Good idea

I figured that the relay was under the dash and the solenoid was on the motor in the tailgate. I could be wrong about the relay location but the noise is coming from the tailgate

I thought of that but I figured this would be the same switch the dome light is on and the domelight isnt coing on when the tailgate is closed, it only comes on when the tailgate is open. I could be wrong though. I could search a schematic on all-data tonight.
As a matter of fact, where is the domelight switch for the tailgate? Its not a plunger style like a door jamb that I could see. Is it a mercury switch within the gate or a limit switch on the latch? I have no idea. Are there seperate switches for the domelight and the liftgate ajar light?
Regardless, although I would like to figure this out now, it is a pretty low priority. But if anyone has any additional ideas, I am open to your suggestions. Thankd for all the replies so far.
