i parked,removed key and continued listening to the radio. the dome light slowly went out. i instinctivly reached for the key when leaving and touched the empty ignition sw assm,moved it slightly and the dome light came on, and slowly went out again!. i touched the key hole and the light came on again, no key, just a finger touch...?!

 

One of GM's infamous ignition switch failures? Do you carry a lot of keys on the same ring as the ignition key?

 

Yes ignition. I have the same issue. My power will come on with no key. First time I noticed I went into a store came out to my truck and the radio was playing.

 

let me be clear, i have zero trouble, just noticed the light came back on for a moment.
