OK, I just joined a couple days ago, but have been reading for a couple weeks here since I bought my 2004 Colorado a month ago. It started to have an issue with the ignition. Symptom was that with the key out of ignition the radio, and dash lights would stay on even after locking the vehicle with the key less entry fob. Eventually the alarm would go off. Very frustrating.

I had read many issues with others on this site with so many different characteristics with the issue. Well, I finally figured it out. It simply was the ignition switch. The part cost $85 at the dealer and 1 hour of frustration getting the old one off. I am now stress free and feeling really good about the truck now. Someone posted that the ignition cost about $200 in a previous thread. Who ever you were you made me lose sleep over that one. Under $100 bucks and I am happy. Hope this helps someone out there?

I know this is an old thread but after searching the many other ignition problems this is the only one I saw that was the same as the problem I have. Pull out key and radio "P" indicator sometimes stay on. Alarm then goes off eventually after locking doors.

Do you have the part number from the switch you ordered? I have an 04 colorado crew cab.

Just went out and opened my door a couple mins ago and the battery was dead (wasn't driven since friday, so evidently it drained the darn battery)

If I replace switch do tumbler and key area swap into housing? (just looked at some on ebay) or do I get new keys?

You have to switch your tumblers to the new ignition cylinder. Take careful note as to order of placement on both sides.

to C'Fans.

That post was over four years ago. By now, he probably has it figured out.

For a free, easy, and temporary fix simply disable the accessory position.

I did this by removing the shroud around the steering column (3x T25 screws). Sitting in the seat, on the left of the column is a green connector going into the ignition switch. Take off the connector and remove the red striped wire from it. To do that, look for a little flap on the connector and flip it open. Then facing down the female end of the connector you'll see upper and lower holes. Identify which hole is the pin-release channel (I believe it is the upper), stick something in it, and you'll release the red striped wire's pin. Be GENTLE. Plug the green connector back in and test it out.

Anyhow you will lose accessories (but not the radio, which runs of the BCM, on mine anyhow). I have crank windows, power locks, and no alarm, so this was of little inconvenience if any.
