Service Rep: The digital rear view mirror is fine - there is no leak and the image in the mirror is clear.
Me: Hard to believe since you saw it 2 days ago when I made the appointment, but I’ll look at it. One look & I asked him to come look @ my truck. He went straight to surrender & got the Service Mananer.
SM: You‘re right. He checks the backup camera on the tailgate (not the inside rear view camera) so I pointed him in the right direction. He then climbs in the bed to clean the lens.
Me: Thinking - gee wish I had thought of that

.
SM then gets mechanic who checked it out.
Mech starts the truck, sees the foggy mirror & then turns on the backup camera view which is crystal clear. Tells the SM the problem can’t be the camera because if the camera was bad both images would be foggy. Mech goes to back of truck & cleans off backup camera lens. Once again I point out the second camera.
Me: How did you check for a leak in the CHMSL that might be causing moisture on the lens when you didn’t even know there was a camera there?
Mech: We’ll order a new camera and call you when it arrives.
It might actually be funny if it weren’t so sad………
