist further on this that may have more info to help here.

I will open your question up for others here to see if someone else can assist further on this as there may be others here that may have more info on what to check or do with this issue.I hope you can get this resolved with ease.No need to reply to my last post here unless it is a last resort as it will keep your question locked to me and others will not be able to view it.If you feel you want to continue to work with me on this feel free to reply at any time but keep in mind in some cases it can be difficult to fully diagnose or help repair this without seeing your vehicle.

Thanks Pete

Do you have any suggestions or ideas?
Chevy Mechanic: Lou P., ASE Certified Technician replied 1 month ago

ok, thanks for the reply, so it appears that there may be a lot of issues , can you tell me or send me pictures of the wiring you had to repair and more of the story?

we need to make sure the car modules that talk to each other all have power, ground, and data line connection .

this can be easy or tough depending on what you have going on over there.

my info is only as good as the info you give me.

so if you are willing to give me all the details and help streamline this I can get you in the right direction if not fixed up.

Lou
