hello and thanks for any help i can get. about 3 months ago the back up camera was intermittent with a clicking noise left side of cluster as i could tell. so stopped hearing clicking and backup display has been saying service rear camera ever since. starting a couple days ago my check engine light starts flashing intermittently with same clicking sound. noticed when check engine light is on the backup camera started working and when check engine light goes off the camera the camera stops working. any help i can get is most appreciated. without my truck i am dead in the water, and will pay it forward for sure if i can avoid the dealer hourly rate. thanks to all
