Hi
Had you had just one code I could provide an educated guess from experience and prior diag on what could be to blame. However you have multiple codes, so it not that simple. This is going to require diagnostics to figure this out. Its going to end up being the module, switch, or shift motor, not the relays. Below is a file, can you do those tests?

You want a excellent 5 star answer & I would like to be rated the same for providing it. Consider I don't know your skill level & I can't see, smell, hear, or touch the vehicle. It may take a few back and forth replies. Try your best to respond with good detail so I can do the same. I normally log in at 3pm and work late. A rating is required. Your rating me, what I type. I am not an employee of this website, nor have control over the fees or the time it took to get a response. If you rate negative or not at all you still paid, but I get nothing. I want you pleased with me and my efforts, so let me know if your experience here has come up short.
Thanks Chris

yes. I have checked for power at the switch and have none.

The switch works of resistance, not power. Which of the above tests were you doing to come to this result?
