My low oil light and coolant temp light are staying on when the keys are removed also I have lines across odometer. This truck doesn't get drove alot it sat for a week when this problem showed up

 

I have the same problem. Does it happen when it rains? From what I understand there is an electronic control mod under the dash that gets wet from a leaky windshield. I'm on here now trying to find info on the part and a fix. Let me know if you find anything out and I will do the same. Good luck

It's called a GEM module. It could just be bad but you might want to check your windshield for leaks. I have had this problem before but it went away after I replaceds the Altenator so I had hoped that was it. But now it's back so Im trying to fix it. I finally found my old post. Here is a link to my old post

Thanks guys I will look at the gem well I'm fixing the rear leaking glass this weekend. I wasn't aware that the front windshield leak to. It seems like this generation has quite it's share of problems

 

Well it's dried a few days and now the lights went off and everything is back to normal. I'm going to take the gem out Saturday and look for moisture
