ML Front Camera not working & heat seating problem

I have a 2015 ML250. Front view camera is not working, seems to be a relatively common fault.

Is it usually just the camera? Can somebody recomend an aftermarket part or seller, dealer price is outrageous.

Are there any codes to look for in an OBD scan? I have a MB iSoft scan tool.

Also have an intermittent issue with the driver seat heating sometimes not switching on. It heats properly when it does switch on si I doubt its the element, Sometimes there is no response from the heat seating switch

When it doesn't switch on the passenger side still works normally.

I have a similar issue in my 2014 ML350; the driver side heated seat doesn't regularly work. I'm 100% confident it's NOT the actual button, because when it does work, the subsequent pressing of the button works flawlessly to go from high - med- low and off.
What I have discovered.... is... If I turn the key to the electric ON position, and quickly press the seat heat button, it sometimes works. Then I start the car, and the seat heat works for a while. Sometimes, I have to turn the key to the electric ON position a couple of times; quickly hitting the seat heat but after each attempt. Strange....
Passenger heated seat works flawlessly.

I have replaced my front camera and the replacement is intermittent. I replaced the wiring harness as well.
