Strange dash lights problem

[Rangeley]

Hello All,

I noticed my cruise light and my high beam light on the dash come after about 20 seconds after the truck is shut off. I tried tapping on dash,diconnecting batteries,driving it a while etc. Nothing seems to affect it. Anybody seen this before?

What year is the truck and how many miles are on it? I just checked the GM website for recalls/ special policies but I am unable to find what I am looking for. Anyway, there seems to be some special policy for the IPC issues. You might try contacting your local GM dealer about this. There have ben quite a few customers into our dealership lately that have mentioned some letter that they have recieved about a special policy for vehicles upto 70k miles on them? Hopefully this helps.
