Rear view mirror "NOT WORKING"

Hi

I started my new sub project wich is the "Rear view mirror"

I have the following:
1- an electronic Rear view mirror.
2- blug and wire ready and connected.

But it is dead 100% nothing is working at all so I went to the local junk yard and tried 7 rearview mirrors and non worked from 99 models until 2001

This the blug diagram showing the voltage source.



As you can see only the middle is supplying the 12v and I found very week electric supply from the second pin a showing .6v or less

And I dont have the temp sensor as shown hear (red circle)



I took it from another thread (sorry for that)

Thanks

I found this diagram:



The owner of this diagram he used pins 1 and 2 to feed the mirror to work.

Could any of you please take a picture of the wires so I can compare it to what I have may be the pins are mis placed?

I couldn't figure whats wrong with it I fiund out that the previous owner disconnected the sun visors so I connected them and they worked (solved a secondary problem!!)

I will take the roof down and see whats going on there

try access thru the center console be removed first. then remove the headliner only if you need to. might save you some time.
