Yep, this happens when the lighting control module goes out, here is the location so you can swap it out. It is under the dash on the drivers side.

If the fuses are okay replace the LCM and then start a new question oft he stuck in park problem. Sorry, we only handle one problem per thread, please post your new question here, you must be logged in.
