I just purchased this 2006 Denali XL about 1month ago with 120k and everything was working fine. Now i am having 2 weird issues.
1. The rear park assist doesn't seems to be working. usually with i put the truck in reverse there is 2 beeps and the mirror move down so i can see better. once i get close to and object the small speaker in the back starts making a beeping sound and as i get closer to an object it starts beeping more frequently. Now... nothing! no initial beep when i go into reverse and no beeps as i get closer to an object. But at least my side mirrors still move. I am not getting any error codes or messages.
2. My rear wiper doesn't work when i set it to low or high speed. however if i hit the rear washer button the wipers work as expected to wash the windows. Do i need a new wiper control board?
