Has anyone had there trunk light work off and on? Sometimes it comes on and sometimes not. I have tried activating the switch on the latch (rear compartment lid ajar switch) that is supposed to close the circuit but nothing happens. When it does come on turning the switch on and off does as should? Also tried testing ground on the switch but can't seem to find a good ground source. Any suggestions would be appreciated. If you can buy a new switch (rear compartment lid ajar switch) the GM part number might turn me in the right direction. The positive wire going to the light is the Orange/Black wire without the Entrapment Protection
